QR test sheet
The same symbol at 15, 20, 25, 30, and 40 millimetres for a 100% scale print.
What it does: Prints the same symbol at 15–40 mm so you can test which size scans on paper.
What it does not: Fit-to-page printing makes millimetre captions wrong. A visual pass is not a scan guarantee.
Limits: Print at 100% scale. Use the size sheet download for a single PNG of all sizes.
