For creating a QR codes, the numeric characters, which are made up of 3 characters, are encoded into 10-bit length. The alphanumeric characters are encoded into 11-bit length, the 8-bit byte data, and Kanji characters can be encoded into 13-bit length. The size of the encoded data can vary from version 1 to version 40, where version 1 is 21 X 21 and 4 modules increase as the version number increases.
