QR Codes with Logos: How Error Correction Makes It Possible
A QR code with a logo in the center is one of the most effective ways to combine branding with functionality. But how does it work? The logo covers part of the QR code, yet the code still scans. The answer is error correction.
This guide explains how branded QR codes work and how to design them for maximum scan reliability.
How Logo QR Codes Work
When you place a logo in the center of a QR code, you are physically removing QR modules. The scanner cannot read the modules covered by the logo.
The QR code can still scan because:
- Error correction recovers the missing data
- The center of a QR code contains the least critical data
- The finder patterns (corners) remain uncovered
Why the Center Is Safest
The QR code specification places data in a specific pattern across the code. The center region typically contains:
- Data modules (recoverable via error correction)
- Some error correction modules
The critical structures — finder patterns, timing patterns, and version information — are at the edges and corners.
Error Correction Requirements
| Logo Size (relative to QR) | Minimum Error Correction |
|---|---|
| 10% (small logo) | Level M |
| 15% (medium logo) | Level Q (recommended) |
| 20% (large logo) | Level Q or H |
| 25% (very large logo) | Level H |
| 30%+ (extreme) | Not recommended |
Rule of thumb: The logo should not exceed 20-25% of the total QR code area. If it does, scanning reliability drops significantly.
Logo QR Code Design Guidelines
Logo Size
The logo should be smaller than you think. A logo that occupies 15-20% of the QR code area is plenty visible while maintaining scan reliability.
Logo Shape
Circular logos work better than square logos. They cover fewer corner modules and blend more naturally with the QR code's rounded finder patterns.
Logo Background
Give your logo a white background or white border (at least 2-3 modules wide). This creates a clear boundary between the logo and surrounding QR modules.
Logo Position
Always place the logo in the center. Never place it over a finder pattern (corner).
Creating a Logo QR Code
Step 1: Choose Error Correction
Set error correction to Level Q or H. Level M may work for small logos, but Q is safer.
Step 2: Add a Quiet Zone Margin
Ensure the QR code has a clear quiet zone (margin) of at least 4 modules. The logo should not extend into the quiet zone.
Step 3: Generate Custom QR Code
Use a free QR code generator that supports center logo placement:
- Enter your URL or content
- Select Level Q or H error correction
- Upload your logo
- Adjust logo size (aim for 15-20% of QR area)
- Add a white border around the logo (if not already present)
- Test scan before finalizing
Common Logo QR Code Mistakes
| Mistake | Problem | Fix |
|---|---|---|
| Logo too large | Covers too many modules | Reduce to <20% |
| No error correction (Level L) | Logo covers more than 7% | Use Level Q or H |
| Logo over finder pattern | Scanner cannot find code | Keep logo in center |
| Dark logo on dark QR | Low contrast | Use white background |
| Complex logo details | Scanning confusion | Simplify or enlarge |
Case Study: Branded Campaign
A coffee chain placed QR codes with logos on 10,000 cups.
- Error correction level: Q
- Logo size: 18% of QR area
- Print size: 1.5 × 1.5 inches
- Scan success rate: 98.5% (vs 99.2% for logo-free codes)
Conclusion
QR codes with logos are an excellent branding opportunity. Use Level Q or H error correction, keep logos under 20% of the code area, and always test before printing at scale.
Create a branded QR code with your logo — generate QR codes with center logo placement and choose the right error correction level.
