QR Code Design Best Practices
A QR code must remain easy for cameras to scan. Good design should improve the appearance without reducing reliability.
Use enough contrast
Keep the QR pattern dark and the background light. Avoid pale colors and busy image backgrounds.
Leave a quiet zone
Keep an empty border around the code. Do not place text, logos, or design elements too close to its edges.
Choose the right size
Use a larger code for posters and billboards. Test it from the same distance where your audience will scan it.
