- 12 inches long
The standard formula is:
Board Feet = (Thickness × Width × Length) ÷ 12
Where:
- Thickness is measured in inches
- Width is measured in inches
- Length is measured in feet
This measurement helps buyers and sellers determine lumber quantities and pricing accurately.

- Total cubic feet
Example 1: Calculating a Single Board
Suppose you have a board with:
- Thickness: 2 inches
- Width: 8 inches
- Length: 12 feet
Formula:
Board Feet = (2 × 8 × 12) ÷ 12
Board Feet = 16
Result:
- Board Feet: 16
- Cubic Feet: 1.33
This information helps determine the amount of lumber available for a woodworking project.
Example 2: Calculating Multiple Boards
Assume you have:
- Thickness: 2 inches
- Width: 6 inches
- Length: 10 feet
- Quantity: 20 boards
Board Feet Per Board:
(2 × 6 × 10) ÷ 12 = 10
Total Board Feet:
10 × 20 = 200
Total Cubic Feet:
200 ÷ 12 = 16.67
Result:
- Per Board: 10 Board Feet
- Total: 200 Board Feet
- Cubic Feet: 16.67
This helps estimate total material volume before purchasing lumber.
