Placement Guidelines
Based on 10,000+ QR scans analyzed:
- Eye-level placement (4-5ft for adults) scans 40% faster

- Allow 2" clearance around the code
Key Takeaways
- 1.Test every QR code with multiple devices before distribution
- 2.Shorter URLs (under 50 chars) create cleaner, more scannable codes
- 3.Always have a fallback URL for print materials (e.g., "example.com/qr123")
