A drywall calculator turns room measurements into a shopping list. Give it a length, a width and a wall height, and it works out how much surface area you have to cover, converts that area into full sheets of drywall, then sizes the joint compound, tape and screws that go with them. This one deducts standard door and window openings, lays the board out wall by wall the way a hanger would, and adds 10% as spare sheets by default, so the sheet count is what you will actually buy. Article outline: - What this drywall calculator works out - The drywall formula, step by step - A worked example: a 14 by 12 foot bedroom - Which drywall sheet size should you pick? - How much mud, tape and screws you need - Five tips for an accurate takeoff ### How many drywall sheets do I need for a 12x12 room? Buy 14 sheets of 4x8 for the walls of a 12 ft by 12 ft room with 8 ft ceilings, one door and one window. The walls are 384 sq ft, 348 sq ft net of the openings, and laid out wall by wall they take 12 sheets; the other 2 are spares. Add the 144 sq ft ceiling and it is 17 sheets laid out, 19 with spares. ### Does the calculator include a waste factor? Yes. It adds 10% by default, which is the standard allowance for cuts and offcuts in a rectangular room. You can change the waste percentage in the calculator, and 15% is a better figure for rooms with many angles, closets or stairwells. ### How much does a sheet of drywall cost? In the US a 4x8 half inch sheet typically runs about $12 to $20 depending on region, thickness and whether it is standard, moisture resistant or fire rated. Because pricing moves constantly, the calculator asks you to enter your own price per sheet rather than guessing on your behalf. ### Should I subtract doors and windows from drywall square footage? Yes for anything door sized or larger. This calculator deducts 21 sq ft per door, 15 sq ft per window and 112 sq ft per garage door, the standard allowances for a 3 ft by 7 ft door, a 3 ft by 5 ft window and a 16 ft by 7 ft garage door. Add anything else, like a patio slider or a pass-through, as a custom opening by width and height. Leave small openings like outlets and vents in, since cutting around them is what the waste factor covers. ### Can I use this drywall calculator in metric? Yes. Switch the unit toggle to metric and enter meters and centimeters. Your existing measurements are converted, and the results show total area in both square feet and square meters while sheet sizes stay in the imperial sizes sold in North America. ## Drywall Calculator for Walls and Ceiling URL: https://drywallplanner.com/walls-and-ceiling Summary: Drywall calculator for walls and ceiling together: total sheets, mud, tape and screws for a whole room in one pass, at 1.25 screws per sq ft overhead. When you drywall a full room you are really estimating two different surfaces at once. The walls are a perimeter times a height with openings cut out of them, and the ceiling is a simple length times width with no openings at all. This calculator has both switched on, adds them into one sheet count, and uses a higher screw purchasing allowance for the overhead portion of the job. Article outline: - Why walls and ceiling are calculated separately, then added - The whole-room formula - Worked example: a 16 by 13 foot living room - What changes when the ceiling is in scope - A sensible order of work for a full room ### How do I calculate drywall for walls and ceiling together? Work out the walls as perimeter times height minus openings, work out the ceiling as length times width, then add the two areas together before applying the waste factor and dividing by the sheet area. This page has both surfaces switched on so it does that for you. ### Do I need more screws for a ceiling than for a wall? Yes. Ceiling board carries its own weight in shear, so screws go closer together, typically 12 in on center in the field against 16 in on walls. This calculator uses one screw per square foot for walls and 1.25 per square foot for ceilings. ### Should the ceiling use thicker drywall? Often, yes. Five eighths inch board or half inch sag resistant board is the usual choice for ceilings, and it is required in many jurisdictions when joists are 24 in on center. The sheet count is the same either way, the board is just heavier and more expensive. ### Do I deduct anything from the ceiling area? Normally no. Light fixtures, can lights and vents are small cutouts covered by the waste allowance. Only deduct something genuinely large, such as an open stairwell or a two storey void, and in that case measure it and subtract it from the room dimensions you enter. ### How much joint compound for a whole room? Budget about 140 lb of all-purpose compound per 1,000 sq ft of board hung, which is roughly one 4.5 gallon box per 440 sq ft. The results card converts your board total into both pounds and boxes so you can buy in whole units. ## Drywall Calculator: Square Feet to Sheets URL: https://drywallplanner.com/square-feet Summary: Drywall square footage to sheets: gross wall area, opening deductions and net square feet, converted into sheets of 4x8 (32 sq ft) through 4x12 (48 sq ft). Drywall is estimated in square feet and sold in sheets, and almost every ordering mistake happens in the conversion between the two. Square footage is a measurement of the surface you have to cover. A sheet is a fixed 32, 36, 40 or 48 square feet of board that only rarely lands on your wall without a cut. This page shows both numbers side by side, so you can see the area, the waste allowance and the sheet count that follows from them. Article outline: - How to calculate drywall square footage - Converting square feet to sheets - Worked example: 850 square feet of wall - What a square foot of drywall costs - Getting the square footage right ### How many square feet is a sheet of drywall? A 4x8 sheet is 32 sq ft, a 4x9 is 36 sq ft, a 4x10 is 40 sq ft and a 4x12 is 48 sq ft. All standard sheets are 4 ft wide, so the length sets the area. ### How many sheets of drywall is 1,000 square feet? For 1,000 sq ft of surface with a 10% waste allowance you need 1,100 sq ft of board: 35 sheets of 4x8, 31 of 4x9, 28 of 4x10 or 23 of 4x12. Without any waste allowance it would be 32 sheets of 4x8. ### Is drywall square footage the same as floor square footage? No, and confusing the two is the most common estimating mistake. Floor area is length times width. Wall area is the perimeter times the wall height, which for a typical room is two to three times larger than the floor area. ### How do I convert drywall square feet to square meters? Divide square feet by 10.7639. So 500 sq ft is about 46.5 m². Switch the calculator to metric and it reports the total in both units, while keeping the North American sheet sizes. ### How much drywall do I need per square foot of house? A rough industry planning figure is 3.5 to 4 square feet of drywall per square foot of finished floor area for a whole house including ceilings and interior partitions. It is only a sanity check; for anything you are ordering, measure room by room. ## Drywall Ceiling Calculator URL: https://drywallplanner.com/ceiling Summary: Drywall ceiling calculator: enter the ceiling length and width for sheets, joint compound, tape and screws at 1.25 per sq ft, with 5/8 in board notes. A drywall ceiling calculator is the simplest takeoff in the trade and the hardest install. The area is just length times width with no openings to deduct, but the board goes up over your head, needs more screws, often needs to be thicker, and shows every flaw once daylight rakes across it. This page has walls switched off so the estimate covers the ceiling alone, with the ceiling screw density applied. Article outline: - The ceiling drywall formula - Worked example: a 20 by 14 foot ceiling - Ceiling drywall thickness and sagging - Hanging a ceiling without help - What a drywall ceiling costs ### How many sheets of drywall for a ceiling? Multiply ceiling length by width, add 10% for waste, then divide by the sheet area. A 12 by 12 ceiling is 144 sq ft, which is 159 sq ft with waste, so 5 sheets of 4x8 or 4 sheets of 4x12. ### What thickness of drywall should a ceiling be? Five eighths inch is the safe choice and is normally required when joists are 24 in on center. Half inch is acceptable at 16 in on center, and half inch sag resistant board is a good middle option that weighs less than five eighths. ### How many screws per sheet on a ceiling? About 40 screws per 4x8 sheet, working at roughly 12 in on center in the field. This calculator applies 1.25 screws per square foot of ceiling, against one per square foot on walls. ### Which direction should ceiling drywall run? Perpendicular to the joists in almost every case. It spreads variation in joist depth across several members, puts the tapered edges across the span where they are easiest to finish, and lets you stagger butt joints between rows. ### Do I deduct light fixtures from ceiling square footage? No. Can lights, fan boxes and vents are small cutouts whose offcuts become scrap, and the 10% waste allowance already covers them. Only subtract something genuinely large, such as an open stairwell. ## Drywall Cost Calculator URL: https://drywallplanner.com/cost Summary: Drywall cost calculator with board, finishing and labor lines: enter your sheet price and labor rate for an installed total, often $1.80 to $3.30 per sq ft. A drywall cost calculator has to separate three very different numbers: the board, the finishing materials, and the labor to hang and finish it. Board is the easiest and the smallest, usually under a quarter of an installed price. Labor is the largest and the most variable. This page keeps the three as separate lines so you can compare a contractor quote against your own material cost and see exactly where the money is going. Article outline: - The three lines in a drywall price - How the cost estimate is built - Worked example: pricing a 14 by 12 bedroom - What moves a drywall quote up or down - Using this to compare contractor quotes ### How much does it cost to drywall a room? For a typical 12 by 12 bedroom with walls and ceiling, expect roughly $1,000 to $1,700 installed in most US markets, or about $400 to $550 in materials if