In this guide, you will learn what board feet are, how the calculator works, how to use it effectively, practical examples, and helpful tips for accurate lumber calculations.
What Is a Board Foot?
A board foot is a standard unit of measurement used in the lumber industry to determine the volume of wood. It represents the volume of a board that measures:
- 1 foot long
- 12 inches wide
- 1 inch thick
This measurement allows lumber sellers and buyers to standardize pricing and volume calculations regardless of board dimensions.
For boards that differ in size, the board foot value is calculated using a simple formula that considers length, width, and thickness.
Instead of calculating this manually every time, the Linear Board Foot Calculator performs the calculation instantly and accurately.

How to Use the Linear Board Foot Calculator
Using the calculator is straightforward. Follow these steps to calculate board feet and lumber cost.
Step 1: Enter the Board Length
Input the length of the board in feet. For example, if your board is eight feet long, enter 8.
Step 2: Enter the Board Width
Input the width in inches. If the board is 6 inches wide, enter 6.
Step 3: Enter the Board Thickness
Provide the thickness in inches. Common thickness values include 1 inch or 2 inches depending on the lumber.
Step 4: Enter Price per Board Foot
Enter the cost of wood per board foot. This helps calculate the total value of the lumber.
Step 5: Click the Calculate Button
The calculator will instantly display:
- Total board feet
- Total lumber value
Step 6: Reset if Needed
Use the reset option to clear inputs and start a new calculation.
Board Foot Calculation Formula
The calculator uses the standard lumber formula:
Board Feet = (Length × Width × Thickness) ÷ 12
Where:
- Length is measured in feet
- Width is measured in inches
- Thickness is measured in inches
Dividing by 12 converts the dimensions into board feet.
Example of a Board Foot Calculation
Let’s look at a practical example.
Example Scenario
You have a board with the following dimensions:
- Length = 10 feet
- Width = 8 inches
- Thickness = 2 inches
- Price per board foot = $5
Step 1: Calculate Board Feet
Board Feet = (10 × 8 × 2) ÷ 12
Board Feet = 160 ÷ 12
Board Feet = 13.33
Step 2: Calculate Total Price
Total Price = 13.33 × 5
Total Price = $66.65
Using the calculator, these values appear instantly without needing manual calculations.

Common Lumber Sizes and Board Foot Estimates
Here are examples of typical lumber sizes and their approximate board feet.
| Board Size | Length | Board Feet |
|---|---|---|
| 1×6 | 8 ft | 4 |
| 2×4 | 8 ft | 5.33 |
| 2×6 | 10 ft | 10 |
| 2×8 | 12 ft | 16 |
However, exact values depend on actual dimensions, which is why using a calculator ensures accuracy.
Tips for Accurate Lumber Calculations
To get the best results when calculating board feet, follow these tips.
Measure Carefully
Always measure the board dimensions accurately before entering them.
Use Correct Units
Make sure the length is in feet and width/thickness are in inches.
Double-Check Lumber Thickness
Many lumber boards are sold with nominal sizes that differ slightly from actual dimensions.
Include Price per Board Foot
Entering the correct price allows accurate cost estimation.
Calculate Multiple Boards
If working with multiple boards, calculate each separately or sum their dimensions if identical.
