Frequently Asked Questions
What is a board foot?
A board foot is a unit of lumber volume equal to 144 cubic inches — a piece 1 inch thick, 12 inches wide, and 12 inches long. Hardwood is sold by the board foot, while softwood is often sold by the linear foot. Rough lumber is measured before planing.
How much waste should I plan for?
Plan 10-15% waste for experienced woodworkers with clear lumber. Add 20-25% for beginners or lumber with defects. Projects requiring many small parts from large boards can waste 25-30%. Always buy extra rather than run short mid-project.

Yes, completely free with no signup required. Use it as many times as you need — there are no limits or hidden fees.
