QR Code Generator – Best Practices & Tips
QR codes are a versatile tool for sharing URLs, contact information, and other data instantly with mobile users. When creating a QR code, following best practices ensures maximum scan reliability and accessibility. Proper sizing, error correction, URL cleanliness, and contrast all impact the effectiveness of your QR codes. Using high error correction levels allows logos or branding to be added without breaking the code. Always test QR codes on multiple devices and environments to ensure they work consistently.
QR Code Best Practices
Choose the Right Error Correction
QR codes support 4 levels of error correction: L (7%), M (15%), Q (25%), and H (30%). Use Q or H if you’re printing small or adding a logo to the center for branding.
Optimize for Mobile Devices
Ensure your QR code is large enough for quick scanning—at least 2 cm × 2 cm for print. Test on both iOS and Android devices before final use.
Use Short, Clean URLs
Shorter links create simpler QR codes, which scan faster. Use a URL shortener or tracking links (with UTM tags) for analytics.
Printing & Branding Tips
Keep high contrast (dark QR on light background). If adding logos, use Q or H error correction. Avoid inverted colors unless tested properly.
Higher Error Correction
Use Q or H if you plan to print small or place a logo near the center.
Contrast Matters
Keep foreground dark and background light for best scanning performance.
