A QR code does not have to be a boring black-and-white square. With the right approach, you can customize your QR codes to match your brand while keeping them perfectly scannable. Here are seven practical design tips.
1. Maintain high contrast
The most important rule: dark modules on a light background. Your QR code scanner works by detecting the contrast between the dark and light areas. Black on white gives the highest contrast and the most reliable scans. If you use custom colors, make sure the foreground color is significantly darker than the background.
Avoid: light gray on white, yellow on white, pastel on pastel, or dark on dark combinations.
2. Do not invert colors
Never create a QR code with light modules on a dark background (like white on black). While some modern scanners can handle inverted codes, many older devices and apps cannot. Stick with the standard: dark foreground, light background.
3. Add a logo carefully
You can place a small logo in the center of your QR code because of built-in error correction. The logo covers some of the data modules, but the error correction algorithm can compensate — up to a point. Keep your logo to no more than 20% of the QR code area, and use the highest error correction level (H) when generating the code.
Qrafy supports center logos with automatic error correction level H.
4. Keep the quiet zone
The "quiet zone" is the white border around the QR code. It must be at least 4 modules wide on all sides. This border helps the scanner distinguish the QR code from its surroundings. Never crop it or place other design elements too close to the edge of the code.
5. Use brand colors wisely
You can replace the default black with your brand's primary color — as long as it is dark enough. A dark navy, deep green, or rich burgundy will scan fine. The background can be white, cream, or any very light color. Always test after changing colors.
6. Choose the right size
Size depends on scanning distance. For business cards, 2x2 cm minimum. For posters, 5x5 cm or larger. For billboards, 15+ cm. Read our complete size guide for detailed recommendations.
7. Always test before printing
This is non-negotiable. After customizing your QR code, scan it with at least two different phones (one Android, one iPhone) in different lighting conditions. Test the printed version, not just the screen version. What looks good on a monitor might not scan well on paper.
