Using QR Code Generator for printed materials

How to size and format a QR code so it actually scans / works when printed. Browser-based, free, no signup, runs entirely on your device.

Tool:QR Code Generator

Generating a QR code sounds like it should require an app — and historically it did. QR Code Generator runs the same thing in your browser tab, with one tap and no signup.

QR Code Generator for printed materials

Print is where QR code generation gets specific. The QR code needs to scan reliably from a few inches away, under uncontrolled lighting, possibly slightly crumpled or smudged.

Sizing rules

  • Minimum size for scanning at arm's length: 2 cm × 2 cm (about 0.8 inches).
  • For posters meant to be scanned from across a room: at least 10 cm × 10 cm, scaled up linearly with distance.
  • Always include the quiet zone — the empty border. Without it, scanners struggle.

Print-specific tips

Generate at the largest size you'll need, then scale down in the layout — never up. PNG with high error-correction is the safest format for press output. Test with a real phone before you commit to the print run.
