# 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](https://studsheet.com/sheets/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](https://studsheet.com/sheets/patch)**: nail holes, dents, doorknob holes and bigger cut-outs, with the compound, patches and primer.
- **[Finish a basement](https://studsheet.com/sheets/basement)** and **[build an interior wall](https://studsheet.com/sheets/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](https://studsheet.com/sheets/drywall) 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?

Yes. “Send to the yard” sends the job’s materials to your supply house as a quote request, grouped the way they pick it.
