Add your parts
Type your finished dimensions or paste a four-column table. Check quantities and choose whether rotation is allowed.
Review every sheet
Check the numbered parts, dimensions and any parts that could not fit. Part numbers identify pieces, not the order of cuts.
How is material usage calculated?
Material used is the area of placed parts divided by the area of the full sheets used. The remaining percentage includes kerf, edge trim and offcuts; it is not all reusable material.
Are these guaranteed minimum-sheet results?
No. The calculator tries several straight-cut packing strategies and selects a feasible layout. It does not guarantee the fewest possible sheets or check joinery, machine clearances or structural design.
Where is my project saved?
The current project stays in this browser’s local storage. There is no account or cloud sync. Clearing browser data removes the saved project. Nothing is sent to an AI or cutting service.
Can I use different materials or thicknesses?
Run each material and thickness as a separate project. This first version uses one stock size per calculation and does not mix sheets or use an offcut inventory.
