QR Code is encoded in 4 Types-1. Numeric - 3 characters are encoded to 10bit length.In theory, 7089 characters or less can be stored in a QRcode.2. Alphanumeric - 2 characters are encoded to 11bit length.In theory, 4296 characters or less can be stored in a QRcode.3. 8bit byte data- In from of 0 & 1In theory, 2953 characters or less can be stored in a QRcode.4. KANJI - A KANJI Character(this is multi byte character) isencoded to 13bit length.In theory, 1817 characters or less can be stored in a QRcode.
The Size of QR Code defined as version. Version is from 1 to 40. Version 1 is 21*21 matrix.And 4 modules increases whenever 1 version increases. So version 40 is 177*177 matrix.
