Board feet calculator

Board footage for a lumber order.

How it is worked out

thickness × width × length in feet ÷ 12 = board feet per piece

What it assumes

Board feet use NOMINAL dimensions — a 2×10 is figured as 2 by 10, not its actual 1½ by 9¼.
Rough-sawn and hardwood are usually priced by the board foot; dimensional framing is usually priced by the piece.

Nothing on this page is a demo of the real thing — it runs the identical code. What a TradeForge account adds is everywhere the number then goes: saved against the job it belongs to, dropped straight onto a quote, and priced at a rate built from your own overhead instead of a guess.
