QR Code Best Practices
Creating effective QR codes goes beyond just generating the code. Follow these best practices to maximize scannability, engagement, and conversion rates.
QR Code Design Best Practices
DO
- Maintain high contrast - Use dark colors on light backgrounds for optimal scanning
- Include a quiet zone - Leave white space around the QR code (minimum 4x module width)
- Use error correction - Choose high error correction levels (H-30%) for branded QR codes
- Test before printing - Scan with multiple devices to ensure readability
- Keep logo small - Centrally placed and under 30% of the QR code area
DON'T
- Use low contrast colors - Avoid light colors on light backgrounds or dark on dark
- Make it too small - Never smaller than 2cm x 2cm in print materials
- Use inverted colors - Avoid white code on dark background
- Add too much information - Keep URLs short and simple
- Modify position detection patterns - Keep the corner squares intact
QR Code Placement Best Practices
Size & Visibility
- Minimum 2cm x 2cm for print materials
- Larger for billboards and distant viewing
- 10:1 rule - Make code 1/10th viewing distance
- Avoid curved or distorted surfaces
Accessibility
- Place at eye level when possible
- Include in multiple locations for events
- Consider physical accessibility (e.g., wheelchair height)
- Avoid shiny surfaces that cause glare
Environmental Factors
- Consider lighting conditions at the location
- Protect outdoor codes from weather damage
- Avoid placing where shadows fall on code
- Test scanning in actual environment
Optimizing QR Code Content

Mobile-Friendly
100% responsive design optimized for smartphone screens
Clear CTA
One primary call-to-action that's immediately visible without scrolling
QR Code Call-to-Action Best Practices
| Poor CTA | Effective CTA |
|---|---|
| "Scan this code" | "Scan to view our full menu with prices" |
| "QR Code" | "Scan to get 20% off your first order" |
| "More info here" | "Scan for exclusive video tutorial" |
| "Visit our website" | "Scan to book your appointment now" |
Elements of an Effective QR Code CTA:
- Action verb - Start with "Scan" to make it clear what to do
- Value proposition - Tell users what benefit they'll get
- Urgency (when appropriate) - "Limited time" or "Exclusive access"
- Visual indicator - Include a small phone/scanning icon
