QR Code Version 33 (149×149)
QR version 33 is 149×149 modules: up to 4,965 digits, 3,009 alphanumeric, 2,068 bytes or 1,273 kanji at level L; 898 bytes at H.
Version 33 data capacity
Maximum characters in a single encoding mode, per error-correction level (ISO/IEC 18004:2015, Table 7). Mixed-mode data and ECI headers reduce these limits.
