Every sheet, bucket and screw. Counted.
Type the room or the wall runs. StudSheet lays out the board wall by wall in 4×8, 4×10 or 4×12 sheets, counts the joint compound, tape, corner bead and screws with the math shown, prices it at your rates, and turns it into an estimate your client signs on their phone.
The drywall Sheets
- Hang and finish drywall: a room or wall runs, in regular, lightweight or moisture-resistant ½″, ⅝″ Type X or abuse-resistant board, hung across the studs or up and down, finished to the level you choose.
- Patch a hole in drywall: nail holes, dents, doorknob holes and bigger cut-outs, with the compound, patches and primer.
- Finish a basement and build an interior wall: framing, insulation and drywall on one Sheet.
From the drywall Sheet: 14′ × 12′ room
14′ × 12′ room: 21 sheets (4×8) for 533 sq ft of walls and ceiling, 2 pails of joint compound, and the tape and screws.
| Buy | Item | How StudSheet counts it |
|---|---|---|
| 15 sheets | Drywall ½″ | Walls, laid out wall by wall: 4 walls (2 × 14′ and 2 × 12′), 2 rows across the studs: 8 full + 6 cut for the row ends = 14. Offcuts are reused where they fit; doors and windows are cut out of full sheets. + 1 spare for breakage (about 5%). Covers 365 sq ft. |
| 6 sheets | Lightweight drywall ½″ | Ceiling: 3 rows across the joists, 14′ long: 3 full + 3 cut for the row ends = 6. Covers 168 sq ft. |
| ≈693 screws (3 lb) | Drywall screws, coarse thread | 15 wall sheets × 28 (one every 16″ on each stud) + 6 ceiling sheets × 35 (one every 12″ on each joist) + 10% for drops and strips. ½″ board takes 1¼″ screws — at least ⅝″ into the wood (IRC R702.3.6). About 250 per lb. |
| 2 pails | All-purpose joint compound | 533 sq ft of board × 10 gal per 1,000 sq ft for Level 4 (tape + 2 coats) = 5.3 gal (USG: about 9.4–10 gal per 1,000 sq ft for a three-coat job). |
| 1 roll | Paper joint tape | 197 ft: about 370 ft per 1,000 sq ft of board (USG), seams and inside corners. |

How the Sheet counts
- The board: laid out wall by wall, with doors and windows cut out of full sheets and offcuts reused where they fit, not square feet divided by 32.
- Joint compound: about 10 gallons per 1,000 sq ft of board for a Level 4 finish (USG’s figure), less for a lower level.
- Tape, bead and screws: from the seams, the outside corners and the sheet count.
Questions
How many sheets of drywall for a 12×14 room?
A 12′ × 14′ room with 8′ ceilings has 416 sq ft of walls and 168 sq ft of ceiling. Square feet ÷ 32 plus 10% says about 21 sheets, and so does StudSheet, but it gets there by laying the board out wall by wall: 15 sheets for the walls (8 full and the cut row ends, offcuts reused where they fit) and 6 lightweight sheets for the ceiling, with doors and windows cut out of full sheets. Open the drywall Sheet for your room.
How much joint compound do I need?
About 10 gallons per 1,000 sq ft of board for a Level 4 finish: tape and two coats. The 12′ × 14′ room has about 533 sq ft of board once the openings are taken out, so 2 pails. Tape follows every seam and inside corner. The drywall Sheet counts both from its layout.
Can I send the material list to my supply yard?
