Planning a drywall project? Our Drywall Calculator is your essential tool for estimating materials like drywall sheets, screws, joint compound (mud), and tape. Avoid overspending or multiple trips to the store by calculating precisely what you need for walls and ceilings.
Formula:
The Drywall Calculator determines the total surface area to be covered, then estimates materials based on standard coverage rates and common sheet sizes.
- Total Area = (2 × (Room Length + Room Width) × Wall Height) + (Room Length × Room Width) - Deductions for Doors/Windows
- Drywall Sheets ≈ Total Area / Selected Sheet Size (with waste factor)
- Screws ≈ Total Area / Screw Coverage Rate (e.g., 0.9 lbs per 100 sq ft)
- Joint Compound (Mud) ≈ Total Area / Mud Coverage Rate (e.g., 4.5 gallons per 1000 sq ft)
- Tape ≈ Total Area / Tape Coverage Rate (e.g., 300 linear feet per 1000 sq ft)
