Wall area in, a full drywall order out — sheets, mud, tape, screws, and the installed price. Then send it straight into a quote.
Ballpark, not gospel. This estimates drywall materials and installed cost from your dimensions — texture level and corner count are what move real drywall jobs, so price those before quoting.
Straight answers, no fluff. Then run your own numbers above.
Divide your wall area (minus doors and windows at ~21 sq ft each) by the sheet size — 32 sq ft for a 4×8, 48 for a 4×12 — and round up. A 16×12 room with 8-foot ceilings and the ceiling included needs about 27 4×8 sheets. The calculator above handles the whole count.
Hang + finish runs $1.75–$2.75 per square foot installed in 2026 — materials are a small slice, roughly $12–$18 per sheet plus mud and tape. Texture level, corners, and patches move the rate.
Budget roughly one 5-gallon bucket per 6 sheets for a standard hang-and-finish job, plus one 500-foot tape roll per 12 sheets. Smooth level-5 finishes can double the compound.
4×12 sheets mean fewer seams and a faster finish — but they need two people and a truck. Solo crews and DIY jobs should stick with 4×8.
