Board Feet Calculator

Buying standard construction lumber is usually a straightforward process. You walk into a store, find a two-by-four, and pay a flat price per piece. However, if you are stepping up to build fine furniture, custom cabinets, or a beautiful new dining table, you will likely need hardwood. Buying hardwood introduces a completely different measurement system. Instead of buying by the piece, hardwood is sold by volume. This unit of measurement is called a board foot. Figuring out this volume can be confusing, but our Board Feet Calculator makes the process completely effortless. Let us look at what a board foot actually is, why suppliers use it, and how you can use our calculator to plan your next build perfectly.

What Exactly Is a Board Foot?

A board foot is the standard unit of measurement for hardwood lumber across North America. Unlike standard pine boards measured by simple length, a board foot measures the total volume of the wood.

One board foot is equal to a piece of wood that is one inch thick, twelve inches wide, and one foot long. In total, this equals 144 cubic inches of wood.

Why do hardwood suppliers use this system? Hardwood trees vary wildly in shape and size. When a mill cuts an oak or walnut tree, they try to maximize the usable wood rather than cutting everything into uniform sizes. Because pieces come in random widths and lengths, selling the wood by total volume ensures you only pay for the exact amount of wood you are getting.

How Our Board Feet Calculator Works

Doing volume math in your head while standing at a lumber yard is tough. We designed this calculator to do the heavy lifting for you. You can quickly figure out exactly how much wood you need and what it will cost.

Here is how you use the tool:

  1. Enter the thickness: Input the thickness of your board in inches.
  2. Add the width: Enter the width of the board in inches.
  3. Input the length: Drop in the total length of the board in feet.
  4. Select your quantity: Tell the calculator how many boards of this exact size you plan to buy.
  5. Include the price: Enter the supplier's price per board foot to get a reliable cost estimate.

Once you enter your dimensions, the calculator instantly reveals the total board feet and the estimated cost for your materials.

The Benefits of Calculating Board Feet Before You Buy

Walking into a hardwood dealer without knowing your required board footage can lead to expensive mistakes. Hardwoods like cherry, maple, and walnut are premium materials. Overestimating your needs will quickly drain your project budget.

By using the calculator at home, you get a clear and accurate shopping list. You will know exactly how much volume you need to complete your table or cabinet. This tool simplifies the ordering process, allowing you to compare prices between different suppliers easily. You can adjust your design plans on the fly if the total cost comes in higher than you expected.