you do the work yourself. Enter your own sheet price and labor rate above for a figure that matches your area. ### How much does drywall cost per square foot installed? About $1.80 to $3.30 per square foot of drywall for standard residential work, covering board, finishing materials and labor to a level 4 finish. High ceilings, level 5 finishes and specialty board push it higher. ### What does drywall labor cost per square foot? Hanging and finishing commonly runs $1.20 to $2.50 per square foot, and it is usually the largest of the three cost lines. The default of $1.65 in this calculator sits in the middle of that range; replace it with a local rate if you have one. ### Does the cost estimate include primer and paint? No. The estimate covers board, finishing materials and the labor to hang and finish. Primer and paint are a separate trade and a separate line, typically another $0.50 to $1.00 per square foot supplied and applied. ### Is it cheaper to buy 4x12 drywall sheets? Usually yes on a per square foot basis, and they also cut finishing labor by reducing butt joints. The catch is handling: a 4x12 half inch sheet weighs about 82 lb and needs two people and a clear path, so for tight stairwells 4x8 can still be the practical choice. ## Drywall Layout Calculator URL: https://drywallplanner.com/layout Summary: Drywall layout calculator that hangs real sheets on each wall, cuts around doors and windows and reuses offcuts, so you buy only the sheets the job takes. A square-foot estimate tells you how much board covers the room. A layout tells you how many sheets it takes to get there, which is not the same number. A 9 ft wall needs a 1 ft strip that has to come from somewhere, a door leaves an offcut that may or may not fit the next wall, and a 12 ft sheet on an 11 ft wall wastes a foot every row. This planner works it out the way a hanger does: it places each sheet, cuts it, keeps the offcut, and only opens a new sheet when nothing in the pile fits. Article outline: - How the layout planner places sheets - Reading the diagrams - How the planner and the main calculator agree - Layout rules worth following on any job Sources: - USG: https://www.usg.com/content/dam/USG/pdpmovedocuments/sheetrock-gypsum-panels-installation-guide-en-J371.pdf - Gypsum Association: https://www.gypsum.org/wp-content/uploads/2011/11/GA-216-2010.pdf ### Does the planner agree with the drywall calculator? Yes, for the same room. Both lay every piece out, rip strips from one sheet for several walls, reuse offcuts and add one spare per ten sheets. The calculator places doors and windows in standard spots, so if yours sit elsewhere the planner can come out a sheet higher or lower. ### Should drywall be hung horizontally or vertically? In homes, horizontally is the default: fewer feet of seam, and the tapered seam sits at a convenient height. Vertical hanging makes sense when the sheet length matches the wall height, for example 9 ft sheets on 9 ft walls, or where a code or fire assembly requires it. Auto mode compares both for your room. ### What does the number on each piece mean? It is the sheet the piece is cut from, counted in the order the planner opens them. Pieces with the same number come from the same sheet, and shaded pieces are offcuts reused from an earlier sheet. ### How do I enter a door that is not 3 by 7 ft? Add the opening, then change its width, height or sill. Any change turns it into a custom opening. Offset is measured from the left end of the wall as you face it, and sill is the height of the bottom edge above the floor. ## Drywall for 8 ft Walls URL: https://drywallplanner.com/drywall-calculator/8-foot-walls Summary: How much drywall a room with 8 ft walls takes: 4x8 versus 4x12, horizontal versus vertical, compared for your room with a sheet layout diagram for every wall. Most American houses built in the last seventy years have 8 ft ceilings, and drywall is sized around them. Two 4 ft wide sheets hung horizontally make exactly 8 ft, so there is no strip to rip, and the only real decision is sheet length. That decision matters more than people expect: in a 12 by 14 room, 4x12 board takes 9 sheets where 4x8 takes 14, and every extra sheet in a row is another butt joint to feather out. Article outline: - Why 8 ft walls are the easy case - Choosing a sheet length and orientation Sources: - USG: https://www.usg.com/content/dam/USG/pdpmovedocuments/sheetrock-gypsum-panels-installation-guide-en-J371.pdf - Gypsum Association: https://www.gypsum.org/wp-content/uploads/2011/11/GA-216-2010.pdf - USG: https://pdf.lowes.com/productdocuments/1e9414cb-f0ea-4e04-9da2-9e68d567f06f/48873812.pdf ### How many sheets of drywall for a 12 by 12 room with 8 ft ceilings? The walls are 384 sq ft. Laid out in 4x12 board that is exactly 8 sheets with 48 ft of seams and no butt joints, or 12 sheets of 4x8. The 144 sq ft ceiling adds 3 sheets of 4x12. The main drywall calculator lays the walls out the same way and adds one spare per ten sheets, so it says 9 sheets of 4x12 or 14 of 4x8. ### Should I hang drywall horizontally on 8 ft walls? In homes, yes. It means fewer feet of seam, puts the tapered joint at a comfortable 4 ft, and bridges studs that are slightly out of line. Vertical 4x8 avoids butt joints but is more common in commercial work. ### Why does the main drywall calculator show more sheets than this page? This page shows the sheets in each layout, with ripped strips and offcuts reused. The main calculator runs the same layout engine and then adds 10% as spare sheets for breakage and miscuts, so its number is the one to order. Add one spare per ten sheets to any count on this page. ## Hanging Drywall on 9 ft Walls URL: https://drywallplanner.com/drywall-calculator/9-foot-walls Summary: Hanging drywall on 9 ft walls: compare 48 in board plus a 12 in strip, 54 in board and vertical 4x9 for your room, with seams and a diagram of every wall. Nine foot ceilings are now common in new construction, and they break the neat arithmetic of 48 in board. Two rows cover 8 ft and leave a foot. There are three ways to cover it: rip a 12 in strip from a standard sheet, buy 54 in wide board so two rows make exactly 9 ft, or hang 9 ft sheets vertically. In a 12 by 12 room the difference is stark: 54 in board takes 8 sheets and 48 ft of seams, 48 in board takes 9 sheets and twice the seams, and vertical 4x9 takes 12 sheets.

The walls are 432 sq ft. In 54 in x 12 ft board it takes 8 sheets with 48 ft of seams. In 48 in x 12 ft board with ripped 12 in strips it takes 9 sheets and 96 ft of seams. In 4x9 hung vertically it takes 12, and in 4x8 hung horizontally 14. The ceiling adds 3 sheets of 4x12. ### Is 54 inch drywall worth it for 9 ft walls? Usually, if you can get it in the length you need. Two rows make exactly 9 ft, so there is no strip seam: in a 12 by 12 room it saves a sheet and halves the feet of seam compared with 48 in board. It is often a special order, so ask your supplier before planning around it. ### Should the strip go at the top or the bottom of a 9 ft wall? At the bottom. The top row goes tight to the ceiling with its factory edge, the strip goes at the floor, and baseboard covers its cut edge. A strip at the top would put a hard-to-finish cut edge at the most visible line in the room. ### Why does the main drywall calculator show more sheets than this page? This page shows the sheets in each layout, with ripped strips and offcuts reused. The main calculator runs the same layout engine and then adds 10% as spare sheets for breakage and miscuts, so its number is the one to order. Add one spare per ten sheets to any count on this page. ## What Size Drywall for 10 ft Walls? URL: https://drywallplanner.com/drywall-calculator/10-foot-walls Summary: What size drywall for 10 ft walls: vertical 4x10, three rows of 48 in board or 54 in board plus a strip, compared for your room with sheets and seams. At 10 ft the extra height is half a sheet, which changes the trade-offs again. Horizontal 48 in board needs a third row, a 2 ft strip, and every piece above 8 ft is lifted overhead. 54 in board covers 9 ft in two rows and leaves a 1 ft strip. Vertical 4x10 sheets cover the wall in one piece with no butt joints at all. The sheet counts are close, so the deciding factor is usually taping and how the board gets into the room. Article outline: - What size drywall for 10 ft walls? - What changes above 9 ft Sources: - USG: https://pdf.lowes.com/productdocuments/1e9414cb-f0ea-4e04-9da2-9e68d567f06f/48873812.pdf - National Gypsum: https://images.thdstatic.com/catalog/pdfImages/9a/9a36dd13-c72c-4818-91ef-0303d5627ea6.pdf - Georgia-Pacific: https://www.buildgp.com/product/toughrock-fireguard-x-stretch-54-gypsum-board - USG: https://www.usg.com/content/dam/USG/pdpmovedocuments/sheetrock-gypsum-panels-installation-guide-en-J371.pdf ### How many sheets of drywall for 10 ft walls? For a 12 by 12 room the walls are 480 sq ft: 12 sheets of 4x10 hung vertically, 10 sheets of 48 in x 12 ft hung horizontally with ripped strips, or 9 sheets of 54 in x 12 ft. The table on this page gives the count for six common room sizes, and the planner above works it out for yours. ### Should drywall be hung vertically on 10 ft walls? It is a good option when you can buy 4x10 board: one piece floor to ceiling, no butt joints, no ripping and the least feet of seam. It uses a couple more sheets than a horizontal layout and needs straight studs, since every seam lands on one. ### Why does the main drywall calculator show more sheets than this page? This page shows the sheets in each layout, with ripped strips and offcuts reused. The main calculator runs the same layout engine and then adds 10% as spare sheets for breakage and miscuts, so its number is the one to order. Add one spare per ten sheets to any count on this page. ## Garage Drywall Calculator URL: https://drywallplanner.com/garage-drywall Summary: Garage drywall calculator that splits the order into 5/8 in type X and 1/2 in board by IRC Table R302.6, with the garage door deducted and attic options. An attached garage is the one room in a house where the drywall is a fire barrier rather than a finish. The International Residential Code sets out exactly which surfaces need board and how thick it must be, in Table