| Rule | Why It Matters |
|---|---|
| Dark QR on a light background | Scanners need contrast to read the code |
| Minimum print size: 1 inch | Smaller codes may not scan reliably |
| Leave white space around the code | The margin helps scanners identify boundaries |
| Always test before printing | A code that doesn't scan is wasted ink and money |
Always add a call-to-action near your QR code:
| Mistake | Fix |
|---|---|
| Using static codes for marketing | Use dynamic so you can update & track |
| Linking to non-mobile-friendly pages | Always check your page on a phone first |
| Printing QR codes too small | Keep codes at least 1 inch (2.5 cm) |
| Forgetting a call-to-action | People need to know why they should scan |
| Never checking scan performance | Use dynamic codes + analytics |
Ask: What do I want to happen after the scan? — Open a website, collect an email, show a menu, take a payment?
Static → simple, permanent info. Dynamic → marketing, tracking, flexibility. If unsure, choose dynamic.
A webpage, Google Form, PDF, payment link, or booking page. Make sure it looks good on mobile.
