Resize QR code - will scanner read small size QR code ?
Hi, when I resize the QR code image, will be users able to scan it ? Will be resized QR code readable with mobile phone ?
You can change the size of QR code. When resizing the QR code, it is important to keep it sharp enough and also keep the dimension ratio (reduce the same percentage of both width and height).
The reading of QR code depends on scanning devices. Some devices may be able to read only bigger QR codes.
Recommended minimum size of QR code is 2 x 2 centimeters (0.8 x 0.8 inches). But you can often see QR codes with smaller dimensions. Mobile phones can usually read QR codes well, because phone cameras have a good capabilities.
