A simple, easy to use board footage calculator.

Below is a simple board footage calculator.

Board footage is the standard measurement for estimating lumber volume used in the forest-products industry. Technically speaking it is simply a unit of measurement, with one board foot equal to a board one foot wide, one foot long and one inch thick or 144 cubic inches.

To learn more about board footage and other common industry words, check out our glossary of common timber and lumber industry terms.

All factors should be inputted in inches. The thickness and width of your boards may be entered as either fractions of an inch such as 4/4 or 5/4, keeping with the industry standard, or as decimals such as 1.25 or 1.5. The calculator will round to the nearest quarter-inch.
