What is a board foot?

One board foot is defined as a piece of lumber measuring 12 inches long, 12 inches wide, and 1 inch thick — or 144 cubic inches. The board foot calculator formula is straightforward:

For example, a 2×6 that is 10 feet long yields 10 board feet. Our calculator applies this formula instantly as you type, showing per-board and total results in real time.

Why use a dedicated lumber board foot calculator?

A general calculator works in a pinch, but a purpose-built wood board foot calculator handles the details that matter: multiple board sizes in a single cut list, price per board foot calculator logic for cost estimation, waste factor for realistic material planning, and unit conversions between imperial and metric. Whether you need a board foot calculator for lumber on a job site or a board foot calculator for logs in the workshop, this tool adapts to your workflow.

Log board foot calculator vs lumber calculator

A log board foot calculator typically estimates the usable lumber volume inside a log before it is milled. While that requires log-specific scaling rules (Doyle, Scribner, International), our board foot calculator log tool focuses on dimensional lumber — boards that have already been cut to standard thicknesses and widths. This covers the vast majority of woodworking and construction needs. If you work with rough lumber, simply measure the actual dimensions after surfacing for the most accurate tree board foot calculator results.

Price per board foot — know your costs

Lumber pricing varies widely by species, grade, and region. A price per board foot calculator helps you compare options before you buy. Enter the price per board foot your supplier charges, and the calculator shows the cost per board and the total project cost instantly. Whether pricing walnut, cherry, oak, or construction-grade pine, the per board foot calculator gives you line-item visibility into every dollar. This makes it easy to create accurate quotes for clients or stick to a project budget.

Conversions: linear foot and square foot to board foot

Sometimes you have measurements in other units. A linear foot to board foot calculator requires knowing the thickness and width, since board footage is a volume measure, not a linear one. Similarly, a square foot to board foot calculator converts area into volume by factoring in thickness. Our built-in calculator handles both — enter any combination of dimensions and the sq ft to board foot calculator logic is handled automatically behind the scenes. The linear board foot calculator mode is built right into the same input fields.

Cut lists and project management

The board foot calculator app experience goes beyond one-off calculations. Build a multi-item cut list, adjust quantities, and see running total board feet and total cost. Toggle the waste factor slider (default 5%) to account for offcuts and mistakes — a must for any serious project. Your cut list is saved in your browser automatically, so coming back to a project is as simple as reloading the page. No accounts, no logins, no data sent to a server.

Built for professionals and hobbyists

Every detail of this board foot calculator is designed for speed and clarity. The isometric visualizer shows your lumber dimensions as a scaled 3D preview, so you can verify proportions at a glance. Quick Fill presets cover common lumber sizes (2×4, 2×6, 1×6, 4×4, and more), and the unit toggle switches between imperial and metric instantly. Whether you are a contractor estimating framing lumber or a hobbyist planning a bookshelf, this board foot calculator wood tool is built to save you time and reduce material waste.
