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.
- 01Wall area = 60 × 8 = 480 sq ft
- 02Ceiling area = 0 sq ft
- 03Total area = 480 sq ft
- 04Sheets (no waste) = 480 / 32 = 15 sheets
- 05With 10% waste = 15 × 1.10 = 16.5 → 17 sheets
Questions Fréquentes
How many sheets of drywall for a 12×12 room?
For a 12×12 room with 8 ft ceilings: walls = 48 ft perimeter × 8 ft = 384 sq ft. That is 384/32 = 12 sheets for walls. Add ceiling (144 sq ft) = 4.5 more sheets. Total with waste: about 19 sheets.
What thickness of drywall should I use?
1/2-inch is standard for walls and ceilings. 5/8-inch is required for fire-rated assemblies and is recommended for ceilings to reduce sag. 1/4-inch is used for curved walls.
How much joint tape and compound do I need?
For every 1,000 sq ft of drywall, plan for approximately 370 ft of joint tape, one 4.5-gallon bucket of compound, and 700 drywall screws.
