Cut List Calculator

Use this calculator to reduce waste and avoid discovering a missing board after the saw is already set up.

Cut List Examples

Four 24 inch pieces from an 8 ft board

Four 24 inch cuts fit on a 96 inch board only if kerf and trimming are handled carefully. In practice, kerf makes this too tight unless pieces can be slightly short.

Shelf project with repeated cuts

For repeated shelf parts, group identical lengths first. This helps reduce setup time and makes it easier to spot whether longer stock saves waste.

Board and batten rails

For wall rails, use the longest boards you can transport safely. Fewer seams usually means a cleaner painted finish.

Good For

  • Dimensional lumber
  • Trim boards
  • Board and batten battens and rails
  • Shelving pieces
  • Repeated project parts

Before You Cut

  • Confirm final dimensions
  • Mark every piece
  • Plan for saw kerf
  • Cut longest pieces first
  • Keep one spare board when possible

Common Questions

What is a cut list?

A cut list is a board-by-board plan that lists each finished piece length, quantity, material, and which stock board it should come from.

What is saw kerf?

Kerf is the material removed by the saw blade. A typical circular saw or miter saw blade removes about 1/8 inch per cut, so accurate cut lists must account for it.

Should I buy extra lumber?

Yes. Even with an optimized cut list, buy at least 10 percent extra for knots, twisted boards, measuring mistakes, and setup cuts.
