What is a woodworking calculator?

A woodworking calculator is a planning tool that helps estimate cut lists, plywood layouts, material quantities, board feet, waste percentage, and project cost before cutting or buying stock.

What is a cut list optimizer?

A cut list optimizer turns part dimensions, quantities, stock size, kerf, and layout rules into a cutting plan so woodworkers can reduce waste and review the project before cutting.

How do I reduce wood waste?

Reduce wood waste by measuring real stock, entering every part, accounting for saw kerf, reviewing grain direction, comparing layouts, and using a plywood or cut list calculator before buying material.

Which WoodCutTool page should I use first?

Start with the tools hub if you are choosing a workflow. Use the plywood cut calculator for sheet goods, the cut list calculator for boards, the wood waste calculator for scrap cost, and CutList for saved iPhone projects.

What is a kerf calculator?

A kerf calculator estimates the material removed by a saw blade by multiplying blade width by the number of cuts.

Why should I calculate kerf before making a cut list?

Kerf reduces the usable stock length, so including it before cutting helps prevent short final parts and more accurate waste estimates.
