Timber Yard Standards
Board feet calculations are based on the nominal dimensions of the lumber. Common softwoods like Pine weigh approximately 2.5 lbs per board foot, while denser hardwoods like Oak can weigh over 4 lbs per board foot.

Frequently Asked Questions
What is a Board Foot (BD FT)?
A board foot is a specialized unit of measure for the volume of lumber in the United States and Canada. It is equal to the volume of a 12-inch by 12-inch by 1-inch board.
How is board feet calculated?
Formula: [(Thickness in inches × Width in inches × Length in feet) / 12] × Quantity. This gives you the total volumetric measure of the wood.
What is nominal vs actual size?
Lumber is often sold by nominal sizes (e.g., a 2x4). However, the actual size is usually smaller (1.5x3.5) after surfacing. Most board-foot calculations for purchase are based on nominal dimensions.
How much does one board foot of wood weigh?
Weight varies by wood species. One board foot of Pine weighs about 2.5 lbs (1.1 kg), while White Oak weighs about 3.9 lbs (1.8 kg).