R302.6. Getting it wrong is expensive twice: once when the inspector fails the framing, and again when 1/2 in board has to come down so 5/8 in type X can go up. This calculator applies the table to your garage and counts each kind of board separately. Article outline: - What the code requires - Hanging the type X ceiling - The door into the house Sources: - International Code Council: https://codes.iccsafe.org/content/IRC2024P1/chapter-3-building-planning - International Code Council: https://codes.iccsafe.org/content/IRC2024P1/chapter-7-wall-covering - International Code Council: https://codes.iccsafe.org/content/IRC2021P1/chapter-3-building-planning - International Code Council: https://codes.iccsafe.org/s/IRC2024V2.0/chapter-3-building-planning/IRC2024V2.0-Pt03-Ch03-SecR302.6 ### Does a garage ceiling need type X drywall? Under the 2024 IRC, only when part of the dwelling unit is above the garage; then the ceiling needs at least 5/8 in type X. With only attic above, the model code requires 1/2 in gypsum board on the garage side. Local amendments often require more, so check before ordering. ### Do all garage walls need drywall? No. The model code requires board on walls shared with the house, on walls that support a floor above the garage, and on exterior walls within 3 ft of the house. Other walls are optional, though most people board them for appearance and to protect the insulation. ### Is 5/8 in type X the same as fire-rated drywall? Type X is the ASTM designation for gypsum board with a specially formulated core that holds together longer in a fire. It is the board people mean when they say fire-rated, and it is the board Table R302.6 requires under living space. ## Garage Drywall Code Requirements URL: https://drywallplanner.com/garage-drywall/code-requirements Summary: Garage drywall code requirements in four questions: which walls and ceiling need board, where 1/2 in is enough and where IRC R302.6 calls for 5/8 in Type X. An attached garage is the one room where drywall is a fire separation rather than a finish, and the International Residential Code spells out exactly what it needs in Table R302.6. The short version: walls shared with the house need at least 1/2 in gypsum board on the garage side, a ceiling under any part of the house needs 5/8 in type X, and a ceiling with only attic above needs 1/2 in. The checker applies the full table to your garage, including the walls that hold up a room above and the rule for detached garages within 3 ft of the house. Article outline: - The four rows of Table R302.6 - What type of drywall for a garage ceiling? - The door between the garage and the house - Check your local code Sources: - International Code Council: https://codes.iccsafe.org/content/IRC2024P1/chapter-3-building-planning - International Code Council: https://codes.iccsafe.org/content/IRC2024P1/chapter-7-wall-covering - International Code Council: https://codes.iccsafe.org/content/IRC2021P1/chapter-3-building-planning - International Code Council: https://codes.iccsafe.org/s/IRC2024V2.0/chapter-3-building-planning/IRC2024V2.0-Pt03-Ch03-SecR302.6 ### What are the drywall requirements for an attached garage? Under 2024 IRC Table R302.6: at least 1/2 in gypsum board on the garage side of walls shared with the house and of a ceiling with only attic above, at least 5/8 in type X on a ceiling with any part of the house above, and at least 1/2 in on the walls that support that floor. Local codes can require more. ### Can I use regular drywall in my garage? On walls shared with the house and on a ceiling under an attic, yes: the model code asks for at least 1/2 in gypsum board, and standard 1/2 in board meets that. Under a bedroom or other part of the house the ceiling must be 5/8 in type X, and regular board does not qualify. Many jurisdictions require type X everywhere, so confirm locally. ### Does a detached garage need drywall? Not under Table R302.6, unless it is less than 3 ft from the house on the same lot; then the walls within that 3 ft need at least 1/2 in gypsum board on the inside. A detached garage with a living unit above it is a different case that your building department will treat as a dwelling. ### Do I have to tape and finish garage drywall? The IRC table sets the board, not the finish. Many inspectors expect at least a coat of compound over tape on joints and fasteners in the separation. Ask your inspector before you leave the joints bare. ## How Many Sheets of Drywall for a 2 Car Garage? URL: https://drywallplanner.com/garage-drywall/2-car-garage Summary: Sheets of drywall for a 2 car garage at 20x20, 22x22 and 24x24, with 8, 9 and 10 ft walls and attic or living space above, from a sheet-by-sheet layout. A 2 car garage takes about 21 to 27 sheets of 4x12 drywall with 8 ft walls, from a 20 x 20 ft garage to a 24 x 24 ft one, walls and ceiling included and a 16 x 7 ft door deducted. Taller walls add a few sheets, and living space above changes which sheets they are: the ceiling becomes 5/8 in type X. The table below gives the count for each common size and height, laid out sheet by sheet rather than estimated from area. Article outline: - What the table assumes - Common 2 car garage sizes - Which sheets need to be type X? Sources: - International Code Council: https://codes.iccsafe.org/content/IRC2024P1/chapter-3-building-planning - International Code Council: https://codes.iccsafe.org/content/IRC2021P1/chapter-3-building-planning ### How many sheets of drywall for a 2 car garage? For a 22 x 22 ft garage with 8 ft walls, about 25 sheets of 4x12 for the walls and ceiling, with a 16 x 7 ft door deducted. With 9 ft walls it is about 28, and with 10 ft walls about 29. Add one spare per ten sheets. ### How much drywall for a 2 car garage with a room above? About the same number of sheets, but the ceiling has to be 5/8 in type X. For a 22 x 22 ft garage with 8 ft walls that is 11 sheets of type X for the ceiling and 14 sheets of 1/2 in for the walls. ### Should I use 4x8 or 4x12 drywall in a garage? 4x12 if you can handle it. Garage walls are long and tall, so 12 ft sheets mean far fewer butt joints to tape, and a garage ceiling is usually hung with a lift either way. 4x8 is easier to carry and fit through a door. ## Drywall for a 20x20 Garage URL: https://drywallplanner.com/garage-drywall/20x20 Summary: Drywall for a 20x20 garage: sheets for walls and ceiling at 8, 9 and 10 ft, the Type X split with living space above, mud, tape, screws and wall diagrams. A 20 x 20 ft garage with 8 ft walls takes 21 sheets of 4x12 drywall for the walls and ceiling, laid out sheet by sheet with a 16 x 7 ft garage door and one entry door deducted. That is 507 sq ft of wall and 400 sq ft of ceiling. With 9 ft walls it is 23 sheets, and with 10 ft walls 24. If there is a room above, 9 of the sheets, the whole ceiling, must be 5/8 in type X.

One 4.5 gallon pail of all purpose joint compound finishes about 14 sheets of 4x8 drywall at a normal level 4 finish. That comes from USG's published coverage of about 10 gallons per 1,000 sq ft of board, which covers the tape coat and two finish coats over flat joints, inside corners and outside corners. A lightweight compound stretches a little further, a level 5 skim coat uses a lot more, and a garage left at level 2 uses roughly half as much. The calculator does the arithmetic for your job.

About 14 sheets of 4x8 per 4.5 gallon pail of all purpose compound at a normal level 4 finish, from USG's 10 gallons per 1,000 sq ft. About 15 sheets with lightweight compound, around 9 to 10 at level 5, and about 28 at level 2. ### How much drywall mud do I need for a 12x12 room? The walls of a 12x12 room with 8 ft walls are 384 sq ft of board and the ceiling 144 sq ft, about 17 sheets of 4x8 in all. At level 4 that is about 5.3 gallons of all purpose compound, so two 4.5 gallon pails. ### How much does a bucket of drywall mud weigh? A 4.5 gallon pail of conventional all purpose compound weighs 61.7 lb according to USG's and National Gypsum's product sheets. Lightweight compounds weigh noticeably less for the same volume. ## Drywall Screw Calculator URL: https://drywallplanner.com/drywall-screw-calculator Summary: Drywall screw calculator: screws per 4x8 or 4x12 sheet on walls and ceilings at 16 or 24 in framing, a pattern diagram, and screws per pound and box. A 4x8 sheet of drywall hung across studs 16 in on center takes 28 screws on a wall and 35 on a ceiling. That follows directly from the fastening rules: the sheet lands on seven studs, and the IRC and the Gypsum Association call for screws at most 16 in apart along each stud on walls and 12 in apart on ceilings, kept 3/8 in in from the edges. A 4x12 sheet takes 40 on a wall and 50 on a ceiling. The calculator draws the pattern and turns your sheet count into pounds and boxes. Article outline: - Drywall screw spacing - How many drywall screws in a 5 lb box - Can you use fewer screws?

At 24 in framing it is 25 on either, because walls then need screws every 12 in too. ### How many screws per 4x12 sheet of drywall? 40 on a wall at 16 in framing and 50 on a ceiling. At 24 in framing, 35 on either. ### How many drywall screws in a 1 lb box? About 258 of the #6 x 1-1/4 in coarse-thread size, 200 of 1-5/8 in and 175 of 2 in, by Grip-Rite's published counts. ### What length drywall screw for 1/2 inch drywall? 1-1/4 in coarse-thread Type W screws into wood studs, which is what USG recommends for 3/8, 1/2 and 5/8 in board. The minimum is 1-1/8 in for 1/2 in board, because the screw must reach at least 5/8 in into the wood. ## Drywall Tape Calculator URL: https://drywallplanner.com/drywall-tape-calculator Summary: How many rolls of drywall tape a room needs, from the actual seams in a sheet layout plus the inside corners, in 250 or 500 ft paper rolls or mesh tape. USG's rule of thumb is about 370 ft of joint tape per 1,000 sq ft of board, and for a quick estimate it works. But tape goes on joints, not on area: a room hung in 4x12 sheets has far fewer feet of seam than the same room in 4x8, and every inside corner takes tape whatever the board. This calculator lays the board out sheet by sheet, measures every seam where two pieces meet, adds the inside corners and the wall-to-ceiling joint, and turns the total into rolls.

