Board Foot Calculator

Board Foot Calculator

Our Board Foot Calculator is a simple tool that helps you quickly determine how much wood you need for your project. Whether you're a woodworker, contractor, or DIY enthusiast, this calculator helps estimate lumber volume in board feet—saving time, money, and material waste.

What Is a Board Foot?

A board foot is a unit of measurement for lumber volume. It represents a piece of wood that is:

• 1 inch thick
• 12 inches wide
• 12 inches long

This is equal to 144 cubic inches of wood. Board feet are commonly used in North America to price and size hardwood and softwood lumber.

Board Foot Formula

To calculate board feet manually, use the formula:

Board Feet = (Thickness [in] × Width [in] × Length [ft]) ÷ 12

For example:

A 2-inch thick, 6-inch wide, 10-foot long board =

(2 × 6 × 10) ÷ 12 = 10 board feet

How to Use the Board Foot Calculator

1. Enter the thickness of the wood in inches
2. Enter the width of the board in inches
3. Enter the length in feet
4. Click "Calculate" to get the number of board feet

The tool automatically applies the formula and provides an accurate result.
