Drywall Calculator
Estimate the drywall sheets needed from the area, sheet dimensions, and waste allowance.
Sheets needed for an area
Calculate wall area from width and height or enter a known area. Openings are subtracted before dividing by sheet area, and waste is applied before the final ceiling.
Sheets = ceiling((area × (1 + waste)) ÷ sheet area)
Scope of the estimate
This calculates sheets, not studs, screws, tape, or compound, whose quantities depend on the wall system and manufacturer. Sheetrock is a commercial term in some markets, not a Utilsha affiliation.
