Tips
- Board foot = thickness (in) × width (in) × length (ft) ÷ 12 — one line to remember.
- Timber markets often price per cubic foot (12 board feet = 1 cubic foot) — compare both.
- Enter rough-sawn sizes, not finished sizes, when buying from a sawmill.
Note
Board Foot = thickness (in) x width (in) x length (ft) / 12. 1 board foot = 144 cubic inch, and 12 board feet = 1 cubic foot. In timber markets the price is usually set per cubic foot.
