What it calculates
Parts are sorted by area, then placed into available rectangles across as many sheets as needed. Every placement is rectangular and can be reached by straight, edge-to-edge cuts.

Turn a parts list into a practical sheet layout. Set the panel size and saw kerf, add the pieces you need, and see a guillotine-style cutting plan with estimated material yield.
Use one unit throughout— inches or millimeters both work. Dimensions are treated as finished part sizes.

The calculator reserves your kerf between neighboring pieces. Yield is finished part area divided by the full area of every sheet used, so sawdust and unused space both reduce the number.
Confirm actual sheet size, grain direction, edge trim, and blade kerf in your shop. A greedy layout is quick and useful, but it does not guarantee the mathematical minimum number of sheets.