For a 14 x 12 ft room with 8 ft walls and a ceiling in 4x12 board, the calculator above measures the seams and corners from the layout and rounds up to 250 or 500 ft rolls. As a quick check, USG gives about 370 ft of tape per 1,000 sq ft of board. ### How much paper tape for drywall per sheet? About 12 ft per 4x8 sheet by USG's 370 ft per 1,000 sq ft. The real figure depends on the layout: longer sheets mean fewer butt joints and less tape. ## Corner Bead Calculator URL: https://drywallplanner.com/corner-bead-calculator Summary: Corner bead calculator: outside corners, window returns, cased openings and soffits cut from 8 or 10 ft sticks, with offcuts reused and splices counted. Corner bead is sold in sticks, and the count is a cutting problem, not an area problem. An 8 ft corner takes one 8 ft stick; a 5 ft window return leaves a 3 ft offcut that can finish a window head. This calculator lists every edge that needs bead, cuts them from sticks longest first, reuses an offcut whenever one is long enough for a whole run, and tells you where a run is longer than a stick and needs a splice. Article outline: - Where corner bead goes - Metal, paper-faced or vinyl Sources: - ClarkDietrich: https://www.clarkdietrich.com/sites/default/files/media/documents/CD_Drwyall_Beads-Trims_Catalog.pdf - USG: https://images.thdstatic.com/catalog/pdfImages/b4/b4b21176-4bdb-4bd7-97eb-82fdf8a847cf.pdf - Trim-Tex: https://trim-tex.com/products/corner-bead-and-archway - Gypsum Association: https://www.gypsum.org/wp-content/uploads/2011/11/GA-216-2010.pdf ### How many sticks of corner bead do I need? One per outside corner when the stick is at least as tall as the wall, plus whatever the window returns and soffits need after offcuts are reused. Enter your corners and openings above for the count and the cut plan. ### What length does corner bead come in? Metal and vinyl bead are stocked in 8, 9, 10 and 12 ft sticks by ClarkDietrich and Trim-Tex. Paper-faced bead is mostly 8 and 10 ft, and USG adds 9 ft. Use the stick that covers your wall height in one piece. ### How do you fasten metal corner bead? USG says to fasten metal bead through the small holes in its flanges every 9 in. Paper-faced bead needs no fasteners: it is pressed into a bed of joint compound. Trim-Tex vinyl bead is sprayed with adhesive and stapled every 6 to 8 in on both legs. ## Skim Coat Calculator URL: https://drywallplanner.com/skim-coat-calculator Summary: How much joint compound to skim coat walls or ceilings: area, coats and product give gallons and pails, with manufacturer coverage for a level 5 skim. A skim coat is a thin layer over the whole surface, the step that turns a level 4 finish into level 5, or that flattens a patched and damaged wall. It uses far more material than taping, because it covers every square foot instead of just the joints. USG rates its sprayed primer-surfacer at about 100 to 125 sq ft per gallon, and one coat can replace both the skim and the prime of a level 5 finish. For thinned joint compound no manufacturer publishes a skim figure, so the calculator starts at 100 sq ft per gallon per coat, the arithmetic for a coat about 1/64 in thick, and lets you change it. Article outline: - When you need a skim coat - How skim coating uses compound Sources: - USG: https://www.usg.com/content/dam/USG_Marketing_Communications/united_states/product_promotional_materials/finished_assets/sheetrock-primer-surfacer-application-tips-en-J1810.pdf - USG: https://pdf.lowes.com/productdocuments/e3e981b1-7742-4f3b-98ce-75fb0984c279/07609385.pdf - National Gypsum: https://www.nationalgypsum.com/design-resource-center/faq/webinar-q-a-finishing-gypsum-board - Gypsum Association: https://www.gypsum.org/wp-content/uploads/2011/11/GA-216-2010.pdf ### How much joint compound for a skim coat? Area times coats, divided by the coverage per gallon, rounded up to whole pails. For thinned compound, about 100 sq ft per gallon per coat is a starting point for a thin coat; a 1,000 sq ft room skimmed once is about 10 gallons, three 4.5 gallon pails. Check your own coverage on a test area. ### Should I skim coat with all purpose or lightweight compound? USG lists conventional and lightweight all purpose compounds for skim coating, but not setting-type compound. Lightweight compounds sand more easily, which matters over a large area. A sprayed primer-surfacer is the fastest route to level 5 over new board. ## Drywall Texture Calculator URL: https://drywallplanner.com/texture-compound-calculator Summary: How much texture material for orange peel, knockdown, spatter or a popcorn ceiling patch, by square feet, from the manufacturer coverage per bag. How far a bag of texture goes depends on the pattern: a fine orange peel spreads thin, a heavy knockdown puts down more material per square foot, and a popcorn ceiling is mostly aggregate. Manufacturers publish a range rather than a figure per pattern, so the calculator orders for the heavy end and shows the light end beside it: spray texture, powder 500 to 2,000 sq ft per 50 lb bag, spray texture, ready-mix 300 to 700 sq ft per 3.5 gal carton, popcorn ceiling 256 to 320 sq ft per 32 lb bag, popcorn patch, aerosol 4 sq ft per 1 pint can.

Divide the ceiling area by the coverage of the product. A 12 x 12 ceiling of 144 sq ft takes one 50 lb bag of powder texture for any pattern, or one 32 lb bag of popcorn texture. ## Drywall Weight Calculator URL: https://drywallplanner.com/drywall-weight-calculator Summary: How much a sheet of drywall weighs by thickness and size, 1/4 in to 5/8 in type X, plus two-sheet bundles and how many sheets your truck can carry per trip. A 4x8 sheet of standard 1/2 in drywall weighs about 51 lb, a sheet of 5/8 in type X about 70 lb, and a lightweight 1/2 in panel about 40 lb, by USG's published weights per square foot. Multiply by the sheet area for bigger sheets: a 4x12 sheet of 5/8 in type X is over 100 lb. The calculator does the arithmetic for the board you are buying and tells you how many trips your truck will take.

About 70 lb for a 4x8 sheet of standard 5/8 in type X, at USG's 2.2 lb per sq ft, and about 106 lb for a 4x12. Lightweight 5/8 in type X is about 58 lb for a 4x8. ### How much does a 4x8 sheet of 1/2 drywall weigh? About 51 lb for regular 1/2 in board at 1.6 lb per sq ft, and about 40 lb for lightweight 1/2 in panels at 1.25 lb per sq ft. ### How many sheets of drywall in a bundle? Two. USG and Georgia-Pacific both bundle board in pairs, face to face, taped at the ends. ## 1/2 vs 5/8 Drywall URL: https://drywallplanner.com/compare/half-inch-vs-five-eighths-drywall Summary: 1/2 vs 5/8 drywall for your room: price difference, weight (about 51 lb vs 70 lb per 4x8 sheet), screw length and where the IRC requires 5/8 in Type X. Half inch drywall is the default for residential walls and ceilings; five eighths inch is heavier, stiffer and, as type X, fire rated. For the same room the sheet count is the same, so the difference is the price per sheet times the number of sheets, plus a lot more weight to carry overhead. A 4x8 sheet of 5/8 in type X weighs about 70 lb against about 51 lb for regular 1/2 in and 40 lb for lightweight 1/2 in, by USG's published weights. The calculator works out the dollar difference for your room with your own prices.

