How to use
- Enter thickness (inches), width (inches), length (feet) and the number of pieces.
- The board feet result updates live — no button to press.
- Check the cubic feet and cubic metres equivalents shown below the board feet.
- Adjust the pieces count to price or compare a full batch of timber.
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.
