Frequently Asked Questions

What is a board foot?

A board foot is a unit of volume: 12 inches long x 12 inches wide x 1 inch thick (144 cubic inches). It is the standard measurement for buying hardwood and rough-sawn lumber. Dimensional lumber (like 2x4s from a home center) is typically sold by the linear foot or per piece, not by board feet.
