QR-Code-Version 8 (49×49)
QR version 8 is 49×49 modules: up to 461 digits, 279 alphanumeric, 192 bytes or 118 kanji at level L; 84 bytes at H.
Version 8 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% | 461 | 279 | 192 | 118 |
| M | ~15% | 365 | 221 | 152 | 93 |
| Q | ~25% | 259 | 157 | 108 | 66 |
| H | ~30% | 202 | 122 | 84 | 52 |
Codewords and error-correction blocks
The symbol carries 242 codewords in total, split between data and Reed-Solomon error correction (ISO/IEC 18004:2015, Table 9).
| EC level | Data codewords | EC codewords | Blocks (count × total, data, EC codewords) |
|---|---|---|---|
| L | 194 | 48 | 2 × (121, 97, 24) |
| M | 154 | 88 | 2 × (60, 38, 22) + 2 × (61, 39, 22) |
