Frequently Asked Questions
What is a board foot?
A board foot is a unit of measurement for lumber volume. One board foot equals 144 cubic inches, or a piece of wood that is 1 foot long, 1 foot wide, and 1 inch thick.
How do you calculate board feet?
Board feet = (Length × Width × Thickness) ÷ 144, where all measurements are in inches. For example, a 2×4 that is 8 feet long equals 5.33 board feet.
Why use board feet instead of linear feet?
Board feet account for both the length and cross-sectional area of lumber, making it a more accurate way to measure and price wood. It ensures you're paying for the actual volume of wood you're purchasing.
