📚 What is a Board Foot?
A board foot is a unit of measurement for lumber volume. One board foot equals:
- 1 inch thick × 12 inches wide × 12 inches long
- 144 cubic inches of wood
- 1/12 of a cubic foot
📐 Formula
Board Feet = (Thickness × Width × Length) ÷ 144
Where thickness and width are in inches and length is in feet.
💡 Pro Tips
- Always buy slightly more than you need (add 10-15% for waste)
- Hardwood lumber is sold by board foot
- Softwood is typically sold by linear foot or board foot
- Thicker lumber costs more per board foot but may reduce waste
