Enter room length, width and wall height in feet. Wall area = 2 × (length + width) × height; add the ceiling if you are drywalling it. Sheets = area ÷ 32 (4×8 sheet) with 10% waste. Estimates per square foot: 1.25 screws, 0.01 gallons of joint compound, and about 0.4 linear feet of tape for typical seams.
