QR Code Best Practices
- Test Before Printing: Always scan your QR code with multiple devices and apps before printing
- Use Adequate Size: For print materials, aim for at least 2x2 cm (0.8x0.8 inches) minimum size
- Ensure Good Contrast: QR codes need high contrast - dark codes on light backgrounds work best
- Add Call-to-Action: Tell people what they'll get by scanning (e.g., 'Scan for menu', 'Scan to connect')
- Don't Over-Customize: Heavily stylized QR codes may not scan reliably - keep it simple
- Check URL Destinations: Make sure URLs work and lead to mobile-friendly pages
Frequently Asked Questions
What can I encode in a QR code?
QR codes can store URLs, plain text, email addresses, phone numbers, SMS messages, WiFi credentials, vCard contact info, geographic coordinates, cryptocurrency addresses, and more. The limit is around 4,296 alphanumeric characters for QR codes.
What size should my QR code be?
For digital use (websites, emails), 256px is sufficient. For business cards, use at least 300px. For posters and billboards, use 512px or higher. As a rule of thumb, QR codes should be at least 2x2 cm (0.8x0.8 inches) when printed.
Do QR codes expire?
No, QR codes themselves never expire. However, if the QR code links to a URL and that URL changes or goes offline, the QR code will no longer work. That's why it's important to use permanent URLs when possible.
Can I track who scans my QR code?
Basic QR codes cannot track scans. To track scans, you need to use a dynamic QR code service or link the QR code to a URL with analytics (like Google Analytics UTM parameters). Our tool creates static QR codes for privacy.
How do I share WiFi using a QR code?
Use this format: WIFI:T:WPA;S:YourNetworkName;P:YourPassword;; Replace 'T' with your security type (WPA, WEP, or leave blank for open networks), 'S' with your network name, and 'P' with your password. Guests can scan and connect instantly.
Are these QR codes free to use commercially?
Yes! All QR codes generated with our tool are completely free to use for any purpose - personal, commercial, or otherwise. There are no licensing restrictions or fees.
