Good to know

How many pieces fit on a sheet?

Enter the sheet size and the piece size in the calculator on this page. It returns the number of pieces, the layout and the guillotine cuts. For example, a 12 by 18 inch sheet yields 30 business cards of 3.5 by 2 inches with no gap between pieces.

Is the calculator free?

Yes. It runs in the browser with no account, no ads and no limits. The native Mac app is free as well.

How does "Optimal" work?

It tests straight grids in both rotations plus mixed layouts, with rotated pieces filling the remainder, and keeps whichever yields the most. Same engine as the Mac app.

What are gap and margin for?

Gap adds cutting clearance between pieces. Margin reserves the unprintable edge of the sheet, because most digital presses cannot print to the very edge.

Does it work in centimeters?

Yes. The in and cm buttons switch units and convert whatever you already typed. The presets change too: inches shows trade sizes, centimeters shows ISO sizes such as A4, SRA3 and B2.

What is the difference between the online calculator and the Mac app?

The engine is the same, so the numbers match. The Mac app also saves your own sheets and cuts as presets, works with no connection and prints the cut plan for the operator.
