Board Ft Calculator
What is Board Feet?
Board feet is a unit of measurement used in the lumber industry to quantify the volume of wood. One board foot equals a 12-inch by 12-inch by 1-inch piece of wood. Accurately calculating board feet is essential for woodworkers, carpenters, builders, and anyone purchasing lumber to avoid overbuying or underbuying materials.
How to Use the Board Feet Calculator
Using the Board Feet Calculator is straightforward and requires only three inputs:
- Width (in inches): Enter the width of your board in inches.
- Thickness (in inches): Enter the thickness of your board.
- Length (in feet): Enter the length of the board in feet.
Once all fields are filled:
- Click the Calculate button to see the board feet value instantly.
- If you want to reset all inputs and start over, click the Reset button.
Step-by-Step Example
Let’s say you have a board that is 6 inches wide, 2 inches thick, and 10 feet long.
- Enter 6 in the Width field.
- Enter 2 in the Thickness field.
- Enter 10 in the Length field.
- Click Calculate.
Result: Board Feet=Width×Thickness×Length12=6×2×1012=10 board feet\text{Board Feet} = \frac{Width \times Thickness \times Length}{12} = \frac{6 \times 2 \times 10}{12} = 10 \text{ board feet}Board Feet=12Width×Thickness×Length=126×2×10=10 board feet
Now you know that your board contains 10 board feet of wood.

Advanced Examples
Example 1: Flooring Project
You need 30 boards, each 8 inches wide, 1.5 inches thick, and 12 feet long. Board Feet per Board=8×1.5×1212=12 board feet\text{Board Feet per Board} = \frac{8 \times 1.5 \times 12}{12} = 12 \text{ board feet}Board Feet per Board=128×1.5×12=12 board feet
Total Board Feet: 12×30=360 board feet12 \times 30 = 360 \text{ board feet}12×30=360 board feet
Example 2: Cabinet Making
A cabinet requires 5 boards, each 10 inches wide, 0.75 inches thick, and 6 feet long. Board Feet per Board=10×0.75×612=3.75 board feet\text{Board Feet per Board} = \frac{10 \times 0.75 \times 6}{12} = 3.75 \text{ board feet}Board Feet per Board=1210×0.75×6=3.75 board feet
Total Board Feet: 3.75×5=18.75 board feet3.75 \times 5 = 18.75 \text{ board feet}3.75×5=18.75 board feet
