Estimate drywall sheets, screws, joint compound, and tape from your total wall and ceiling area.
Estimates for planning only. Always confirm measurements and order a little extra for waste and cuts.
This calculator turns your total wall and ceiling area into the number of drywall sheets, plus the screws, joint compound, and tape to finish the job.
Sheet count is your area plus waste, divided by the coverage of your chosen sheet size:
Sheets = area × (1 + waste %) ÷ sheet coverage
A 4×8 sheet covers 32 sq ft; 4×12 covers 48 sq ft.
Plan about 36 screws per sheet, plus joint compound and tape for every seam.
Bigger 4×12 sheets mean fewer seams to tape and a smoother finish, but they're heavy and awkward in tight spaces. Use 4×8 for small rooms and stairwells. Budget roughly one screw every 12 inches on edges and 16 inches in the field (about 36 per sheet), a tube or box of joint compound per ~100-150 sq ft, and joint tape for every seam plus inside corners.
Enter the total wall and ceiling area you need to cover, then pick a sheet size. The tool divides your area, plus a waste allowance, by the coverage of one sheet and rounds up to whole sheets. A 4 by 8 sheet covers 32 square feet, a 4 by 10 covers 40, and a 4 by 12 covers 48. From that sheet count it estimates the screws, joint compound, and joint tape needed to hang and finish the job. Enter an optional price per sheet and it multiplies through to a materials-only cost for the drywall itself.
The finishing quantities follow standard drywall rules of thumb, not our own data: roughly 36 screws per sheet, about one every 12 inches on the edges and 16 inches in the field, plus a joint compound allowance and joint tape footage scaled to your square footage, with tape planned for every seam and inside corner. The default waste allowance is 10 percent, which you can raise for rooms with many outlet, window, and door cutouts.
This is a planning estimate for the main materials, not a complete order list. Corner bead, specialty fasteners, texture, primer, and labor are not in it, and rounding up sheets can leave you with a spare or two. Confirm your measurements before you buy, and order a little long for cuts and mistakes. We build lead-capturing calculators like this one for contractors, from $600.
The tool defaults to 10 percent. Raise it toward 15 percent for rooms with a lot of cutouts for outlets, windows, and doors, or many short walls that force extra cuts. A simple rectangular room with few openings can stay near 10 percent. Whatever you pick, round the sheet count up and keep a spare on hand.
Not the whole job. If you enter a price per sheet, the tool multiplies it by the sheet count for a materials estimate on the drywall itself. That figure leaves out labor, screws, compound, tape, corner bead, and texture, so it is only part of the total. For installed pricing, get quotes from local drywall contractors.
