Size Recommendations
Minimum Sizes:
| Distance | Minimum QR Size | Recommended |
|----------|----------------|-------------|
| 4 inches | 0.4 x 0.4 in | 0.8 x 0.8 in |

Rule of Thumb: QR code size (inches) = Scanning distance (inches) ÷ 10
Placement Guidelines
Print Materials:
- Place at eye level or slightly below
- Ensure adequate lighting
- Provide clear scanning instructions
- Leave quiet zone (white space) around code
- Test scannability at intended distance
Digital Displays:
- Keep QR code stationary (no animations)
- Display for adequate duration (10+ seconds)
- Ensure high contrast with background
- Position for easy smartphone access
- Avoid glare and reflections
Color Contrast
Recommended Combinations:
- Dark blue on white

Testing Your QR Code
Pre-Launch Checklist:
□ Test on multiple devices (iPhone, Android)
□ Test with different QR scanner apps
□ Verify destination URL loads correctly
□ Check from intended scanning distance
□ Test in various lighting conditions
□ Verify with damaged/obscured sections
□ Test after printing (if applicable)
□ Confirm all vCard fields populate correctly
□ Verify WiFi credentials work
□ Check analytics tracking (if enabled)
Common QR Code Mistakes to Avoid
1. Poor Contrast
Using colors that don't provide enough contrast makes scanning difficult or impossible.
Solution: Always use dark colors on light backgrounds and test scannability.
2. Too Much Information
Encoding excessive data creates overly complex codes that are hard to scan.
Solution: Use URL shorteners or dynamic QR codes for long content.
3. Low Resolution
Pixelated or blurry QR codes won't scan reliably.
Solution: Export at minimum 300 DPI for print, use vector formats when possible.
4. Insufficient Size
Making QR codes too small for the scanning distance.
Solution: Follow the size guidelines based on scanning distance.
5. No Testing
Failing to test QR codes before mass production or distribution.
Solution: Always test on multiple devices and in real-world conditions.
6. Inverted Colors
Using light QR codes on dark backgrounds without proper testing.
Solution: Stick to traditional dark-on-light or thoroughly test inverted designs.
7. Missing Quiet Zone
Not leaving white space around the QR code.
Solution: Always include minimum 4-module quiet zone on all sides.
8. Unclear Call-to-Action
Not telling users what will happen when they scan.
Solution: Add clear text like "Scan for menu" or "Get your discount code."
