How it works

True Size mode: you tell the tool the real-world length of a line you draw on your photo (for example, a ruler visible in the shot, or a credit card's known 85.6 mm edge). From that, the tool computes pixels-per-millimetre and the image's true printed size, then tiles it across pages at exactly 1:1 scale. Poster mode instead scales the image to a chosen number of sheets wide, for wall art or signage where exact real-world size doesn't matter.

Every page includes a 10 mm calibration square - after printing at 100% scale (no “fit to page”), measure it with a ruler to confirm your printer didn't rescale the output.

Limitations

This tool accepts image files (JPG, PNG, WebP). PDF file input is not yet supported - export or screenshot a page from your PDF as an image first. Print accuracy also depends on your printer and paper handling; always check the calibration square before trusting a cut.

FAQ

What should I use as my calibration reference?
Anything with a precisely known length in the photo: a ruler, a credit card (85.6mm long), a sheet of A4/Letter paper, or a board you already measured.
My printer keeps scaling the page - what do I do?
In the print dialog, disable "fit to page" / "shrink to fit" and print at 100% or "actual size", then verify with the 10mm calibration square.
Can I use this for sewing patterns or woodworking plans?
Yes - True Size mode works for any image where you know one real dimension, including scanned or exported pattern pages.
