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 | Numerisch | Alphanumerisch | Byte | Kanji |
|---|---|---|---|---|---|
| L | ~7% | 6.153 | 3.729 | 2.563 | 1.577 |
| M | ~15% | 4.775 | 2.894 | 1.989 | 1.224 |
| Q | ~25% | 3.417 | 2.071 | 1.423 | 876 |
| H | ~30% | 2.625 | 1.591 | 1.093 | 673 |
Codewords and error-correction blocks
The symbol carries 3196 codewords in total, split between data and Reed-Solomon error correction (ISO/IEC 18004:2015, Table 9).
