Estimate shed framing lumber, siding, roofing, and foundation materials from dimensions.
A shed material calculator estimates lumber, siding, roofing, and foundation materials based on shed dimensions and roof pitch for accurate project planning.
| Size | Area | Use Case |
|---|---|---|
| 8×8 | 64 sq ft | Garden tools |
| 10×10 | 100 sq ft | Storage |
| 10×12 | 120 sq ft | Workshop |
| 12×16 | 192 sq ft | Large workshop |
| 12×20 | 240 sq ft | Garage/studio |
Formula
Studs = Perimeter ÷ 1.33 ft + Corners; Roof Area = Length × Rafter Length × 2Perimeter = 2 × (Length + Width) in feet
1.33 ft = 16 inches on center converted to feet
Rafter Length = (Width ÷ 2) × √(1 + (Pitch/12)²)
Worked Example
12×10 shed with 8 ft walls and 4/12 pitch
Did you know? According to the National Association of Home Builders, a quality storage shed can recoup 50-80% of its cost in added home value (source: NAHB).
