QR Code Best Practices
- Size matters: Minimum 2x2 cm for print, larger for distance scanning
- Contrast is key: Dark code on light background works best
- Test before printing: Always scan your QR code with multiple devices
- Add a call-to-action: Tell people what they'll get when they scan
- Don't over-complicate: More data = denser code = harder to scan
- Use SVG for print: Vector format ensures crisp edges at any size up to billboards
- Quiet zone: Leave white space around the QR code (at least 4 modules wide)
Frequently Asked Questions
Do QR codes expire?
Static QR codes never expire - the data is encoded directly in the pattern. However, if the URL they point to becomes invalid, they won't work. Dynamic QR codes depend on the redirect service staying active.
What's the maximum data a QR code can hold?
A QR code can hold up to 4,296 alphanumeric characters or 7,089 numeric characters. However, more data means a denser code that's harder to scan, so keep it under 300 characters for best results.
What size should I use for printing?
For business cards, use 300-500px. For posters and banners, use 1000-2500px. For maximum quality in print, download the SVG format which scales without losing quality.
Can I customize QR code colors?
Yes, but maintain high contrast. The code should be darker than the background. Avoid light colors like yellow or pastels for the code itself. Our tool generates standard black-on-white codes for maximum compatibility.
