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 thickness drywall in a basement?

Use ½ in standard drywall on walls and ⅝ in fire-rated (Type X) drywall on the ceiling if it's under a wood-framed floor — required by most residential building codes.

Do I need moisture-resistant drywall in a basement?

Yes on any wall touching a foundation or exterior wall — paperless (fiberglass-faced) or purple mold-resistant drywall is standard. Interior partition walls can use regular drywall.

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.
