Explainers
Board Foot (BF) measures lumber volume. Formula: (Thickness × Width × Length) ÷ 12 (T/W in inches, L in feet). Example: 2″ × 6″ × 10′ = 10 BF. Metric inputs are auto-converted.
Use Waste % to cover defects, saw kerf, and trimming. We add that on top of quantity.
Species density estimates weight. Real boards vary; weight is an estimate.

Board Foot Formula & Example
To make sense of the calculator, it’s helpful to know the formula behind it. Because the seed of everything should be known and strong.
Imperial Formula
(Thickness in inches × width in inches ×length in feet) ÷ 12
Metric Conversion
1 BF = 144 cubic inches ≈ 0.00236 cubic meters
Worked Example:
Board dimensions: 2″ thick × 6″ wide × 10 ft long
Calculation = (2 × 6 × 10) ÷ 12 = 10 BF
Result: one 2×6 board that’s 10 feet long = 10 board feet
Having information about it step by step will bless you with confidence in your calculations, saving you from time wastage in manual calculations. That’s why our board foot calculator is the right fit, as it offers bulk calculations instantly, giving you size, volume, weight, and cost in seconds.
FAQ’s
For manual calculations board feet formula is given as:
Thickness (inch) × width (inch) × length (feet) / 12 = Answer
For calculating price per board feet use this formula:
Total cost of lumber ÷ total number of board feet
Add the price per board foot in the calculator, which will, in turn, multiply it by the total BF cost to give you desirable results.
Conclusion
The board foot calculator used to be difficult, but now with our calculator, it has become super easy to use. You can estimate lumber size and volume instantly. Our calculator will automatically avoid errors that cause money wastage. The results will include accurate weight and cost breakdowns. And at the end, you can generate professional quotes. Try it now and calculate board feet, weight and cost in seconds without ever needing manual math again.
Extended FQAS
A board foot is a unit to measure the volume of wood. It is equal to a board that is :
- 1 inch thick
- 12 inches wide
- 12 inches long
It depends on the board’s length. Use the formula:
BF = Thickness (inch) × width (inch) × length (feet) / 12 = Answer
For a 2×4 that’s 8 feet long:
(2 × 4 × 8) ÷ 12 = 5.33
So, one 2×4 × 8 ft board = 5.33 BF.
If you had ten of them, it would be 53.3 BF.
First, add the total board feet of all boards together. Then, multiply that number by the price per board foot. For example, 50 board feet at $4 per BF would cost $200.
No, they are different. One board foot equals 144 cubic inches, while a cubic foot equals 1,728 cubic inches. In fact, one cubic foot equals 12 board feet.
A board foot measures volume, including thickness, width, and length. A linear foot only measures length. That’s why two boards of equal length can have very different board feet.
