dimensions you enter.
55 board feet total
How it works
Measure actual dimensions
Use a tape measure and record the actual thickness, width and length.
Count identical boards
Enter how many boards are the same size.
Calculate the board-foot volume
We convert the volume to board feet using the standard formula.
Rectangular boards only. No waste, kerf, defects or shrinkage allowance. Supplier billing may differ.
Questions, Answered.
What is one board foot?
One board foot is 144 cubic inches, equivalent to a 1 inch × 12 inch × 12 inch volume. It measures volume, not linear length.
Nominal or actual dimensions?
The formula uses exactly the values entered. Select the matching basis. A nominal label never triggers an automatic nominal-to-actual conversion.
Can I enter 1 1/2 instead of 1.5?
Yes. Positive decimals, fractions and mixed numbers are accepted for dimensions. Quantity must be a nonnegative whole number; zero quantity gives zero total volume.
