Drywall Calculator
Calculate drywall sheets required for walls, ceilings, remodeling, and construction projects.

Drywall Calculation Formula
Drywall sheets are estimated by dividing the total wall area by the coverage area of one drywall sheet.
Drywall Sheets = Wall Area ÷ Sheet Area
Always round the result up to the next whole sheet because drywall cannot be purchased in fractions.
