What Is a Board Foot?

A board foot is a standard unit used to measure the volume of lumber. One board foot represents 144 cubic inches of wood, which is equivalent to a board measuring 1 inch thick, 12 inches wide, and 12 inches long.

How to Calculate Board Feet

Board feet can be calculated by multiplying the thickness in inches by the width in inches and the length in feet, then dividing the result by 12.

Board Foot Formula
Board Feet = (Thickness × Width × Length) ÷ 12

Board Foot Calculation Example

For example, if a board is 2 inches thick, 8 inches wide, and 10 feet long:

(2 × 8 × 10) ÷ 12 = 13.33 board feet

Lumber measurements can be provided in different units depending on where you buy the material or how your project is measured. This calculator lets you enter thickness, width, and length in inches, feet, yards, centimeters, or meters. The calculator automatically converts the values before calculating the board feet.
