QR Code Best Practices

What you'll learn: Professional tips and strategies to maximize your QR code scan rates and campaign success.

Creating a QR code is easy. Creating one that people actually scan requires strategy.

This comprehensive guide covers everything from design principles to marketing strategies, helping you get maximum value from every QR code you create.

1 Design Principles

Contrast is King

High contrast between the QR code pattern and background is essential for scannability.

Best Practice
  • Dark colors on light backgrounds
  • Black on white (classic, always works)
  • Dark blue on cream
  • Navy on light gray
Avoid
  • Light gray on white
  • Yellow on light backgrounds
  • Inverted colors (white on black is risky)
  • Low-contrast pastels
Maintain the Quiet Zone

The "quiet zone" is the white border around your QR code. It's not optional—it's critical.

Rule: Maintain at least 4 modules (the smallest squares in the QR code) of white space on all sides.
Resolution Matters
  • Digital use: Minimum 300x300px
  • Print (small): 300 DPI at actual size
  • Print (large): Use SVG or high-resolution PNG
  • Billboard: Vector format (SVG) required

2 Placement and Size Guidelines

Minimum Size Requirements

Too small = unscannable. Follow these minimums:

Medium Minimum Size Recommended Size Scan Distance
Business Card 2cm (0.8in) 2.5cm (1in) 10-20cm
Flyer/Brochure 3cm (1.2in) 5cm (2in) 20-30cm
Poster (A4/Letter) 5cm (2in) 10cm (4in) 50cm-1m
Banner/Sign 15cm (6in) 30cm (12in) 2-3m
Billboard 1m (40in) 2m+ (80in+) 10m+
Strategic Placement
Visible

Place where people naturally look. Avoid corners or edges where QR codes get cropped or overlooked.

Accessible

Position at comfortable height (chest to eye level). Ensure people can physically get close enough to scan.

Well-Lit

Avoid shadows, glare, or poor lighting. Natural or bright artificial light is ideal.

Never place QR codes: On moving vehicles, curved surfaces (unless printed specially), behind glass with glare, or where scanning is unsafe (busy roads).

3 Testing Before Deployment

Always test before mass printing or publishing. Here's how:

Pre-Launch Testing Checklist:
Pro Tip: Have someone unfamiliar with your project test the complete scanning experience. They'll catch usability issues you might miss.

4 Content and URL Strategy

Keep URLs Short

Shorter URLs create simpler QR codes that are easier to scan.

  • Use URL shorteners for long links (bit.ly, TinyURL, etc.)
  • Create custom short domains for your brand
  • Avoid URLs with special characters when possible
Mobile-First Landing Pages

95%+ of QR code scans come from mobile devices. Your landing page must be:

Fast Loading
  • Load in under 3 seconds
  • Optimize images
  • Minimize scripts
Mobile-Responsive
  • Readable text without zooming
  • Touch-friendly buttons
  • No horizontal scrolling
Add Clear Call-to-Action

Tell people WHY they should scan your QR code:

✓ Good: "Scan to get 20% off"
✓ Good: "Scan for menu & specials"
✗ Bad: Just a QR code with no context
✗ Bad: "Scan for more information"

5 Tracking and Analytics Best Practices

Enable Tracking from Day One

You can't improve what you don't measure. Always track your QR codes.

  • Use our built-in analytics (Starter plan and above)
  • Add UTM parameters for Google Analytics tracking
  • Create unique codes for different campaigns to compare performance
  • Set up conversion goals on your landing pages
Key Metrics to Monitor
Metric What It Tells You Action Threshold
Scan Rate Are people seeing and scanning your code? Less than 1% of impressions = improve placement/CTA
Bounce Rate Are scanners staying on your page? Over 70% = fix landing page
Conversion Rate Are scanners taking your desired action? Under 5% = improve offer/UX
Time of Day When are people most engaged? Use for timing future campaigns

6 Security Considerations

Important: QR codes can be exploited. Follow these security practices.
Protect Your Users
  • Always use HTTPS: Secure all QR code destination URLs
  • Validate URLs: Ensure links go where intended
  • Monitor for tampering: Check physical QR codes aren't covered with malicious ones
  • Use branded short links: Users can verify legitimacy before clicking
Protect Your Brand
  • Register trademarks on custom QR code designs
  • Monitor for counterfeit QR codes
  • Use dynamic QR codes so you can change destinations if compromised
  • Add your logo to make codes harder to replicate
QR Code Phishing Prevention:

Educate your audience to:

  • Check the URL preview before opening (most phones show this)
  • Only scan codes from trusted sources
  • Be wary of QR codes that request personal information
  • Look for your official branding on QR materials

7 Marketing and Engagement Tips

Incentivize Scanning

Give people a compelling reason to scan:

  • Exclusive discounts: "Scan for 20% off your order"
  • Free content: "Get the free guide"
  • Contest entry: "Scan to enter our giveaway"
  • Convenience: "Skip the line—order ahead"
  • Experience: "View in AR" or "Watch the video"
A/B Testing

Test different approaches to optimize performance:

  • Different CTAs ("Scan here" vs. "Get 20% off")
  • QR code colors and designs
  • Placement locations
  • Landing page variations
Multi-Channel Integration

Use QR codes to bridge physical and digital:

  • Print to Digital: Flyers → Website
  • Product to Content: Packaging → How-to videos
  • Event to Social: Signage → Instagram page
  • Retail to eCommerce: In-store → Online checkout

! Common Mistakes to Avoid

Problem: Just showing a QR code without explaining why someone should scan it.
Solution: Always include a compelling call-to-action that explains the benefit.

Problem: QR code links to 404 error, wrong page, or expired content.
Solution: Test thoroughly before printing. Use dynamic QR codes so you can update URLs. Monitor links regularly.

Problem: Landing page isn't mobile-optimized, loads slowly, or requires desktop features.
Solution: Design mobile-first. Test on actual phones. Optimize for speed.

Problem: QR code is too small to scan, placed in a corner, obscured, or inaccessible.
Solution: Follow minimum size guidelines. Place prominently at comfortable scanning height.

Problem: Can't measure campaign success or optimize performance.
Solution: Always use trackable QR codes. Monitor analytics. Use insights to improve future campaigns.

Problem: QR code looks beautiful but won't scan due to poor contrast, complex patterns, or excessive logo size.
Solution: Prioritize function over form. Always test customized codes thoroughly before printing.
