| Q2 |
How large is QR Code? |
| A2 |
The size of QR Code depends on a module size
and a symbol version. The module refers to the black and
white dots that make up the QR Code. The symbol version
determines the data capacity.
The area of a Version 1 QR Code is made up of 21 modules
per side. Each higher version number is made up of 4 additional
modules. The highest version number is Version 40.
For example, a Version 2 QR Code would be composed of a
25 by 25 module matrix. If the module size is 0.5 mm (19.7
mils) square, the size of QR Code will be 12.5 mm (0.5")
square. (QR Code requires a four module wide quiet zone
around the symbol.) |
