Jordanhill School D&T Dept/CC-BY-2.0

A running foot a term used in woodworking and is the same as a linear foot or standard foot. All three terms refer to a one-dimensional measure of length or distance. Running feet are sometimes abbreviated to RFT.

The term “running feet” is used specifically to describe the length of a piece of lumber. This is in contrast to the term “board foot.” Board feet take length, width and thickness into account. A single board foot is 1/12 cubic foot. The board foot is the most common unit used for hardwood lumber, but running feet may be used to describe the same piece of lumber when referring only to its length.
