What is a Board Foot?

A board foot (BF) is a unit of volume for timber in the United States and Canada. It represents a piece of wood that is 12 inches long, 12 inches wide, and 1 inch thick. Unlike square feet, which measure area, board feet measure volume.

How to Calculate Board Feet?

The standard board foot formula used by woodworkers and lumberyards is:

(Thickness (in) × Width (in) × Length (ft)) ÷ 12 = Board Feet

Note: If you measure length in inches, divide by 144 instead of 12.