The difference is your supplier's price gap per sheet times the number of sheets, and the sheet count is the same for both. Enter both prices in the calculator for your room. Labor often adds more than the board, because the heavier sheets are slower to hang. ### How much does a sheet of 5/8 drywall weigh? About 70 lb for a 4x8 sheet of standard 5/8 in type X, at USG's published 2.2 lb per sq ft, and about 58 lb for USG's lightweight 5/8 in type X at 1.8 lb per sq ft. A 4x12 sheet of standard type X is about 106 lb. ### Should I use 5/8 drywall on ceilings? It is required on a garage ceiling with part of the house above, and needed at 24 in framing when you will spray a water-based texture, unless you use 1/2 in sag-resistant ceiling board. Otherwise 1/2 in board meets code on ceilings at 16 in framing, or 24 in when hung across the framing. ## Vaulted Ceiling Drywall Calculator URL: https://drywallplanner.com/drywall-calculator/vaulted-ceiling Summary: Vaulted ceiling drywall calculator: sloped planes and gable triangles from span and pitch, sheets from a layout, and how many more than a flat ceiling. A vaulted ceiling is two areas a flat ceiling does not have: the sloped planes, which are longer than the room is wide, and the two gable triangles at the ends. At a 6 in 12 pitch the slopes are about 12% larger than the flat ceiling they replace, and the triangles add more on top. The calculator works both out from the span and the pitch, lays every surface out sheet by sheet, and shows the difference against a flat ceiling in the same room. Article outline: - How the vault is measured - Hanging drywall on a vaulted ceiling Sources: - International Code Council: https://codes.iccsafe.org/content/IRC2024P1/chapter-7-wall-covering - Fine Homebuilding: https://www.finehomebuilding.com/project-guides/drywall/estimating-materials - Fixr: https://www.fixr.com/costs/drywall-installation - Gypsum Association: https://www.gypsum.org/wp-content/uploads/2011/11/GA-216-2010.pdf ### How much more drywall does a vaulted ceiling need? The slopes alone are 5 to 41% larger than the flat ceiling, from a 4 in 12 to a 12 in 12 pitch, and the gable triangles add more. For a 14 x 16 ft room at 6 in 12, the calculator above shows the extra in sheets. ### Is drywall on a vaulted ceiling a ceiling or a wall for fastening? Neither the IRC nor the Gypsum Association has a separate rule for slopes; both split only walls and ceilings. Fastening the slopes as a ceiling, screws no more than 12 in apart, is the conservative reading. The gable triangles are walls. ## Stairwell Drywall Calculator URL: https://drywallplanner.com/drywall-calculator/stairwell Summary: Stairwell drywall calculator: rake walls, end wall and sloped ceiling from the floor-to-floor height and the IRC 7-3/4 in riser limit, plus sheet length. The walls beside a stair are the awkward part of any drywall job: they are taller than a room, cut on an angle, and too high to reach from the stairs themselves. The board follows the flight, so each side wall is a parallelogram, as tall above the nosing line as the headroom, and as long as the stair's horizontal run. The calculator finds the run from the floor-to-floor height using the code's limits on riser height and tread depth, then works out each surface. Article outline: - From floor height to wall area - Choosing sheet length for a stairwell - The space under the stair - Working above a stair Sources: - International Code Council: https://codes.iccsafe.org/content/IRC2024P1/chapter-3-building-planning#IRC2024P1_Pt03_Ch03_SecR318.7 - International Code Council: https://codes.iccsafe.org/content/IRC2024P1/chapter-7-wall-covering - USG: https://www.usg.com/content/dam/USG/pdpmovedocuments/sheetrock-gypsum-panels-installation-guide-en-J371.pdf ### How do you drywall around stairs? Hang the end wall and the sloped ceiling first, then the rake walls in long sheets laid along the flight, cutting the bottom edge to follow the stringer. Use the longest sheet that spans the slope so you tape as few joints as possible from a ladder. ### How much drywall for a stairwell? For a 9 ft floor-to-floor stair with 10 in treads, walls on both sides 7.5 ft above the nosing, an end wall and a sloped ceiling, the calculator above gives the area and sheets. Change the inputs to match your stair. ## Cost to Drywall a Closet URL: https://drywallplanner.com/drywall-cost/closet Summary: Cost to drywall a closet: materials from the closet size, labor at your rate or the contractor minimum ($400 default), whichever is higher, plus DIY cost. A closet is one of the smallest drywall jobs and one of the most expensive per square foot to hire out. The board and mud are a few sheets and a pail, but taping takes three trips on three days whether it is a closet or a living room, so most contractors charge a minimum for small jobs. That minimum, not the square footage, usually sets the price. The calculator shows both numbers so you can see which one you are paying. Article outline: - What a closet costs - Doing it yourself Sources: - HomeAdvisor: https://www.homeadvisor.com/cost/walls-and-ceilings/drywall-installation-hanging/ - HomeGuide: https://homeguide.com/costs/drywall-repair-cost - USG: https://www.usg.com/content/dam/USG/pdpmovedocuments/sheetrock-gypsum-panels-installation-guide-en-J371.pdf ### How much does it cost to drywall a closet? Materials for a typical reach-in closet are a few sheets, a pail of compound and a roll of tape. Hired out, the price is usually the contractor's small-job minimum rather than a square-foot rate. Enter your quoted minimum and rate in the calculator above to see both. ### How many sheets of drywall for a closet? A 6 x 2.5 ft closet with 8 ft walls, inside faces and ceiling plus the room side of the door wall, takes the number of 4x8 sheets the calculator shows, laid out from the actual walls. ## Drywall for a 10x12 Room URL: https://drywallplanner.com/room-drywall/10x12 Summary: How many sheets of drywall a 10 x 12 ft room needs with 8, 9 or 10 ft walls, walls only or with the ceiling, in 4x8 or 4x12, laid out wall by wall. A 10 x 12 ft room with 8 ft walls, one door and one window takes 8 sheets of 4x12 drywall for the walls, or 11 sheets of 4x8. Add the 120 sq ft ceiling and it is 10 sheets of 4x12 or 15 of 4x8. With 9 ft walls the walls take 9 sheets of 4x12, and with 10 ft walls 10. Hung in 4x12 the 10x12 layout has 5 butt joints; in 4x8 it has 3 butt joints.

URL: https://drywallplanner.com/paint-calculator/12x12-room Summary: How much paint a 12x12 room needs: gallons for 8, 9 or 10 ft walls in one or two coats, the ceiling and primer for new drywall, net of doors and windows. A 12 x 12 ft room with 8 ft walls, one door and one window has 348 sq ft of wall to paint. Two coats at 350 sq ft per gallon is 2.0 gallons, so buy 2 gallons. One coat of a similar color is 1.0 gallons, so a single gallon covers it. The 144 sq ft ceiling takes another 0.8 gallons for two coats.

About 2.0 gallons for two coats on 8 ft walls, so 2 gallons, plus 0.8 gallons if you paint the ceiling too. With 9 ft walls it is 2.3 gallons. ### Is one gallon of paint enough for a 12x12 room? For one coat of a similar color on 8 ft walls, yes: it takes 1.0 gallons. For two coats, or with 9 ft walls, buy 2 gallons. ## Insulation for a 10x12 Shed URL: https://drywallplanner.com/shed-insulation/10x12 Summary: Insulation for a 10x12 shed counted bay by bay: batts and bags for walls, gables and roof at 16 or 24 in framing, with R-13 walls and R-13 or R-19 roof. A 10 x 12 ft shed with 7 ft walls framed 16 in on center has 31 stud bays once the 4 ft door is taken out, so the walls take 31 batts of R-13: 3 bags of Johns Manville 15 x 93 in kraft batts at 11 to a bag. Insulate the roof as well and add both gables and 18 rafter bays, for 4 bags of R-13 and 2 bags of R-19 in all. Counting by bay rather than by square foot matches how batts go in: one batt fills one bay, whatever its height. Article outline: - Why count bays instead of square feet - Insulating the roof of a shed Sources: - Johns Manville: https://www.jm.com/content/dam/jm/global/en/building-insulation/Files/BI%20Toolbox/JM%20Fiberglass%20Manufacturers%20Fact%20Sheet.pdf - Tuff Shed: https://www.tuffshed.com/products/sheds/premier-pro-series/premier-pro-ranch ### How many rolls of insulation for a 10x12 shed? Batts rather than rolls fit shed framing best. For 7 ft walls at 16 in framing, 3 bags of R-13 15 x 93 in batts for the walls; with the roof and gables, 4 bags of R-13 and 2 of R-19. ### What R-value for a shed? An unheated storage shed has no insulation minimum to meet; if you will heat or cool it as an office or studio, ask your building department what applies. In practice, R-13 fills 2x4 walls and R-13 or R-19 fills the roof, depending on rafter depth. ## Bathroom Drywall: Which Board Goes Where URL: https://drywallplanner.com/bathroom-drywall Summary: Can you put regular drywall in a bathroom? Pick a zone to see the board IRC Table R702.4.2 allows, then count tile backer and moisture resistant board. A bathroom takes two different products, and buying one where the code calls for the other is the most common bathroom drywall mistake. The tub and shower walls are a wet area and need a tile backer listed in the International Residential Code. The rest of the room, and the ceiling, can be moisture resistant gypsum board. This calculator measures each area separately so the order has the right amount of each. Article outline: - Can you put regular drywall in a bathroom? - Drywall above a shower - What goes behind tile in a tub or shower - The rest of the bathroom Sources: - International Code Council: https://codes.iccsafe.org/content/IRC2024P1/chapter-7-wall-covering - International Code Council: https://codes.iccsafe.org/content/IRC2024P1/chapter-3-building-planning - USG: https://assemblies-tools.usg.com/content/usgcom/en/products/walls/drywall/drywall-panels/lightweight-panels/sheetrock-ultralight-panels-mold-tough.143021.html ### Can I put regular drywall in a bathroom? Yes, outside the tub and shower area. The IRC allows regular board on bathroom walls and ceilings that do not get direct water, and it is an acceptable tile base for a vanity backsplash. Behind tile in a tub or shower it must be a listed backer instead. Moisture resistant board is a better buy in a steamy room even where it is not required. ### What drywall goes above a shower? Moisture and mold resistant drywall, from the top of the tile to the ceiling, in a normal bathroom with an exhaust fan. In a steam shower or a fully enclosed shower, run the tile backer and tile all the way to the ceiling instead. ### Can I use green board in a shower? Not behind tile in the tub or shower area under the 2024 IRC. Table R702.4.2 lists glass mat gypsum, fiber-reinforced gypsum, fiber-cement and cementitious backer units, and paper-faced water-resistant board is not one of them. Green board is fine on the rest of the bathroom walls and on the ceiling. ### How high does tile backer