About Board Foot Calculator

We built Board Foot Calculator to solve a simple problem: calculating lumber quantities shouldn't require a spreadsheet or guesswork.

Whether you're a professional contractor pricing a job, a hobbyist woodworker planning your next project, or a lumber yard employee helping customers, you need quick, accurate board foot calculations.

After years of watching woodworkers struggle with manual calculations and outdated tools, we decided to create something better. Our calculators are designed to be:

• Instant — Results update as you type, no submit buttons • Accurate — Industry-standard formulas, properly rounded • Free — No subscriptions, no hidden features • Private — No account required, calculations stay on your device

Our toolkit includes calculators for board feet, log scaling, unit conversions, and cost estimation. Each tool is built with real-world use cases in mind, from quick single-board calculations to multi-item tally sheets for large projects.

All calculations use industry-standard formulas:

• Board Feet: (Thickness × Width × Length) ÷ 144 • Log Scaling: Doyle, Scribner, and International 1/4" rules • Conversions: Precise mathematical conversions between board feet, square feet, and linear feet

Results are rounded to 2 decimal places for practical use.
