Intro
Learn how to calculate board foot with ease! Discover 5 simple methods to determine the volume of lumber, including lineal feet, width, and thickness. Master the art of board foot calculation and improve your woodworking projects with accuracy. Get the formula and examples you need to calculate board foot like a pro.
Calculating board feet is a fundamental skill for anyone who works with lumber, whether you're a carpenter, woodworker, or DIY enthusiast. Board feet is a unit of measurement that represents the volume of a piece of lumber, taking into account its thickness, width, and length. In this article, we'll explore five easy ways to calculate board feet, making it easier for you to estimate the amount of lumber you need for your projects.

Understanding Board Feet
Before we dive into the calculation methods, it's essential to understand what board feet represents. A board foot is equal to a piece of lumber that is 12 inches long, 12 inches wide, and 1 inch thick. This unit of measurement helps you calculate the total volume of lumber required for a project, making it easier to estimate costs and avoid waste.
Why is Calculating Board Feet Important?
Calculating board feet is crucial for several reasons:
- Accurate estimation: By calculating board feet, you can accurately estimate the amount of lumber required for a project, reducing the risk of overbuying or underbuying.
- Cost savings: Calculating board feet helps you avoid waste and optimize your lumber usage, leading to cost savings.
- Efficient planning: Knowing the exact amount of lumber required for a project enables you to plan more efficiently, ensuring that you have the necessary materials on hand.
Method 1: Using a Board Foot Calculator
One of the easiest ways to calculate board feet is by using a board foot calculator. These calculators are available online and can be downloaded as apps or used as web-based tools. Simply enter the dimensions of your lumber, and the calculator will provide the total board feet.

Method 2: Using a Formula
If you prefer to calculate board feet manually, you can use the following formula:
Board Feet = (Thickness x Width x Length) / 12
Where:
- Thickness is the thickness of the lumber in inches
- Width is the width of the lumber in inches
- Length is the length of the lumber in inches
For example, if you have a piece of lumber that is 1 inch thick, 6 inches wide, and 8 feet long, the calculation would be:
Board Feet = (1 x 6 x 96) / 12 = 48 board feet
Method 3: Using a Board Foot Chart
Another way to calculate board feet is by using a board foot chart. These charts are available online or in woodworking books and provide a quick reference guide for calculating board feet based on the dimensions of your lumber.

Method 4: Measuring in Linear Feet
If you're working with lumber that is sold in linear feet, you can calculate board feet by multiplying the linear feet by the width and thickness of the lumber.
For example, if you have 10 linear feet of lumber that is 6 inches wide and 1 inch thick, the calculation would be:
Board Feet = 10 x 6 x 1 = 60 board feet
Method 5: Using a Spreadsheet
Finally, you can calculate board feet using a spreadsheet program like Microsoft Excel or Google Sheets. By creating a formula that takes into account the dimensions of your lumber, you can quickly calculate the total board feet required for your project.

Conclusion
Calculating board feet is a straightforward process that can be done using a variety of methods. By understanding the different calculation methods and using the right tools, you can accurately estimate the amount of lumber required for your projects, saving you time and money.
