Formula for Board Foot Calculation
To calculate board feet, use this formula:
Board Feet = (Length in inches x Width in inches x Thickness in inches) ÷ 144
If the dimensions are in feet, convert them to inches first (1 foot = 12 inches) before applying the formula.
Example Calculation
If you have a piece of wood that is:
- Length: 8 feet
- Width: 6 inches
- Thickness: 2 inches
- Convert the length to inches: 8 feet x 12 = 96 inches
- Plug the values into the formula:
Board Feet = (96 x 6 x 2) ÷ 144 = 1152 ÷ 144 = 8 board feet
How to calculate board feet?
To calculate board feet, follow these steps:
Step-by-Step Process:
- Measure the Dimensions
Gather the following measurements for your piece of wood:- Length (in feet or inches)
- Width (in feet or inches)
- Thickness (in feet or inches)
- Quantity (number of boards)
- Convert to Inches (if necessary)
If any dimensions are in feet, convert them to inches:- 1 foot = 12 inches
- Use the Board Feet Formula
Apply the formula:
Board Feet = (Length in inches x Width in inches x Thickness in inches x Quantity) ÷ 144
Example Calculation:
Let’s say you have 5 boards, each with the following dimensions:
- Length: 8 feet

Difference between a board foot and a linear foot
The terms board foot and linear foot are both used in lumber measurement, but they represent very different concepts. Here’s a clear comparison:
Board Foot
A board foot is a measurement of volume. It represents a piece of wood that is 1 foot long, 1 foot wide, and 1 inch thick.
- Unit of Measure: Volume
- Formula:
Board Feet = (Length in inches x Width in inches x Thickness in inches) ÷ 144 - Used For: Pricing and estimating the total amount of wood required for a project.
Example:
A board that is 8 feet long, 6 inches wide, and 2 inches thick contains:
Board Feet = (96 x 6 x 2) ÷ 144 = 8 board feet
Linear Foot
A linear foot is a measurement of length. It refers to a straight measurement of a board’s length, regardless of its width or thickness.
- Unit of Measure: Length
- Formula:
Linear Foot = Length in feet (no width or thickness considered) - Used For: Pricing trim, molding, or other wood pieces where only length matters.
Example:
A board that is 8 feet long is simply 8 linear feet, no matter the width or thickness.
Key Differences
| Aspect | Board Foot | Linear Foot |
|---|---|---|
| What It Measures | Volume | Length |
| Dimensions Used | Length, Width, and Thickness | Length Only |
| Unit | Cubic Inches or Board Feet | Feet |
| Application | Pricing lumber for large projects | Pricing based on length (e.g., trim or molding) |
When to Use Each
- Use board feet for larger, dimensional lumber where width and thickness affect the total material cost.
- Use linear feet for narrow wood products like trim, planks, or decking, where only length matters.
What is a board foot insulation?
A board foot of insulation is a unit of measurement used to quantify the amount of spray foam insulation or similar products. It refers to the volume of insulation material that covers one square foot of area at a thickness of one inch.
Breaking Down the Concept:
- Unit Definition:
- 1 board foot = 1 square foot of surface area × 1 inch thickness.
- Example:
- If you apply spray foam to an area of 100 square feet at a thickness of 2 inches, you need:
100 square feet × 2 inches = 200 board feet of insulation.
- If you apply spray foam to an area of 100 square feet at a thickness of 2 inches, you need:
Why Use Board Feet for Insulation?
The board foot is ideal for measuring spray foam insulation because:
- Spray foam is applied in layers of varying thickness.
- It provides a standardized way to calculate how much insulation material is needed for a specific area.
Applications of Board Foot Insulation:
- Home Insulation: Walls, roofs, attics, and basements.
- Commercial Buildings: Large spaces where energy efficiency is key.
- Soundproofing: Additional benefit of spray foam insulation.
Types of Spray Foam Insulation:
- Open-Cell Foam:
- Less dense, offers soundproofing and insulation.
- Typically requires more material (board feet) due to lower R-value.
- Closed-Cell Foam:
- Higher density, better insulation per inch.
- Requires fewer board feet for the same R-value.
How to Calculate Board Feet for Insulation:
Use this simple formula:
Board Feet = Surface Area (square feet) × Thickness (inches)
Example:
- Surface Area: 200 square feet
- Thickness: 3 inches
- Calculation: 200 × 3 = 600 board feet
Benefits of Measuring in Board Feet:
- Accurate Material Estimation: Ensures the right amount of insulation is purchased.
- Budget Planning: Helps estimate costs since spray foam insulation is typically priced per board foot.
- Energy Efficiency: Allows for precise calculations to achieve desired R-values.
By understanding board foot insulation, you can plan your insulation projects more effectively and make informed decisions on materials and costs.
Common Lumber Applications and Their Calculations
Lumber is used in various construction and woodworking projects, each with specific measurement needs. Here’s a look at common applications and how to calculate the required lumber in board feet for each scenario.

| 12 | 12 | 1 |
| 24 | 6 | 1 |
| 24 | 12 | 2 |
| 48 | 6 | 2 |
| 48 | 12 | 4 |
| 96 | 6 | 4 |
| 96 | 12 | 8 |
Explanation of Board Feet Calculation
- For 4/4 Lumber (1″ thick), the board feet formula is:
Board Feet = (Length in inches × Width in inches × Thickness in inches) / 144
Since 4/4 lumber is 1 inch thick, the thickness is always 1 inch in the calculation. - For 8/4 Lumber (2″ thick), the formula is the same:
Board Feet = (Length in inches × Width in inches × Thickness in inches) / 144
The thickness here is 2 inches, so the calculation will result in higher board feet compared to 4/4 lumber of the same length and width.
Board Feet Chart for 8/4 Lumber (2″ Thick)
| Length (in inches) | Width (in inches) | Board Feet (per board) |
|---|---|---|
| 12 | 6 | 1 |
| 12 | 12 | 2 |
| 24 | 6 | 2 |
| 24 | 12 | 4 |
| 48 | 6 | 4 |
| 48 | 12 | 8 |
| 96 | 6 | 8 |
| 96 | 12 | 16 |
Example of Calculation Using the Chart
For 4/4 Lumber (1″ Thick):
- If you have a board with a length of 12 inches, a width of 6 inches, and a thickness of 1 inch, the calculation would be:
Board Feet = (12 × 6 × 1) / 144 = 0.5 board feet
This matches the chart for 12″ length x 6″ width.
For 8/4 Lumber (2″ Thick):
- If you have a board with a length of 12 inches, a width of 6 inches, and a thickness of 2 inches, the calculation would be:
Board Feet = (12 × 6 × 2) / 144 = 1 board foot
This matches the chart for 12″ length x 6″ width in 8/4 lumber.
