Find how many drywall sheets cover a wall or ceiling.
Dividing the total wall area including waste by the area of a single sheet, rounded up, gives the number of full sheets to order. Drywall is sold in full sheets and is wasteful to cut, so counting whole sheets prevents over- or under-ordering.
Drywall Sheets
Sheets = area x (1 + waste) / (sheet length x height)
Sheets = area x (1 + waste) / (sheet length x height) Dividing the total wall area including waste by the area of a single sheet, rounded up, gives the number of full sheets to order.

This calculator takes 4 inputs: Area to cover, Sheet length, Sheet height, Waste allowance. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
