How to Calculate Board Feet with a Board Foot Calculator

If you work with wood, knowing how to calculate board feet is important. A board foot calculator makes

This is much easier, helping you get accurate measurements and cost estimates. In this article, you’ll learn

How to use a simple, mobile-friendly calculator made for 2025.

What is a Board Foot?

A board foot is a unit of volume used in the lumber industry, representing a piece of wood

measuring 1 foot long, 1 foot wide, and 1 inch thick (or its equivalent). The formula for calculating

board feet is :

Board Feet = (Length × Width × Thickness × Number of Pieces) ÷ 12

All dimensions must be in feet, and the result provides the volume in board feet. For example,

A piece of lumber 8 feet long, 6 inches wide, and 2 inches thick (converted to feet: 8 × 0.5 × 0.167) yields

approximately 5.33 board feet for one piece.

Why Use a Board Foot Calculator?

Manually calculating board feet can be time-consuming, especially when dealing with multiple pieces or

mixed units (feet, inches, meters). A board foot calculator automates this process, offering :

• Accuracy : Eliminates errors in unit conversions and calculations.
• Versatility : Supports inputs in feet, inches, or meters.
• Cost Estimation : Calculates total cost based on price per board foot.
• Efficiency : Saves calculations for future reference and exports data as CSV.
• Visualization : Provides a 3D-like preview of lumber dimensions.