need to go in a shower? At least as high as the tile, and the code requires the nonabsorbent finish to reach at least 6 ft above the floor above a tub with a shower head and in a shower stall. Many people tile to the ceiling, in which case the backer goes to the ceiling too. ### Can moisture resistant drywall go on a bathroom ceiling? Yes. Section R702.3.7 of the 2024 IRC explicitly permits water-resistant gypsum backing board on ceilings. Over the shower itself, many installers use the same backer as the walls for extra margin. ## Paint Calculator URL: https://drywallplanner.com/paint-calculator Summary: Paint calculator for a room: gallons for walls and ceiling, net of doors and windows, by coats and can coverage (350 sq ft per gallon default), plus primer. Paint is bought by the can, so a paint estimate is really two questions: how many square feet are you covering, and how many whole containers does that turn into. This calculator measures the walls the same way the drywall calculator does, deducting doors, windows and any custom openings, then multiplies by the number of coats and divides by the coverage printed on the can. The result is rounded up to gallons and, where it is cheaper, five-gallon buckets. Article outline: - How much paint a room takes - New drywall needs primer first - One coat, two coats or three Sources: - Sherwin-Williams: https://www.sherwin-williams.com/en-us/color/color-tools/paint-calculator - Behr: https://images.homedepot-static.com/catalog/pdfImages/cf/cfd25499-d2a4-4d61-8961-c18a97caf60d.pdf - Benjamin Moore: https://www.benjaminmoore.com/en-us/product/regal-select-waterborne-interior-paint-matte-1-gallon/N548 ### How many gallons of paint for a 12 by 12 room? With 8 ft walls, one door and two windows, the walls are 384 sq ft gross and 333 sq ft net. Two coats at 350 sq ft per gallon is 1.9 gallons, so buy 2 gallons. The 144 sq ft ceiling takes another 0.8 gallon for two coats, so one more gallon of ceiling paint. ### Should I subtract doors and windows when calculating paint? Yes for walls you are rolling. The calculator deducts 21 sq ft per door and 15 sq ft per window. Paint for the doors and trim themselves is a separate, smaller purchase, usually a quart or a gallon of trim enamel. ### How much primer do I need for new drywall? One coat over every new surface. At 250 sq ft per gallon, a 14 by 12 room with 8 ft walls and a ceiling is about 533 sq ft, which is just over 2 gallons, so buy 3 gallons or check the coverage on your primer. ## Insulation Calculator URL: https://drywallplanner.com/insulation-calculator Summary: Insulation calculator: exterior wall and attic area from your room size, less openings, turned into bags of R-13 and R-19 batts by the bag coverage. Batt insulation is sold by the bag, and every bag lists the square feet it covers. The work is in getting the area right: only exterior walls need insulating, openings come out, and an attic often takes two layers to reach the R-value your code calls for. This calculator handles each of those, starting from the same room measurements as the drywall calculator. Article outline: - How the bag count is worked out - What R-value does the code ask for? - Insulate before the drywall goes up Sources: - Johns Manville: https://www.jm.com/content/dam/jm/global/en/building-insulation/Files/BI%20Toolbox/JM%20Fiberglass%20Manufacturers%20Fact%20Sheet.pdf - PNNL Building America Solution Center: https://basc.pnnl.gov/information/2009-2021-iecc-and-irc-minimum-insulation-requirements-new-homes - International Code Council: https://www.iccsafe.org/wp-content/uploads/IECC-RES-CAR-update-72622.pdf - ENERGY STAR: https://www.energystar.gov/saveathome/seal_insulate/identify-problems-you-want-fix/diy-checks-inspections/insulation-r-values ### How many bags of R-13 insulation do I need? Divide the exterior wall area by the coverage on the bag. A 14 by 12 room with 8 ft walls has 365 sq ft of net wall; if half of it is exterior wall, that is about 183 sq ft, or 2 bags of R-13 at 106.56 sq ft per bag. ### Can I stack batts in the attic? Yes. A second layer is usually unfaced and laid perpendicular to the first, across the joists, which also covers the joist tops. Two layers of R-19 give R-38. Set the layers field and the calculator multiplies the attic area accordingly. ### Do I deduct windows and doors from insulation? Yes, the openings are not insulated with batts. The calculator deducts the same 21 sq ft per door and 15 sq ft per window as the drywall calculator, plus any custom openings. ## Flooring Calculator URL: https://drywallplanner.com/flooring-calculator Summary: Flooring calculator for rectangular and L-shaped rooms: floor area, 10% to 20% waste by lay pattern, boxes to buy, baseboard length and optional cost. Flooring is sold in boxes that cover a fixed number of square feet, and the box is the only unit the store will sell you. That makes the estimate simple in principle: floor area, plus a waste allowance for cuts, divided by the coverage on the carton, rounded up. The waste allowance is where estimates go wrong, because it depends on how the floor is laid, not just how big the room is.

The floor is 144 sq ft; with 10% waste that is 158.4 sq ft. At 20 sq ft per box you need 8 boxes. A diagonal lay at 15% waste is 165.6 sq ft, which is 9 boxes. ### How much waste should I add for herringbone? Plan on about 20%. Every piece at the edge of a herringbone floor is cut at an angle, and the offcuts are rarely long enough to use elsewhere. ### Does the calculator include closets? Only if you include them in the measurements. Measure each closet as its own rectangle and add the area, or use the L-shape option when the closet makes the room an L. ## Tile Calculator URL: https://drywallplanner.com/tile-calculator Summary: Tile calculator: floor or wall area, tile size, grout joint and pattern give the tiles and boxes to buy, with 10% to 20% waste for cuts and breakage. Counting tiles is more exact than counting square feet, and a tile calculator should be too. Each tile covers its own face plus half of the grout joint around it, so a 12 x 24 in tile with a 1/8 in joint takes up a little more than 2 sq ft. Divide the area to tile by that footprint, add waste for cuts and breakage, and you have the number of tiles; divide by the count per box and you have the order. Article outline: - How the tile count is worked out - Picking a grout joint - Waste allowance for tile Sources: - Ceramic Tile Education Foundation: https://www.ceramictilefoundation.org/blog/want-credit-card-grout-joints-check-tile-industry-standards - Marazzi: https://digitalassets.daltile.com/content/dam/Marazzi/website/documents/content/MZ_Installing_Tile_web.pdf - Bob Vila: https://www.bobvila.com/articles/how-much-tile-do-i-need/ ### How many 12 x 24 tiles do I need for 100 sq ft? With a 1/8 in joint each tile covers about 2.02 sq ft. 100 sq ft plus 10% waste is 110 sq ft, which is 55 tiles. At 8 tiles per box, that is 7 boxes. ### Does grout joint width change how many tiles I need? A little. Each joint adds to the area a tile covers, so wider joints mean slightly fewer tiles. The effect is small on large tile and bigger on mosaics and small subway tile. ### Can I use this for a shower? Yes. Choose measured area, add up the width times height of each shower wall to the height you are tiling, and enter the total. In a shower the walls behind the tile need a listed backer board, not regular drywall; see the bathroom drywall calculator. ## How to Hang Drywall URL: https://drywallplanner.com/guides/how-to-hang-drywall Summary: How to hang drywall step by step: prep and blocking, a layout with fewer butt joints, ceiling-first order of work, screw depth and six mistakes to avoid. Hanging drywall is fast work with slow consequences. A sheet goes up in two minutes, but a joint in the wrong place, a screw set too deep or a gap at a corner will cost you an hour of finishing later. This guide covers the order of work, how to lay out sheets so you tape as little as possible, how to fasten correctly, and the handful of mistakes that separate a wall you prime once from a wall you keep coming back to. Article outline: - Before the first sheet goes up - Layout: fewer joints beats faster hanging - Hanging the sheets - Fastening: depth matters more than count - Six mistakes that create finishing work ### Should drywall be hung horizontally or vertically? Horizontally for most residential walls: it crosses more studs, puts the long tapered seam at a workable height, and produces fewer joints on a standard 8 ft wall. Vertical hanging is normal on steel-stud commercial work and where a wall is taller than the sheet is long. ### Do you hang the ceiling or the walls first? The ceiling first, always. Wall sheets then push up underneath and support the ceiling board edges, which makes that corner far easier to tape and stops the ceiling joint from cracking. ### How big a gap should I leave at the floor? About 1/2 in. It keeps the gypsum core away from floor moisture and gives you room to lever the sheet up tight against the board above. Baseboard covers it. ### Can one person hang drywall alone? Walls, yes, with a foot lifter for the bottom sheets. Ceilings, only with a drywall lift or T-braces. A 4x12 sheet of half inch board weighs about 77 lb, so a lift is not a luxury, it is the difference between a clean job and a damaged sheet. ### What screws do I need for drywall? Coarse-thread drywall screws for wood framing, fine-thread for steel studs. Use 1-1/4 in for half inch board and 1-5/8 in for five eighths inch board. Do not substitute deck or wood screws: the heads are the wrong shape and they tear the paper. ## Drywall Thickness Guide URL: https://drywallplanner.com/guides/drywall-thickness Summary: Drywall thickness guide: where 1/4, 3/8, 1/2 and 5/8 in board belong, ceiling sag at 24 in joist spacing, type X fire ratings and sheet weights. Drywall comes in four common thicknesses, and picking the wrong one is one of the few drywall mistakes you cannot fix with more compound. Half inch board on a ceiling with 24 in joist spacing will sag. Standard board in a shower surround will fail. Board that is too thin to meet a fire rating will not pass inspection. This guide covers what each thickness is for, what it weighs, and where code is likely to have an opinion. Article outline: - The four thicknesses and what they are for - Ceilings: where thickness actually matters - Fire ratings and where code has an opinion - Does thickness change your estimate? ### Is 1/2 in or 5/8 in drywall better for ceilings? Five eighths inch is the safer choice and is normally required at 24 in joist spacing. At 16 in spacing half inch is acceptable, and half inch sag resistant board is a good middle option that weighs noticeably less than five eighths. ### What thickness of drywall is standard for walls? Half inch is the residential standard for interior walls in North America. Three eighths inch board turns up in older houses, and quarter inch is only