About This Project
Free professional woodworking calculators for craftsmen worldwide
Hello, Fellow Woodworker!
I'm Kevin, the developer behind this site. I built these calculators because I kept doing the same math over and over — board feet, lumber costs, joinery measurements, workshop planning. Instead of keeping a messy spreadsheet, I turned them into free tools anyone can use.
Why This Site Exists
Accurate measurements matter in woodworking. A wrong cut wastes material, time, and money. These calculators help you get the numbers right before you pick up a saw.
Every formula is based on industry standards from the National Hardwood Lumber Association (NHLA), OSHA workshop safety guidelines, and established engineering principles. Each calculator is tested against real-world projects to ensure accuracy.
What You'll Find Here
No registration, no fees — just useful tools
Board feet, lumber costs, and material needs
Dovetails, mortise and tenon, and other joints
Dust collection, lighting, and layout calculators

Accuracy
All calculators use standard woodworking formulas and industry practices, tested across real projects. While I strive for precision, always double-check critical measurements for your specific projects and consult material suppliers for current pricing.
