To finish it
Both gable triangles are cut from one panel the width of the shed and as tall as the gable, so they show as one surface. Add a spare sheet for a small job like this.
4x8, 4x10 or 4x12 for a 10 x 12 shed
| Board | Sheets | Butt joints | Taped seams | Offcut waste | Labor, national range |
|---|---|---|---|---|---|
| 4x8 | 17 | 5 | 98 ft | 21.7% | $511 to $1,065 |
| 4x10 | 13 | 8 | 88 ft | 18.0% | $511 to $1,065 |
| 4x12 (fewest joints) | 11 | 4 | 73 ft | 19.3% | $511 to $1,065 |
A 10 x 12 ft shed with 7 ft walls, a 4 x 6.5 ft door and one window takes about 11 sheets of 4x8 drywall for the walls alone, 15 with a flat ceiling at wall height, and 17 if you board the gable ends and the underside of a 6 in 12 roof for a vaulted ceiling. That vaulted build has 5 butt joints in 4x8 and 4 butt joints in 4x12.
Flat ceiling or vaulted in a 10x12 shed?
A flat ceiling at wall height is the least board, 120 sq ft for this shed, and leaves the attic space for storage or insulation. A vaulted ceiling follows the roof: it takes the two roof slopes, 134 sq ft at 6 in 12, plus the two gable triangles, 25 sq ft together. That is 2 more sheets of 4x8 than the flat version, 17 against 15.
Surface by surface: the vaulted 10x12 shed in 4x8
- Door wall, 10 by 7 ft, with the door opening: hung vertically, 3 pieces cut from 3 sheets, no butt joints, 14 ft of taped seam.
- Side wall, 12 by 7 ft, with the window: hung vertically, 3 pieces cut from 3 sheets, no butt joints, 14 ft of taped seam.
- Back wall, 10 by 7 ft: hung vertically, 3 pieces cut from 3 sheets, no butt joints, 14 ft of taped seam.
- Side wall, 12 by 7 ft: hung vertically, 3 pieces cut from 3 sheets, no butt joints, 14 ft of taped seam.
- Ceiling slope, 12 by 5.6 ft: hung horizontally, 5 pieces cut from 3 sheets, 3 butt joints, 19 ft of taped seam.
- Ceiling slope, 12 by 5.6 ft: hung horizontally, 4 pieces cut from 3 sheets, 2 butt joints, 18 ft of taped seam.
- Both gable ends, 10 by 2.5 ft: hung vertically, 3 pieces cut from 2 sheets, no butt joints, 5 ft of taped seam.
On 7 ft walls the 4x8 layout stands the sheets up and trims each one 1 ft short, which leaves no horizontal seam at all. Each gable end is a 10 ft wide triangle rising 2.5 ft to the ridge; cut one out of a rectangle and the corner offcuts make the other, so both together are one 10 by 2.5 ft panel, 3 pieces of board in this layout.
In 4x12 board the same shed takes 11 sheets with 73 ft of taped seam, against 17 sheets and 98 ft in 4x8. 4x12 comes out ahead on both sheets (11) and butt joints (4).
Labor for a 10x12 shed
Walls, gables and roof slopes put 426 sq ft of board up after the door and window. At the national planning range of $1.20 to $2.50 per sq ft to hang and finish, a contractor would charge roughly $511 to $1,065 in labor for the vaulted 10x12 build.
Hanging drywall in a 10x12 shed
- Hang the 134 sq ft of roof slope first, then the gables, then the 267 sq ft of wall, so wall board supports the ceiling edges.
- Insulate the 7 ft walls and the roof before any board goes up. A shed with drywall and no insulation or vapor control can trap moisture behind the board.
- Add a spare: 18 sheets of 4x8 covers the vaulted layout with one to spare for a miscut.
