Free stained glass pattern tool
Scale your cartoon to real size and tile it for cutting glass.
Set the finished dimensions of your panel and the tool produces a full-size cutting pattern across standard sheets, with alignment marks and a calibration square so the assembled cartoon measures exactly what you set. It runs entirely in your browser — the file never leaves your device.
Full-size cartoon
Scale a small design up to the real panel size — tiled across as many sheets as needed.
Cut-line accurate
A calibration square on page one confirms the print came out at 100% before you cut glass.
Centimetres or inches
Work in the unit your pattern uses; this tool starts in centimetres.
Clean assembly
Overlap and alignment marks make the sheets line up when you trim and tape the cartoon.

Questions
Can I print a stained glass pattern larger than one page?
Yes — the cartoon tiles across as many A4 or Letter sheets as the finished size needs, with alignment marks so the pieces line up.
Will the pattern be the exact size I set?
Print at 100% / Actual Size and the assembled cartoon measures the dimensions you entered; the calibration square on page one confirms the scale before you cut.
Are my files uploaded?
