QR Code Fundamentals

What Makes a Good QR Code?

A good QR code should be:

• Scannable: Easy to detect and read
• Purposeful: Provides clear value to users
• Accessible: Works across different devices and apps
• Secure: Doesn't lead to malicious content

Types of QR Codes

Design Best Practices

1. Size and Resolution

2. Color and Contrast

Do:

• Use high contrast (dark code on light background)
• Maintain 3:1 contrast ratio minimum
• Test in grayscale to ensure readability

Don't:

• Use light colors on light backgrounds
• Make the code too colorful
• Invert colors (light code on dark background) unless necessary

3. Quiet Zone (Border)

Always include a quiet zone around your QR code:

• Minimum: 4 modules wide (the width of 4 squares in the code)
• Recommended: 6-8 modules for better scanning
