How It Works

A board foot is a unit of volume equal to a 1-foot by 1-foot by 1-inch piece of lumber (144 cubic inches). It is the standard unit for buying and selling hardwood lumber. The formula is: Board Feet = (Length x Width x Thickness) / 144, where all measurements are in inches. Common hardwood prices range from $3-5/BF for poplar to $8-15/BF for walnut and cherry, and $15-30+/BF for exotic species.
