If you’re buying lumber for a construction or woodworking project, you may wonder: how many board feet are in a 2×6×8?
The answer is:
A 2×6×8 board contains 8 board feet.
Board feet are commonly used to measure lumber volume in sawmills, woodworking shops, and construction projects.
In this guide, you’ll learn how to calculate board feet and see examples for different lumber sizes.
Quick Answer: 2×6×8 = 8 Board Feet
A board measuring:
- 2 inches thick
- 6 inches wide
- 8 feet long
contains:
8 board feet
What Is a Board Foot?
A board foot is a unit of volume used for lumber.
One board foot equals:
- 1 inch thick
- 12 inches wide
- 12 inches long
In other words, one board foot equals 144 cubic inches.
Board Foot Formula
To calculate board feet, use the formula:
For a 2×6×8 board:
- Thickness = 2 inches
- Width = 6 inches
- Length = 8 feet
Calculation:
(2 × 6 × 8) ÷ 12 = 8
Therefore:
2×6×8 = 8 board feet.
Step-by-Step Calculation
Step 1: Write down the dimensions
- Thickness: 2 inches
- Width: 6 inches
- Length: 8 feet
Step 2: Multiply the numbers
2 × 6 × 8 = 96
Step 3: Divide by 12
96 ÷ 12 = 8
Final result:
8 board feet
Board Foot Chart for Common Lumber Sizes
| Board Size | Board Feet |
|---|---|
| 2×4×8 | 5.33 |
| 2×6×8 | 8 |
| 2×8×8 | 10.67 |
| 2×10×8 | 13.33 |

Why Are Board Feet Important?
Board feet help estimate:
- Lumber costs.
- Project material needs.
- Wood volume.
- Sawmill production.
Many hardwood suppliers price wood by the board foot.
Actual vs. Nominal Lumber Size
Keep in mind that a 2×6 board is a nominal size.
The actual dimensions are usually:
- 1.5 inches thick
- 5.5 inches wide
However, board-foot calculations traditionally use the nominal size.
How Much Does a 2×6×8 Board Weigh?
The weight depends on the type of wood.
Typical weights:
| Wood Type | Approximate Weight |
| Pine | 14–16 pounds |
| Cedar | 12–14 pounds |
| Oak | 22–26 pounds |
Moisture content also affects weight.
