QR Code Best Practices for Maximum Scans
1. Size Matters: Minimum size should be 2cm x 2cm for close-range scanning. For posters and billboards, use larger QR codes (10cm x 10cm or bigger).
2. High Contrast: Use dark patterns on light backgrounds. Black on white provides best scanning results. Avoid low contrast color combinations.
3. Test Before Printing: Always test your QR code with multiple devices before printing. Ensure it scans correctly from different angles and distances.
4. Add Context: Include call-to-action text like "Scan to Pay", "Scan for Menu", "Scan to Connect WiFi" near your QR code.
5. Error Correction: Our generator uses high error correction level (Level H) which allows QR codes to be readable even if 30% damaged.
6. Clear Placement: Place QR codes at eye level in well-lit areas. Avoid curved surfaces, reflective materials, and areas with poor lighting.
Difference Between Static and Dynamic QR Codes
Static QR Codes: The information is encoded directly in the QR code. Cannot be changed after generation. Perfect for permanent information like WiFi passwords, business cards, or fixed URLs. Our free generator creates static QR codes that work forever without any tracking or expiration.
Dynamic QR Codes: Contains a short URL that redirects to the actual content. Can be edited after creation. Usually requires paid subscription services with analytics and tracking features.
