Adding a logo to your QR code creates instant brand recognition—but do it wrong, and your code won't scan. Here's how to get it right every time.
Why Logos Sometimes Break QR Codes
QR codes work by encoding data in specific patterns of dark and light modules. When you add a logo, you're essentially "covering up" some of this data. If your logo is too large or poorly positioned, it can obscure critical information that the scanner needs.
The 30% Rule
With high error correction enabled, QR codes can have up to 30% of their area covered while remaining scannable. However, not all areas are created equal:
- Safe zone - The center of the QR code, away from position markers
- Danger zone - Near the three corner squares (position patterns)
- Critical zone - The timing patterns connecting the corners
Best Practices for Logo Placement
1. Keep Your Logo Centered
Always place your logo in the exact center of the QR code. This is the safest area because:
- It's farthest from the critical position markers
- Error correction is most effective here
- It looks visually balanced
2. Size Matters
Your logo should occupy no more than 20-25% of the total QR code area for maximum reliability. Here's a quick reference:
| QR Code Size | Max Logo Size |
|---|---|
| 200×200 px | ~50×50 px |
| 300×300 px | ~75×75 px |
| 400×400 px | ~100×100 px |
3. Add a White Background
Always put a white or light-colored background behind your logo. This creates contrast and helps the scanner distinguish between your logo and the QR code data.
4. Use Simple Logos
Complex logos with many fine details can be hard to see at small sizes and may interfere with scanning. Opt for simple, bold logo versions when possible.
Common Mistakes to Avoid
- ❌ Making the logo too large (over 30% coverage)
- ❌ Placing the logo over corner position markers
- ❌ Using a low-contrast logo that blends with the QR code
- ❌ Stretching or distorting the logo
- ❌ Using transparent backgrounds without sufficient contrast
Testing Your Logo QR Code
Always test your QR code before printing or distributing:
- Scan with your smartphone's native camera app
- Test with a dedicated QR scanner app
- Try scanning at different distances
- Test in different lighting conditions
- Have others test on different phone models
