What is a board foot?

One board foot equals 144 cubic inches of wood, or a piece 1 inch thick, 12 inches wide, and 12 inches long. The formula is: Board Feet = (Thickness × Width × Length) / 144.

Does nominal vs actual size matter?

Yes. A '2x4' actually measures 1.5 × 3.5 inches. Board feet are usually calculated using nominal dimensions for pricing, but actual dimensions for structural calculations.

How do I convert board feet to linear feet?

Divide total board feet by (nominal thickness × nominal width / 12). For example, 100 BF of 1x6 lumber equals 200 linear feet.
