QR Code Best Practices

Creating effective QR codes requires attention to detail and following best practices. Here's what you need to know to create QR codes that work reliably.

Size Matters

The minimum size for a QR code depends on several factors:

• Scanning distance
• Data density
• Print quality
• Environmental conditions

Contrast is Key

• Use dark colors on light backgrounds
• Maintain at least 30% contrast ratio
• Avoid inverse colors in low-light conditions

Error Correction

QR codes support four levels of error correction:

1. Level L (7%)
2. Level M (15%)
3. Level Q (25%)
4. Level H (30%)

Testing is Essential

Always test your QR codes:

• On different devices
• In various lighting conditions
• At different distances
• On all intended surfaces

Common Mistakes to Avoid

1. Too much data
2. Poor placement
3. Insufficient quiet zone
4. Low contrast
5. Distorted proportions
