Timber Cut List Optimiser

Plan cuts from standard timber lengths, reduce waste, include blade kerf, and keep useful offcuts with a practical online timber cut list optimiser.

Best for: Studs, rails, noggins, joists, battens and repeated cut lengths Helps with: Waste reduction, stock planning, kerf and reusable offcuts

What a Timber Cut List Optimiser Does

A timber cut list optimiser works out how to cut the pieces you need from the stock lengths you can actually buy. Instead of guessing how many 2.4 m, 3.6 m or 4.8 m lengths to order, it helps you build a cutting plan that uses the material more efficiently.

This is especially useful when a project includes a mix of short and long cuts, repeated quantities, or more than one timber section such as `3x2` and `4x2`.

Why It Helps Reduce Waste

Timber is expensive, and wasted lengths add up quickly across even a modest job. If the optimiser helps you avoid just a small amount of unnecessary over-ordering or waste, the cost of using it can easily pay for itself.

Who This Tool Is For

How to Use the Timber Optimiser

  1. Choose Linear Timber mode.
  2. Set the blade kerf in millimetres.
  3. Choose the stock lengths you can buy for each timber size.
  4. Enter each cut length and quantity required.
  5. Run the optimiser to see a purchase summary, cut plan, and reusable offcuts.

Blade Kerf and Reusable Offcuts

Two details make a timber cut list much more realistic:

If you want a cut list calculator that behaves more like a real workshop plan, both of these settings matter.
