About Woodworking and Carpentry Maths Toolkit

Woodworking and Carpentry Maths Toolkit helps people estimate material quantities, compare lumber/timber costs, plan sheet goods, and understand common measurements before they start cutting.

The site is built for a global audience, so it focuses on measurement methods, formulas, and planning checks rather than country-specific rules or compliance claims.

Every calculator is free to use. The goal is to make the common maths behind board feet, sheet goods, deck boards, stairs, rafters, miters, cut lists, and wood weight easier to check before buying or cutting materials.

Start with the calculator list or read the guides to understand the maths behind the tools.
