Drywall calculator

How it works

Sheet count is the area to cover divided by the area of one sheet, plus a waste allowance for cuts. Partition walls are covered on both faces, which doubles the area. Screws, tape and compound use typical per-area averages.

How to measure

Measure total wall length and ceiling height. Enter door and window openings separately as width × height.

Tips

• Use moisture-resistant board in bathrooms and fire-rated board where code requires it.
• Joints must land on studs; stagger them between rows.
• Set screw heads just below the surface without tearing the paper.
