How it's calculated

Board feet = thickness (in) × width (in) × length (ft) ÷ 12, times the number of boards. One board foot is 12 × 12 × 1 inch. Hardwood is measured at its rough thickness in quarters: 4/4 = 1 inch, 8/4 = 2 inches.

Example

Ten 1 × 6 boards, 8 ft long: 1 × 6 × 8 ÷ 12 × 10 = 40 board feet.
