Board Foot Calculator — Lumber Volume

How the board foot calculator works

A board foot is a lumber volume measure: 1 in thick × 12 in wide × 12 in long. Use nominal thickness and actual width.

Formula: BF = (T in × W in × L in) ÷ 144 per board

(2 × 4 × 96) ÷ 144 = 5.33 board feet per 8 ft 2×4.

Hardwood lumber is sold by the board foot. Prices range from $3/BF for common domestics to $30+/BF for exotics.
