Where 100 KB matters
A 102,400-byte file that sits exactly on the default request-body limit of Express. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Express body parsers | 100 KB (102,400 bytes) by default | A request body of exactly this size passes; anything larger returns 413 Payload Too Large. |
| Gmail message clipping | About 102 KB of HTML | Longer messages are truncated behind a "view entire message" link. |
| Amazon DynamoDB items | 400 KB per item | 100 KB fits; the 500 KB sample does not. |

Testing notes for WAV
- Not every WAV file has a 44-byte header; extra chunks may appear before the audio data, so parsers must walk the chunk list.
- Three MIME types are in common use: audio/wav, audio/x-wav and audio/vnd.wave. Allow-lists should accept all of them.
