What Is a Board Foot Calc?
A Board Foot Calculator is a digital or manual tool that calculates the volume of lumber in board feet (BF), the standard measurement for wood in the U.S. and Canada.
Why Board Feet?
Unlike linear feet (which only measure length) or square feet (which measure area), board feet account for thickness, width, and length, making it the most accurate way to price and purchase lumber.
How Does a Board Foot Calc Work?
The calculator uses a simple formula:
Formula:Board Feet (BF)=Length (ft)×Width (in)×Thickness (in)12×QuantityBoard Feet (BF)=12Length (ft)×Width (in)×Thickness (in)×Quantity
Example Calculation
| Measurement | Value |
|---|---|
| Length | 8 ft |
| Width | 6 in |
| Thickness | 1.5 in |
| Quantity | 2 |
Calculation:BF=8×6×1.512×2=12 board feetBF=128×6×1.5×2=12 board feet
This means you need 12 board feet of lumber for this project.
Where Is a Board Foot Calculator Used-

How to Use a Board Foot Calculator
- Enter Length (ft) – Measure the wood piece’s length in feet.
- Enter Width (in) – Measure the width in inches.
- Enter Thickness (in) – Measure thickness in inches.
- Input Quantity – Number of identical pieces.
- Click Calculate – Get instant board feet measurement.
1.What’s the difference between board feet and linear feet?
Board feet measure volume (L × W × T).
Linear feet only measure length.
2.How many board feet are in a 2x4x8?
BF=128×4×2=5.33 BF
3.Why divide by 12 in the formula?
Because 1 board foot = 12″ × 12″ × 1″ (144 cubic inches).
4.Is this calculator free to use?
Yes, most online board foot calculators are free with no signup required.
