What this drywall sheet calculator calculates
A 1,200 ft² covered area needs 38 4 × 8 sheets before waste because each cited panel covers 32 ft².
Formula
Covered wall and ceiling area ÷ 32 ft² per 4 × 8 sheet × (1 + waste) = sheets, rounded up.
Worked example
At 10% waste, 1,200 ft² becomes 1,320 planned ft². Dividing by 32 gives 42 sheets.
Ordering decision
Sheet orientation, ceiling height, openings, fire rating, thickness, and the panel's actual dimensions change the takeoff.
