Exact 1:1 output
A scale ruler is printed on the assembly guide. Measure it with a tape measure — if it matches, your pattern is perfect.
True 1:1 scale
Print sewing patterns at actual size — no guesswork
Tile any pattern across A4 or Letter pages with exact scale. Overlap margins and assembly guide included.
Upload your sewing pattern, cosplay template, or quilting design. Set the exact dimensions and GridPrint splits it across pages at true scale. Print, cut, tape. The scale ruler confirms the size before you touch fabric.
Three steps to a full-scale pattern
01
Upload your pattern
Drop in your sewing pattern — downloaded designs or your own. PNG, JPG, SVG, whatever format you have.
02
Set exact dimensions
Enter the real-world size in cm or inches. GridPrint tiles the pattern across pages at true 1:1 scale.
03
Print, cut, assemble
Print the PDF at 100% (never "fit to page"). Cut along crop marks, overlap pages by the marked margin, and tape together.
Made for pattern printing
Overlap margins for taping
Configurable overlap (default 10mm) so pages align when taped. No gaps, no guessing where pages meet.
Numbered pages + assembly map
Every page is labeled. The assembly map shows the grid layout. Even 30-page patterns stay organized.
Works offline
Install as a PWA and use it at sewing meetups, retreats, or workshops. No internet after first load.
Frequently asked questions
Will the pattern be the right size?
Yes, if you print at 100% scale (not "fit to page"). Use the included scale ruler to verify before cutting fabric.
Can I print cosplay armor templates?
Yes. Upload the template, set the size to your body measurements, and print at true scale. Works for EVA foam, fabric, and Worbla patterns.
How much overlap should I use?
10mm works for most patterns. For large ones (20+ pages), 15mm gives more room for alignment.
My pattern is a PDF — does that work?
GridPrint takes image files (PNG, JPG, SVG, WebP). Export your PDF pattern as an image first, then upload it.
