Place a small, high-contrast logo near the center, preserve every finder pattern and use adequate error correction. The only reliable size limit comes from testing the finished code across devices and print conditions.
Quick answer: Place a small, high-contrast logo near the center, preserve every finder pattern and use adequate error correction. The only reliable size limit comes from testing the finished code across devices and print conditions.
Implementation workflow
- Shorten the encoded URL to reduce symbol density.
- Use Q or H correction and a logo with a simple silhouette.
- Add a clean background behind the logo instead of blending it into modules.
- Test screenshots, low-light cameras and the final printed material.
Professional quality checks
- Preserve the outer quiet zone.
- Do not recolor finder patterns with low contrast.
- Provide a readable URL fallback near important signage.
Before publishing, test the complete journey on mobile over both Wi-Fi and cellular data. Record the owner, objective, review date and fallback when the destination changes. For measured campaigns, give each meaningful touchpoint its own link so the data remains interpretable.
Measure the right outcome
Total clicks or scans are only an input signal. Reconcile them with post-click outcomes such as completed forms, bookings, reviews, downloads or purchases. Exclude obvious testing and automation, compare consistent periods and annotate destination changes.
Frequently asked questions
Where should the logo go?
Usually the center, away from the three large finder patterns.
Can I use a transparent logo?
Yes, but a controlled solid backing often scans more reliably than complex transparency.
