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.

The page cites the applicable Uzi Tools reference table beside the calculator. Product labels, current editions, local code, and a licensed professional govern structural, electrical, and life-safety work.
