Calculate board feet and cost for any lumber dimensions.
Formula: Board Feet (BF) = (thickness × width × length) ÷ 12. All dimensions in inches and feet as marked. Total BF = BF per piece × quantity.
| Nominal | Actual (inches) |
|---|---|
| 1×2 | 3/4 × 1-1/2 |
| 1×4 | 3/4 × 3-1/2 |
| 2×4 | 1-1/2 × 3-1/2 |
| 2×6 | 1-1/2 × 5-1/2 |
| 2×8 | 1-1/2 × 7-1/4 |
| 2×10 | 1-1/2 × 9-1/4 |
| 2×12 | 1-1/2 × 11-1/4 |
| 4×4 | 3-1/2 × 3-1/2 |
Note: Board feet are calculated using nominal dimensions, not actual dimensions. This is the standard industry practice for pricing.
