How the drywall calculator works
Add wall + ceiling area, divide by sheet coverage (a 4×8 sheet = 32 ft²) to get sheets. Estimate roughly 1 screw per ft², one 3.5-gallon bucket of joint compound per 400 ft², and 0.5 ft of tape per ft² of drywall.
Frequently asked questions
How many drywall sheets do I need?
Divide total wall + ceiling area by 32 ft² (for 4×8 sheets) or 48 ft² (for 4×12 sheets). Add 10% for cuts.
How many screws per drywall sheet?
About 32 screws per 4×8 sheet — 8 in on ceilings, 12 in on walls along studs.
