Divide the total square footage by the sheet size (32 sq ft for 4×8, 48 sq ft for 4×12), add about 10% for waste, and round up. The calculator above does this for you.
A 12×12 room with 8 ft ceilings has about 384 sq ft of wall. With 4×8 sheets (32 sq ft) plus 10% waste that's roughly 14 sheets for the walls, or about 18 if you include the ceiling. Enter your exact numbers above for a precise estimate.
A rough rule is about 1 gallon of all-purpose compound and roughly 0.75 linear feet of tape per square foot of drywall for a standard three-coat finish. The calculator estimates both from your room size.
4×12 sheets cover more area with fewer seams — a smoother finish and less taping — but they're heavier and harder to handle in tight spaces. 4×8 sheets are easier for DIY and small rooms. The calculator supports both.