a resurfacing or curved-wall material. ### Do I need type X drywall in my garage? It depends on the surface and your adopted code. The 2024 IRC model code calls for at least 1/2 in gypsum board on the garage side adjoining a dwelling or attic, and at least 5/8 in type X or equivalent below the dwelling. Confirm the local requirement before ordering. ### How much does a sheet of drywall weigh? About 51 lb for a 4x8 sheet of half inch, 77 lb for a 4x12 of half inch, and about 106 lb for a 4x12 of five eighths type X, by USG's published weights. Lightweight half inch board runs about a fifth lighter than standard. ### Can I use 1/4 in drywall on a wall? Only as a skin over an existing sound wall, or to form a gentle curve. It has no useful strength on open framing and will not meet any fire or impact requirement on its own. ## Types of Drywall URL: https://drywallplanner.com/guides/drywall-types Summary: Types of drywall compared: standard, moisture and mold resistant, type X fire rated, sound damping and abuse resistant board, and where each is worth it. Walk the drywall aisle and you will find white, green, purple, blue and gray board, all roughly the same size and all priced very differently. The color is a manufacturer convention rather than a standard, but the categories behind them are real: moisture resistance, mold resistance, fire resistance, sound damping and impact resistance. This guide explains what each type is actually for, so you buy specialty board where it earns its price and standard board everywhere else. Article outline: - Standard board, and why it is usually the right answer - Moisture and mold resistant board - Fire, sound and impact board - How specialty board changes your estimate ### What is green board drywall used for? Damp rooms where the surface will not get direct water: bathroom walls away from the shower, laundries and basements. It is moisture resistant, not waterproof, and should not be used as a tile backer inside a shower or tub surround. ### Is purple drywall better than green? For humid rooms, generally yes. Purple-branded board typically adds mold resistance on top of moisture resistance, usually with a coated or fiberglass facing that gives mold nothing organic to grow on. It costs more, so it earns its place in bathrooms rather than throughout a house. ### What is type X drywall? Type X is commonly a five eighths inch fire-resistant panel with glass fibers in its gypsum core. It is used as one component of tested fire-rated assemblies, so the complete listed build-up and local code control. ### Does soundproof drywall actually work? Yes, but only as part of a properly detailed assembly. A damping panel on a wall with no insulation, rigid framing contact and unsealed electrical boxes will underperform badly. Seal the flanking paths and address the framing first, then add the panel. ### Can I mix drywall types in one room? Yes, and it is normal: a tile backer in the shower, mold resistant board on the rest of the bathroom walls, standard board elsewhere. Just keep the same thickness on any single plane, since a step between sheets is very hard to hide. ## How to Cut Drywall URL: https://drywallplanner.com/guides/how-to-cut-drywall Summary: How to cut drywall with a knife, not a saw: the four cuts you will make, from score and snap to outlet openings and curves, with clean edges and less dust. Almost all drywall cutting is done with a knife, not a saw. Gypsum board is two sheets of paper with a brittle core between them, so the technique is to cut the paper and let the core snap along the line. Understanding that one fact turns cutting drywall from dusty, awkward work into something quiet and quick. This guide covers the four cuts you will actually make and how to keep the edges clean enough to finish. Article outline: - The score and snap: straight cuts - Outlets, switches and boxes - Curves, notches and awkward shapes - Dust, blades and offcuts ### What is the best tool for cutting drywall? A sharp utility knife and a drywall T-square handle most cuts. Add a jab saw for openings, a rasp to dress edges, and a drywall router if you are cutting many boxes. A circular saw is rarely the right answer indoors: it is loud and creates a lot of dust for no benefit. ### Do you cut drywall face up or face down? Face up. Score the face paper, snap the core, then cut the back paper. That way the clean scored edge is on the visible side and any tearing ends up on the back. ### How do you cut a hole for an electrical outlet? Either measure from two fixed references and cut with a jab saw before hanging, or tack the sheet over the box and ride a drywall router around the box edge. Cut to the box edge, not around it, since a cover plate only hides about 1/8 in of overcut. ### Can you bend drywall around a curve? Yes. Quarter inch board bends readily and becomes more willing if you lightly dampen the face paper and let it rest a few minutes. For tighter radii, score the back paper in close parallel kerfs so the core can hinge, and support the board fully behind. ### Is drywall dust dangerous? Gypsum dust is a respiratory irritant and some products contain silica, so wear a fitted N95 or P2 mask whenever you saw, rout or sand. Scoring with a knife produces very little dust, which is a good reason to use it wherever possible. ## How to Tape Drywall Joints URL: https://drywallplanner.com/guides/how-to-tape-drywall-joints Summary: How to tape drywall joints: paper vs mesh tape, setting vs all-purpose compound, the three coats, inside and outside corners, and how to sand less. Taping is where a drywall job is won or lost. Hanging is measured in hours, taping in days, and every shortcut shows up under paint. The good news is that the process is completely standard: reinforce every joint with tape bedded in compound, then build the joint out in two or three progressively wider coats, then sand as little as you can get away with. This guide covers the materials, the coats, and how to keep sanding to a minimum. Article outline: - Paper tape, mesh tape and which compound - The three coats - Inside and outside corners - Sanding less, and knowing when to stop ### How many coats of joint compound do drywall joints need? Three is standard for a level 4 finish: a tape coat, a fill coat and a finish coat, each thinner and wider than the last. A level 5 finish adds a skim over the whole surface, which is worth it under gloss paint or strong raking light. ### Is mesh tape or paper tape better? Paper tape is stronger and resists cracking better, and it is the right choice for flat joints and all inside corners. Self-adhesive mesh is faster and convenient for patches, but it should be used with a setting-type compound because it is weaker in tension. ### How much joint compound do I need? Budget about 140 lb of all-purpose compound per 1,000 sq ft of board for taping plus two finish coats, which is roughly one 4.5 gallon box per 440 sq ft. Our calculator converts your board total into both pounds and boxes. ### How long should compound dry between coats? Ready-mixed compound typically needs 12 to 24 hours per coat, and longer in a cold or humid room. Setting-type compound cures on its labeled schedule, from 20 to 90 minutes, regardless of humidity. Never coat over compound that is still dark or cool to the touch. ### Why can I still see the joints after painting? Almost always one of three things: the joint was not feathered wide enough, especially a butt joint; sanding scratched through the paper facing; or the wall was painted without primer, so the compound and paper absorbed the paint differently. ## Drywall Finish Levels Explained URL: https://drywallplanner.com/guides/drywall-finish-levels Summary: Drywall finish levels 0 to 5 explained: which level your room needs by paint sheen and lighting, what a level 5 skim involves, and what each level costs. Drywall finish levels are a real industry standard, not marketing language. Levels 0 through 5 describe exactly how much taping and coating a surface has received, and they exist so a specification can say what a wall should look like without ambiguity. Knowing them is useful for two reasons: you can ask a contractor what is actually included in a quote, and you can stop over-finishing surfaces that nobody will ever see. Article outline: - The six levels - Which level does your room need? - What a level 5 finish actually involves - What each level costs ### What is the difference between level 4 and level 5 drywall finish? Level 4 is three coats over the joints and fasteners, with tool marks removed. Level 5 adds a thin skim coat of compound over the entire surface, which equalizes texture and porosity. Level 4 suits flat paint in ordinary light; level 5 is for gloss paint and walls that take raking light. ### Do I need a level 5 finish? Only if the wall will take semi-gloss or gloss paint, or strong side lighting from a window or wall washer. For flat-painted walls in normal lighting a careful level 4 is indistinguishable and costs meaningfully less. ### What finish level goes behind tile? Level 2 is sufficient: tape embedded, one coat over it, fasteners covered. A smoother finish is wasted under thinset. In a wet area, use a proper tile backer rather than drywall in the first place. ### Is a primer-surfacer the same as a level 5 finish? No, though it is a genuine improvement over plain primer. A high-build primer-surfacer fills fine texture but does not equalize the surface the way a compound skim does. On a long, side-lit wall the difference is visible. ### How much does level 5 finishing add to the cost? Typically 20% to 30% on top of the finishing labor, and more on large ceilings where the work is overhead. Materials add very little; it is almost entirely labor. ## Drywall Screw Spacing URL: https://drywallplanner.com/guides/drywall-screw-spacing Summary: Drywall screw spacing: about 16 in on walls and 12 in on ceilings, 3/8 in from edges, plus screws per sheet, correct depth, and screws vs nails and adhesive. Screw spacing is one of the few drywall numbers that is genuinely prescriptive: codes and manufacturer instructions state maximum spacings, and rated assemblies are tested at specific patterns. It is also one of the most commonly overdone jobs on site, because more screws feels safer than fewer. It usually is not. This guide covers the standard spacings, how many screws a sheet actually needs, and why fastener depth matters more than fastener count. Article outline: - Standard spacings - How many screws per sheet? - Depth is what actually matters - Screws, nails and adhesive ### How far apart should drywall screws be? Common manufacturer guidance for non-fire-rated screw-only work is up to about 16 in on center on walls and 12 in on center on ceilings, keeping fasteners 3/8 in back from sheet edges. Local code and the board manufacturer instructions govern, and rated assemblies must follow their tested pattern exactly. ### How many screws per sheet of drywall? A 4x8 sheet across studs 16 in on