How this calculator works
Sheets and mud from wall/ceiling surface area with waste. Planning estimates only — verify measurements and local codes on site. Sheets = wall+ceiling sq ft ÷ 32 (4×8) × waste; mud ≈ sq ft × factor. Example: 12×14×8 room → ~13 sheets + ~4 gal mud (rough estimate).
Sheets = wall+ceiling sq ft ÷ 32 (4×8) × waste; mud ≈ sq ft × factor.
Example: 12×14×8 room → ~13 sheets + ~4 gal mud (rough estimate).
