Enter your values below. The calculator runs in your browser and shows an estimate immediately.
How the estimate is calculated
Board feet = T (in) × W (in) × L (ft) × quantity ÷ 12
Example: One 2 × 8 board that is 10 feet long contains 13.33 board feet. Four matching boards contain about 53.33 board feet.
When this calculator is useful
A board-foot tally is useful when comparing lumber lists, estimating stock for a cabinet or furniture build, or checking whether a quote covers the amount of wood you planned to buy. It gives volume, not the number of finished parts; include kerf, defects and offcuts in your own material plan.
How to use this calculator
Measure the rough lumber dimensions you are using for the estimate. Enter the number of identical boards, then select Calculate. The result is a volume estimate; it does not include a supplier’s minimum purchase, milling loss, defects, or a waste allowance.
What to keep in mind
Lumber yards may price surfaced or rough stock differently and may round board footage by piece or by order. Confirm the dimensions, grade, moisture condition, and pricing method with the Canadian supplier before ordering.
Frequently asked questions
What is a board foot?
A board foot is a lumber volume unit equal to a board 1 inch thick, 12 inches wide and 12 inches long.
How do I calculate board feet?
Multiply thickness in inches by width in inches by length in feet, then multiply by the board count and divide by 12.
Does the calculator include waste?
No. Add a separate allowance for knots, cuts, defects and project offcuts based on your plan.
Can I use this for lumber prices in Canada?
Yes, it estimates volume. Enter the price per board foot separately to estimate material cost; local suppliers may round their billing quantity.
