Using QR Codes on Signage: Complete Guide
Physical signs with QR codes are one of the most effective ways to bridge offline and online marketing. Here's how to do it right.
Step 1: Choose the Right Location
Place QR codes where people naturally pause and have time to scan:
- At eye level (approximately 1.5-1.7 meters high)
- Near waiting areas (elevators, queues, reception desks)
- On product displays
- At point-of-sale locations
Step 2: Determine the Right Size
QR code size depends on scanning distance:
- Close range (30-50 cm): Minimum 2x2 cm
- Medium range (1-2 meters): 5x5 cm to 10x10 cm
- Far range (3+ meters): 15x15 cm or larger
Rule of thumb: QR code should be 1/10th of the scanning distance.
Step 3: Design Best Practices
- Use high contrast (black on white or white on dark background)
- Maintain quiet zone (white border around code, minimum 4 modules wide)
- Test readability before printing
- Add a call-to-action near the code
Step 4: Add Clear Instructions
Always include:
- "Scan with your phone camera"
- What users will get (e.g., "Get 20% off", "View menu", "Learn more")
- Alternative access method (URL) for users without QR readers
Step 5: Test Before Deployment
Test your QR code:
- On different devices (iPhone, Android)
- In various lighting conditions
- From different angles
- With different QR code reader apps
