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

  1. Choose the shortest useful payload and download SVG, not a screenshot.
  2. Set a physical code size based on the viewing distance and reserve a white margin outside the pattern.
  3. 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.
