QR code best practices
The best QR code is not just technically valid. It is easy to scan, placed with intent, connected to a useful destination, and tested in the exact context where real people will use it.
1. Choose the right destination
- Use a short, reliable URL when possible.
- Match the destination to the context of the placement.
- Use dynamic redirects when the content may change later.
- Avoid sending users to slow, broken, or generic landing pages.
2. Keep the design scannable
- Use strong contrast with dark modules on a light background.
- Protect the quiet zone around the code.
- Be careful with logos, gradients, and decorative frames.
- Raise error correction when visual customization becomes heavier.
Branding is useful, but scan reliability matters more than visual flair.
3. Size it for the real environment
- Small print uses require a simple QR and sufficient physical size.
- Large posters and window graphics should be tested from real scan distance.
- Higher data density usually requires a larger final QR code.
4. Export the right file type
- Use SVG or EPS for print workflows.
- Use high-resolution PNG for digital placements and many standard print cases.
- Avoid screenshots and over-compressed JPG files.
5. Test before launch
- Test on iPhone and Android.
- Test from the real viewing distance.
- Test the final printed or embedded version, not only the generator preview.
- Confirm the destination still makes sense after scan.
