MAKER MOSAIC

About Maker Mosaic

Maker Mosaic is a free, browser-based tool for printing an image at its true real-world size across several sheets of paper. You set the scale by measuring a known length in your photo, choose a paper size and overlap, and export the tiled pages — then print them at 100% and assemble them into one large print.

Everything runs locally in your browser. Your images are never uploaded to a server, there is no account to create, and the tool is free to use.

Who it's for

Makers who need full-size printouts at home: cosplay armor and prop templates, sewing and quilting patterns, woodworking and CNC templates, posters and wall art, blueprints, and stencils.

How to print a photo to scale across multiple pages

1. Open Maker Mosaic and upload your image.
2. Select the Measure tool, draw a line over an object of known length, and enter its real size.
3. Pick your paper size (Letter, A4, or A3), DPI, and overlap margin.
4. Add alignment patterns if you want help lining up the seams.
5. Export as a ZIP of PNGs or a single multi-page PDF.
6. Print at 100% / actual size, trim the overlap, and tape the pages together.
