Formule

## How to Calculate Drywall Sheets ### Formula **Sheets = Total Area / Sheet Area × (1 + Waste Factor)** A standard 4×8 sheet covers 32 sq ft. A 4×12 sheet covers 48 sq ft. Add 10% for waste in rectangular rooms, or 15% for rooms with many corners and cutouts. One 4.5-gallon bucket of joint compound covers approximately 1,500 sq ft.

Exemple Résolu

A room with 60 ft of wall perimeter, 8 ft ceilings, using 4×8 sheets with 10% waste.

  1. 01Wall area = 60 × 8 = 480 sq ft
  2. 02Ceiling area = 0 sq ft
  3. 03Total area = 480 sq ft
  4. 04Sheets (no waste) = 480 / 32 = 15 sheets
  5. 05With 10% waste = 15 × 1.10 = 16.5 → 17 sheets
