Best Practices for QR Codes
Color Contrast
Use high contrast between foreground and background. Dark on light or light on dark works best for reliable scanning.
Logo Size
Keep logos small (30-40% of QR code size) and centered. Too large logos can make the code unscannable.
Minimum Size
For print, ensure QR codes are at least 2x2 cm (0.8x0.8 inches). Larger sizes improve scanning reliability.
Test Before Use
Always test your QR code with multiple devices and QR scanner apps before printing or publishing.
