What this board foot calculator calculates
Ten boards that are 1.5 × 7.25 in actual and 8 ft long contain 72.50 board feet before waste.
Formula
Actual thickness × actual width × length in feet × quantity ÷ 12 = board feet.
Worked example
1.5 × 7.25 × 8 × 10 ÷ 12 = 72.50 board ft. Ten percent waste raises the order quantity to 79.75 board ft.
