Frequently Asked Questions
A board foot is a unit of measurement for lumber volume. One board foot equals 1 foot × 1 foot × 1 inch (or 144 cubic inches). It is commonly used in the lumber industry to measure and price wood.
To calculate board feet, use the formula: Board Feet = (Length in feet × Width in inches × Thickness in inches) / 12. For example, a board that is 8 feet long, 6 inches wide, and 1 inch thick equals (8 × 6 × 1) / 12 = 4 board feet.
The board foot formula is: Board Feet = (Length × Width × Thickness) / 12, where length is in feet, and width and thickness are in inches. This formula calculates the volume of lumber in board feet.
A 2×4×8 board (2 inches thick, 4 inches wide, 8 feet long) equals (8 × 4 × 2) / 12 = 5.33 board feet. Note that nominal dimensions (2×4) are slightly larger than actual dimensions due to planing.
To calculate board feet for multiple boards, first calculate the board feet for one board using the formula, then multiply by the quantity. For example, if one board is 4 board feet and you have 10 boards, the total is 4 × 10 = 40 board feet.
Board feet is a lumber-specific unit (1 bf = 144 cubic inches), while cubic feet is a general volume unit. One board foot equals approximately 0.0833 cubic feet. Board feet accounts for the standard lumber thickness of 1 inch.
To convert board feet to cubic feet, divide board feet by 12. For example, 24 board feet = 24 / 12 = 2 cubic feet. This conversion works because 1 board foot = 1/12 cubic feet.
Nominal dimensions are the rough-cut size before planing (e.g., 2×4), while actual dimensions are the finished size after planing (e.g., 1.5×3.5 inches). Board foot calculations typically use nominal dimensions for pricing, but actual dimensions for precise measurements.
Hardwood board feet are calculated the same way as softwood: (Length × Width × Thickness) / 12. Hardwood is often sold in board feet, and the calculation method is identical regardless of wood species.
In construction, board feet are calculated using nominal dimensions. For example, a 2×4×8 uses 2 inches (thickness) × 4 inches (width) × 8 feet (length) = (8 × 4 × 2) / 12 = 5.33 board feet per board.