center takes 28 screws on a wall and 35 on a ceiling; a 4x12 takes 40 and 50. Buy about one per square foot on walls and 1.25 on ceilings, 32 and 40 per 4x8 sheet, to cover drops and misses. ### How deep should a drywall screw be set? Just below the surface, in a dimple you can feel with a taping knife but that has not torn the face paper. A screw driven through the paper holds almost nothing, and overdriving is the main cause of fastener pops appearing later. ### Can you use nails instead of drywall screws? Nails are still permitted in many jurisdictions, but screws are better: they hold far better in withdrawal, they can be backed out and reset, and they involve no hammer blows that could fracture the core. Almost no new work uses nails alone. ### How many pounds of drywall screws do I need? Around 320 screws to the pound for 1-1/4 in coarse thread, so one pound covers roughly ten 4x8 wall sheets. Buy 10% to 15% over your calculated count to cover misses and strips. ## How to Patch Drywall URL: https://drywallplanner.com/guides/how-to-patch-drywall Summary: How to patch drywall by hole size: nail holes and fastener pops, holes up to 6 in with a mesh patch, larger holes cut back to studs, plus water damage. Drywall repair is sized by the hole. A nail hole needs a swipe of compound. A doorknob hole needs a patch with something behind it. A hole bigger than your hand needs a piece of board and a stud to screw it to. Get the category right and every one of these is a straightforward job; get it wrong and you either waste an afternoon on a nail hole or watch a large patch crack out within a year. Article outline: - Nail holes and small dents, up to about 1/2 in - Holes up to about 6 in: mesh or a patch kit - Larger holes: cut back to the studs - Water damage, corners and recurring cracks ### What is the best filler for small drywall holes? Lightweight joint compound or a spackling product, applied in two thin coats. Press it into the hole rather than smearing it across, scrape flush immediately, and expect slight shrinkage that the second coat handles. ### How do you fix a doorknob hole in drywall? Trim the loose paper back, cover the hole with a self-adhesive mesh patch or metal patch plate, then bed it with setting-type compound about 8 in wide. Add two progressively wider coats of all-purpose compound, feather the edges, sand lightly and prime. ### How big a hole can you patch without cutting back to studs? Roughly up to a hand-sized opening, using a mesh or metal-backed patch. Beyond that, cut the hole back to a rectangle with its vertical edges on stud centers, add backers if needed, and screw in a piece of matching board. ### Why does the same crack keep coming back? Because it is movement, not a filling failure. Common causes are seasonal truss lift, a butt joint landing on the corner of a door or window opening, or a missing expansion detail. Fix the cause or add a proper movement joint, otherwise the same crack will return. ### Can I paint over water-stained drywall? Only after the leak is fixed and everything is fully dry, and only with a stain-blocking primer. Water-based primer alone lets the stain bleed back through. Board that is soft or crumbling has to be cut out rather than coated. ## Drywall Tools Checklist URL: https://drywallplanner.com/guides/drywall-tools Summary: Drywall tools checklist for measuring, cutting, hanging, taping and cleanup: what to buy, when to rent a lift at about $40 to $60 a day, and what to skip. Drywall is a cheap material and a labor-heavy job, which means the right tools pay for themselves within one room. It also means the aisle is full of things you do not need. This list separates what genuinely changes the outcome from what is optional, and calls out the two items worth renting rather than buying. Article outline: - Measuring and cutting - Hanging and lifting - Taping and finishing - Safety and cleanup ### What tools do I need to hang drywall? At minimum: a utility knife with spare blades, a 48 in drywall T-square, a tape measure, a jab saw, a rasp, a stud finder, and a screw gun with a depth-setting nose. For ceilings, add a rented drywall lift. ### Should I rent a drywall lift? Yes for any ceiling work. At roughly $40 to $60 a day it is the highest-value rental in the job, it makes single-person ceiling hanging possible, and the seams come out visibly better than sheets held up by hand. ### What size taping knives do I need? Three: 5 or 6 in for the tape coat, 8 to 10 in for the fill coat, and 10 to 12 in for the finish coat. Each coat has to be wider than the last, so the progression of widths is what makes joints disappear. ### Do I need a drywall router? Only if you are cutting a lot of outlet boxes. It is much faster in place, but a jab saw and accurate measuring handle a single room perfectly well. It starts to pay off from several rooms upward. ### How do I keep drywall dust under control? Score and snap rather than sawing wherever possible, seal doorways with plastic sheeting, wet sand with a damp sponge instead of dry sanding, and use a shop vacuum with a fine dust filter. Always wear a fitted N95 or P2 respirator when sanding. ## Basement Ceiling Drywall Code URL: https://drywallplanner.com/guides/basement-ceiling-drywall-code Summary: Does a basement ceiling need drywall? IRC R302.13 floor protection, its five exceptions such as 2x10 joists, 1/2 vs 5/8 in board and foam thermal barriers. Whether a basement ceiling needs drywall is one of the most argued questions in home building, and the answer is in one short section of the International Residential Code. R302.13 requires floor assemblies above a basement to have at least a 1/2 in gypsum wallboard membrane, or 5/8 in wood structural panel or equivalent, on the underside of the floor framing, unless one of five exceptions applies. The most important exception covers floors framed with 2x10 or larger dimension lumber or structural composite lumber, which is why many basements with open joists need nothing more, while floors framed another way usually need the membrane. Article outline: - What R302.13 requires - The exceptions - 1/2 or 5/8 in on a basement ceiling? - Foam insulation on basement walls - Under the basement stair ### Does a basement ceiling need drywall by code? Under IRC R302.13, the floor above a basement needs at least a 1/2 in gypsum wallboard membrane on its underside unless an exception applies: sprinklers, a crawl space with no storage or heating appliances, up to 80 sq ft of fireblocked unprotected area, or framing of 2x10 or larger dimension lumber or structural composite lumber. ### Does a basement ceiling need 5/8 drywall? Not for R302.13, which asks for 1/2 in gypsum wallboard. Use 5/8 in where the framing or a texture calls for it, such as 24 in joists with a water-based spray texture, or where your local code requires more. ### Can I leave my basement ceiling unfinished? If the floor is framed with 2x10 or larger dimension lumber or structural composite lumber, or the basement is sprinklered, the model code allows it. Other framing, including many engineered floor systems, needs the membrane. Confirm with your building department. ### Do recessed lights and access panels break the code membrane? No. R302.13 explicitly permits penetrations and openings for ducts, vents, outlets, lighting, wires, speakers, drainage, piping and similar items. ## Drywall Bundles, Lifts and Delivery URL: https://drywallplanner.com/guides/drywall-bundle-pallet Summary: How drywall ships: two sheets to a bundle, what bundles and stacks weigh, boom truck delivery, and how to stack board without overloading a floor. Drywall is bought by the sheet but ships by the bundle: two sheets taped together at the ends. Bundles are stacked into units, often called lifts, that a forklift or a boom truck moves in one pick. This guide covers what the manufacturers publish about bundles, what a bundle and a stack weigh, how delivery works, and how to stack and store board so it does not sag, crack or overload a floor. Article outline: - What is in a bundle of drywall - How much a bundle of drywall weighs - Units, lifts and pallets - How drywall delivery works - Stacking board inside the house - Storing drywall until it goes up ### How many sheets of drywall are in a bundle? Two. USG, Georgia-Pacific and CertainTeed all package gypsum board two sheets to a bundle, and Georgia-Pacific and CertainTeed describe the pair as face to face and taped at the ends. ### How much does a bundle of drywall weigh? About 102 lb for two sheets of regular 1/2 in 4x8 board and 80 lb for lightweight 1/2 in, by USG's published weights. A bundle of 5/8 in type X in 4x12 is about 211 lb. ### How many sheets of drywall are on a pallet or lift? There is no standard count. The manufacturer documents checked for this guide publish the two-sheet bundle but not a sheet count per unit, so ask your supplier how many sheets their lifts hold for the board you are buying. ### Can drywall be stored outside or in a garage? Not outside: the Gypsum Association says gypsum panels should not be stored outdoors. A dry, enclosed garage can work if the board lies flat on risers, stays out of direct sun and does not sit above 125°F for long. ## Drywall for a Mobile Home URL: https://drywallplanner.com/guides/mobile-home-drywall Summary: Drywall for a mobile home: what the HUD code says about interior finish, panel thickness and weight on light framing, low walls and how to estimate sheets. Manufactured homes are built to the federal HUD code, not the IRC, and their interiors are different from a site-built house: lighter framing, lower walls, and panels that were often vinyl-covered gypsum held in place by battens rather than taped drywall. Putting drywall in a mobile home is common, especially when replacing water-damaged or dated vinyl panels, but the board you choose has to suit framing that was designed around thinner, lighter panels. Article outline: - What the HUD code says about interior finish - What thickness drywall for a mobile home? - Wall heights and estimating ### What thickness drywall is used in mobile homes? From 5/16 to 1/2 in, according to Clayton Homes: 5/16 in was historically common for vinyl- and paper-faced panels, 3/8 in is now typical for those, and finished drywall is 3/8 or 1/2 in. ### Can you put regular drywall in a mobile home? Yes, and it is a common upgrade. The HUD code limits flame spread rather than thickness, and gypsum board meets those limits. Prefer lightweight 1/2 in board on light framing and ceilings, and check that the studs can carry it. ### How tall are mobile home walls? Many older homes have 7 ft walls; newer homes are often 90 in or 8 ft. The HUD code requires at least a 7 ft ceiling over at least half of each habitable room. ## Home Improvement Calculators URL: https://drywallplanner.com/calculators Summary: Free home improvement calculators on one room engine: drywall sheets and layout, paint, insulation, flooring and tile, each one embeddable on your site.
