Lumber volume

Board Foot Calculator

Calculate board feet for actual lumber dimensions and quantity, with an optional cost using your entered price.

Enter actual lumber dimensions

Enter measurements and select Calculate.

Board-foot formula

Board feet = thickness in inches × width in inches × length in feet ÷ 12. Quantity multiplies the per-piece result. Optional cost uses only your entered price per board foot.

Actual dimensions

Enter measured or specified dimensions. The calculator does not translate nominal lumber names, optimize cutting, determine structural capacity, or retrieve supplier pricing.

Worked example

A 2-inch by 6-inch board that is 8 feet long contains 8 board feet. Ten pieces contain 80 board feet.

Estimate boundaries

Results use only your entered measurements and assumptions. No supplier, product, price, contractor, building-code, or geolocation API is contacted.
