Drywall Sheets
Find how many drywall sheets cover a wall or ceiling.
About Drywall Sheets
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.
Formula
Drywall Sheets
Sheets = area x (1 + waste) / (sheet length x height)
- waste
- Cutting and fitting allowance
