8 Tips for Creating Effective QR Codes

8 Tips for Effective QR Codes

1. Always Test Before Printing

Scan your QR code with multiple devices. Different cameras may read them differently.

2. Choose High Error Correction

Level H allows a QR code to work even when up to 30% of its area is damaged.

3. Ensure Sufficient Contrast

A dark code on a light background is the classic approach. Avoid colored backgrounds that reduce contrast.

4. Don't Overload with Data

The more data, the more complex the code and the harder it is to scan. Use short links.

5. Add a Call to Action

Text like "Scan for a discount" or "Scan the menu" increases conversion by 30-50%.

6. Maintain Minimum Size

For print, a QR code should be at least 2×2 cm. For billboards — at least 30×30 cm.

7. Leave a Quiet Zone

A white border around the code (at least 4 modules) is required for proper scanning.

8. Use SVG for Print

Vector format scales without quality loss.
