How does the drywall calculator work?
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.
What else do people ask about this calculator?
What kind of drywall in a bathroom?
Cement board or a waterproof foam board in the shower/tub surround, moisture-resistant (paperless or 'purple') drywall on other bathroom walls, and standard or moisture-resistant drywall on the ceiling.
Can I use regular drywall in a bathroom?
Only on walls that stay dry and on the ceiling — and only if the bathroom has a working exhaust fan. Never use standard drywall behind tile or anywhere it may get splashed.
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.
