QR Code Version 36 (161×161)
QR version 36 is 161×161 modules: up to 5,836 digits, 3,537 alphanumeric, 2,431 bytes or 1,496 kanji at level L; 1,051 bytes at H.
Version 36 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.
