QR Code Version 37 (165×165)
QR version 37 is 165×165 modules: up to 6,153 digits, 3,729 alphanumeric, 2,563 bytes or 1,577 kanji at level L; 1,093 bytes at H.
Version 37 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.
| EC level | Recovers | Numeric | Alphanumeric | Byte | Kanji |
|---|---|---|---|---|---|
