TikTok raised its caption limit to 4,000 characters, turning captions into a searchable, almost blog-like field - but the feed still truncates after the first line or two. The bio remains one of the smallest on any platform at 80 characters.
Verified July 2026. Platforms adjust limits over time.
| Field | Limit |
|---|---|
| Caption | 4,000 characters Feed shows only the first line or two |
