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.
| EC level | Recovers | Numerisch | Alphanumerisch | Byte | Kanji |
|---|---|---|---|---|---|
| L | ~7% | 4.965 | 3.009 | 2.068 | 1.273 |
| M | ~15% | 3.909 | 2.369 | 1.628 | 1.002 |
| Q | ~25% | 2.805 | 1.700 | 1.168 | 719 |
| H | ~30% | 2.157 | 1.307 | 898 | 553 |
Codewords and error-correction blocks
The symbol carries 2611 codewords in total, split between data and Reed-Solomon error correction (ISO/IEC 18004:2015, Table 9).
