Design Best Practices
Your QR code needs to be scannable and visually appealing. Here's how:
Size Matters
- Minimum: 2cm x 2cm (0.8" x 0.8")
- Recommended: 3cm x 3cm for print materials
- Billboard/Large format: Scale proportionally to viewing distance
Contrast & Color
- Dark pattern on light background works best
- Maintain at least 40% contrast ratio
- Test colored codes on multiple devices
- Avoid very light colors that cameras struggle to detect
Placement Strategy
Physical Location
- Eye level is ideal (easier to scan)
- Well-lit areas only
- Flat surfaces when possible
- Away from reflective materials
Context is King
- Always include a call-to-action
- Explain what happens after scanning
- Make the value proposition clear
- Consider the user's situation
Technical Optimization
Error Correction
QR codes have built-in redundancy. Choose the right level:
- Low (7%): Maximum capacity, perfect conditions
- Medium (15%): Standard use case
- High (30%): Outdoor, curved surfaces, logo overlay
Landing Page Optimization
- Mobile-first design is essential
- Fast loading times (<2 seconds)
- Clear above-the-fold content
- Single, clear call-to-action
