Fill out all of the fields in the boxes, then click the "Calculate" button. Board Foot calculation will appear below in the "Results" panel, while the Total Board Feet will continue adding your total until you reset the calculator.
Board Foot Calculator
Here is a board foot calculator for figuring your lumber requirements. Just enter your desired thickness, width, length, and quantity and it will compute board feet and total board feet.
1. Hardwood lumber is typically sold by the board foot, a unit of volume equivalent to a board that is one inch thick, one foot wide and one foot long, or 144 cubic inches. Lumber thickness is expressed in quarters of an inch, beginning with 1 inch, so that 1 inch lumber is designated as 4/4, 1-1/2 inch lumber is 6/4, 2 inch lumber is 8/4, and so on. These units refer to nominal or roughsawn dimensions, not surfaced dimensions.
2. This program rounds lumber thickness up to the next 1/4" and lumber less than 4/4 is rounded up to 4/4. Thus, a specified thickness of 3/4" will be treated as 4/4" material.
3. You can enter fractional wood dimensions as decimals (12.75), or as conventional fractions (12 3/4). If you use fractions, just make sure you leave a space between any leading whole number and the fraction.
If you discover a tally shortage on H.I. Brand stamped lumber greater than 1%,
we will credit you the shortage AND a $100 bill.
We encourage you to verify lumber tally as a key component in purchasing your hardwood lumber. The NHLA allows a 4% value variation as acceptable. We don’t think a 4% variation is acceptable.
Our goal is to ship 100% of the lumber, 100% on grade. GUARANTEED.
Footage needs to be verified by a representative of Hardwood Industries. Applies to H.I. Brand stamped lumber with a computerized tally tag of 100 BF or more.
