QR Code Best Practices
Size Guidelines
- Print materials: Minimum 2cm × 2cm (0.8" × 0.8")
- Billboards: At least 30cm × 30cm at viewing distance
- Business cards: 1.5cm minimum, but 2cm recommended
- Screens: 150px × 150px minimum for digital display
Design Tips
- High contrast — Dark code on light background works best
- Quiet zone — Leave white space around the QR code (at least 4 modules)
- Test before printing — Scan with multiple phones to verify
- Use URL shorteners for complex URLs — shorter data = simpler QR code
Common QR Code Mistakes
- Too small to scan — Always test at the intended viewing distance
- Low contrast colors — Light gray on white won’t scan reliably
- Broken URLs — Test the link before generating the QR code
- No call to action — Add “Scan me” text near the QR code
Frequently Asked Questions
Do QR codes expire?
No. A QR code is just encoded data — it works forever. However, if the URL it points to goes down, the QR code becomes useless.
Can I customize the design?
Our QR Code Generator creates standard black-and-white codes. For branded QR codes with logos and colors, you’ll need a dedicated design tool.
Are QR codes secure?
The code itself is safe, but be cautious scanning unknown QR codes — they could link to phishing sites. Always check the URL before entering sensitive information.
