QR Code Design Best Practices
- Size matters: Print QR codes at least 2 cm × 2 cm (0.8 in × 0.8 in) for reliable scanning. Larger is always better.
- High contrast: Dark patterns on a light background scan best. Avoid light-on-light or busy backgrounds.
- Test before printing: Always test your QR code with multiple phones and scanning apps before mass production.
- Consider placement: Position QR codes where people naturally pause — eye level, well-lit, and accessible.
- Include a call to action: Tell people what they will get when they scan: “Scan to view our menu” works better than just a QR code alone.
- Error correction: QR codes with higher error correction levels can still be scanned even if partially damaged or obscured. Use at least H (30%) for printed materials.
Real-World QR Code Applications
Business Cards
Include a QR code on your business card that links to a vCard download. When someone scans it, your contact info (name, phone, email, company, website) is saved directly to their phone’s address book. No typing required.
Restaurant Menus
Post-pandemic, digital menus have become standard. A table tent card with a QR code lets customers view the menu on their phones. It is cheaper than printing menus, updates instantly, and reduces contact surfaces.
Event Registration
Include QR codes on flyers and posters that link directly to your event registration page. This removes friction between seeing the ad and signing up. Track scans to measure which placements drive the most registrations.
Common QR Code Mistakes
- Linking to non-mobile-optimized pages: Ensure the URL you link to works well on smartphones
- Using dynamic QR codes when static would work: Static QR codes never expire. Dynamic codes require ongoing service fees
- Poor contrast or tiny size: If the QR code is smaller than a coin or has low contrast, it will fail to scan in low light
- Not testing in real conditions: Test in the actual environment — outdoor light, distance, and angle all affect scan reliability
- Broken links: Double-check that the URL works and is typed correctly. A typo in the link means a dead end for scanners
