What size should a printed QR code be?
There is no single size that works for every payload and distance. A short URL produces fewer modules than a long vCard or a URL full of tracking parameters. Measure the final print, not the image in a design editor.
Set it up
- Choose the shortest useful payload and download SVG, not a screenshot.
- Set a physical code size based on the viewing distance and reserve a white margin outside the pattern.
- Print at final size and scan with different phones in the light and at the distance people will actually use.
What to encode
Use a short HTTPS destination for a URL code. Wi-Fi credentials and vCards are embedded data and may need a larger print area; shortening text helps more than simply raising error correction.
Print size and contrast
As starting points, try 2.5–3 cm for arm's-length cards and 8–10 cm for about 1 m. These are testing targets, not scan guarantees. Keep the generator's quiet zone visible, use dark modules on a light matte surface, and enlarge dense patterns.
Where to place it
Put the code on a flat, accessible surface away from curved corners, staples and glare. Leave enough room for a phone to frame it without stepping into traffic.
Common mistakes
- Cropping the white border removes the quiet zone.
- High error correction increases density; it cannot rescue tiny low-contrast printing.
- Screen previews do not model reflective laminate, ink bleed or viewing distance.
When to use a dynamic code
Dynamic URL codes carry a short redirect and can be less dense than a static URL with a long query string; they also let you change the destination later. For short permanent links, a free static code is often simplest. Dynamic redirects depend on the service and must not be deleted if printed copies must work.

FAQ
Can I print a QR code at 1 cm?
Some short patterns may scan in ideal conditions, but that is unreliable for general print. Start larger and verify a real proof.
Should I use SVG or PNG for a printer?
SVG is vector and remains sharp when scaled. If your printer requires PNG, export at sufficient resolution for the final physical size.
