What is a Board Foot?

A board foot is a volume measurement used for lumber, equal to a piece of wood 12 inches long × 12 inches wide × 1 inch thick (144 cubic inches). Board feet is the standard unit for pricing lumber in North America.

How to Calculate Board Feet

The formula for board feet is: Board Feet = (Length in feet × Width in inches × Thickness in inches) ÷ 12

For example, a 2×4×8 board (actual dimensions: 2 inches thick × 4 inches wide × 8 feet long) = (8 × 4 × 2) ÷ 12 = 5.33 board feet.

Common Lumber Sizes

Nominal Size	Actual Size	Board Feet per Linear Foot
1 × 4	0.75" × 3.5"	0.22 BF/ft
1 × 6	0.75" × 5.5"	0.34 BF/ft
2 × 4	1.5" × 3.5"	0.44 BF/ft
2 × 6	1.5" × 5.5"	0.69 BF/ft
2 × 8	1.5" × 7.25"	0.91 BF/ft
4 × 4	3.5" × 3.5"	1.02 BF/ft

Practical Uses

Pricing: Lumber is typically sold by the board foot, making this calculation essential for cost estimates.
Project Planning: Calculate exactly how much lumber you need for construction or woodworking projects.
Material Ordering: Ensure accurate orders when purchasing from lumber yards or suppliers.
Inventory: Track lumber inventory in workshops and warehouses using standardized measurements.
