Introduction to QR Codes
QR (Quick Response) codes have become ubiquitous in modern marketing and business operations. These two-dimensional barcodes can store various types of data and are easily scanned by smartphones. Creating effective QR codes requires understanding best practices for design, content, placement, and usage. This guide covers everything you need to know to create QR codes that work well and achieve your business goals.
What are QR Codes?
QR codes are matrix barcodes that can store information in both horizontal and vertical directions, allowing them to hold much more data than traditional barcodes. They can encode text, URLs, contact information, Wi-Fi credentials, and more. QR codes are designed to be quickly readable by camera-equipped devices, making them ideal for bridging physical and digital experiences.
QR Code Best Practices
1. Choose the Right Content
Select content that provides value:
- URLs: Link to landing pages, product pages, or special offers
- Contact Information: vCard format for easy contact saving
- Wi-Fi Credentials: Allow easy network connection
- Text: Instructions, messages, or information
- Email/SMS: Pre-filled messages for easy communication
2. Optimize QR Code Size
Size matters for QR code readability:
- Minimum Size: At least 1cm x 1cm (0.4" x 0.4") for close scanning
- Recommended Size: 2-3cm (0.8-1.2") for comfortable scanning
- Distance Consideration: Larger codes needed for scanning from distance
- Print Quality: Ensure high-resolution printing for clarity
3. Ensure Proper Error Correction
QR codes include error correction to handle damage or partial obstruction:
- Level L (Low): ~7% error correction
- Level M (Medium): ~15% error correction (recommended)
- Level Q (Quartile): ~25% error correction
- Level H (High): ~30% error correction (for damaged codes)
Use higher error correction for codes that may be damaged or partially obscured.
4. Design with Branding in Mind
Customize QR codes while maintaining functionality:
- Color: Use brand colors, but ensure high contrast
- Logo: Add small logo in center (max 30% of code area)
- Shape: Customize corner squares while keeping them recognizable
- Background: Use light backgrounds with dark codes (or vice versa)
Always test customized QR codes to ensure they scan correctly.
5. Provide Context
QR codes should have clear context:
- Instructions: Tell users what to expect when scanning
- Value Proposition: Explain the benefit of scanning
- Call to Action: Use phrases like "Scan for discount" or "Scan to learn more"
- Visual Cues: Include smartphone icon or scanning instructions
Common QR Code Use Cases

- Print advertisements

Design Tips
Contrast is Critical
Ensure high contrast between QR code and background. Dark codes on light backgrounds work best. Test contrast ratios to ensure readability.
Quiet Zone
Maintain a "quiet zone" (white space) around the QR code equal to at least 4 modules. This ensures proper scanning.
Avoid Distortion
Don't stretch, skew, or distort QR codes. Maintain square aspect ratio and proper proportions.
Test Before Printing
Always test QR codes with multiple devices and scanning apps before mass production. Test in various lighting conditions.
Common Mistakes to Avoid
- Too Small: Codes that are too small to scan reliably
- Poor Contrast: Low contrast making codes unreadable
- No Context: QR codes without explanation or value proposition
- Broken Links: URLs that don't work or lead to error pages
- Mobile-Unfriendly: Links to desktop-only websites
- Over-Customization: Too much branding that breaks functionality
- Wrong Placement: Codes in hard-to-reach or poorly lit locations
