QR Code Best Practices

1. Size Matters

Minimum recommended size depends on scanning distance:

Business Cards - At least 2x2 cm (0.8x0.8 inches)
Posters/Flyers - At least 3x3 cm (1.2x1.2 inches)
Billboards - Size increases with distance: 1 cm per meter of scanning distance

2. Test Before Printing

Always test your QR code with multiple devices and QR scanner apps to ensure reliability across different platforms.

3. Add a Call-to-Action

Include text near your QR code explaining what users will get:

"Scan for 10% discount"
"Scan to visit our website"
"Scan for contact information"

4. Ensure Good Contrast

QR codes need high contrast between foreground and background. Dark patterns on light backgrounds work best. Avoid:

Light colors on light backgrounds
Low contrast combinations (e.g., gray on black)
Patterns or textures that interfere with scanability
