How to Calculate Board Feet from Inches

When all dimensions are in inches, multiply thickness × width × length and divide by 144 (12 × 12) to get board feet. One board foot equals 144 cubic inches, or the volume of a board 1 inch thick, 12 inches wide, and 12 inches long. This is the standard unit for pricing hardwood lumber.
