board feet = thickness″ × width″ × length″ ÷ 144 · (length in feet: ÷ 12 instead)
Board feet per board — 4/4 (1″ thick) stock
| Width ↓ · Length → | 4′ | 6′ | 8′ | 10′ | 12′ | 14′ | 16′ |
|---|---|---|---|---|---|---|---|
| 2″ | 0.67 | 1.00 | 1.33 | 1.67 | 2.00 | 2.33 | 2.67 |
| 3″ | 1.00 | 1.50 | 2.00 | 2.50 | 3.00 | 3.50 | 4.00 |
| 4″ | 1.33 | 2.00 | 2.67 | 3.33 | 4.00 | 4.67 | 5.33 |
| 5″ | 1.67 | 2.50 | 3.33 | 4.17 | 5.00 | 5.83 | 6.67 |
| 6″ | 2.00 | 3.00 | 4.00 | 5.00 | 6.00 | 7.00 | 8.00 |
| 8″ | 2.67 | 4.00 | 5.33 | 6.67 | 8.00 | 9.33 | 10.67 |
| 10″ | 3.33 | 5.00 | 6.67 | 8.33 | 10.00 | 11.67 | 13.33 |
| 12″ | 4.00 | 6.00 | 8.00 | 10.00 | 12.00 | 14.00 | 16.00 |
Thicker stock: multiply
4/4 × 15/4 × 1-1/46/4 × 1-1/28/4 × 2
10/4 × 2-1/212/4 × 316/4 × 4
Example: for an 8/4 board 6″ wide and 10′ long, the table gives 5.00; doubled for 8/4, that's 10 BF.
Remember: board feet use the rough (nominal) thickness — 4/4 counts as a full inch even though it surfaces to about 13/16″. Buy 15–20% over your math for waste.
