TikTok 2,200-Character Caption Truncation
Yes, TikTok captions allow 2,200 characters. But almost no one taps ...more. The first ~100 characters do the work.
TikTok captions accept 2,200 characters. That is the actual hard maximum. It's also a number that tricks new buyers into writing long-form ads that no one reads. Because the visible window is roughly 100 characters before TikTok appends "...more", the actual usable caption budget is ~95 characters of hook plus whatever you choose to hide behind the tap.
Tap-through rates on "...more" are even lower than Meta's See more taps. Aggregate published numbers from TikTok agency partners suggest 1–4% of viewers expand the caption — and that number drops to under 1% when the visible region doesn't earn the tap. In practical terms, anything past character 100 is invisible.
So why does TikTok offer 2,200 characters? Two reasons. First: parity with organic captions, where the limit was set generously to allow personal storytelling. Second: indexing — TikTok uses caption text for search and content matching, and a longer caption gives the algorithm more signal. So there's a defensible reason to write past 100 characters, but it's an SEO reason, not a conversion reason.

The 100-then-SEO pattern
Use the first 100 characters for human readers. Use characters 100–500 for keyword-rich descriptions that help discovery. Use characters 500–2,200 for hashtag stuffing if your strategy benefits from it. Keep the human-facing message tight.
FAQ
- Has TikTok always supported 2,200-character captions?
- Captions expanded from 150 to 300 in 2022, then to 2,200 in 2024. The visible-window cutoff has stayed at ~100 characters throughout.
- How many users tap '...more' to expand?
- Aggregate published reports indicate 1–4%. The number is lower than Meta's See more tap rate because TikTok scrolls faster.
- Should I stuff keywords into the long tail of the caption?
- Some advertisers do, with mixed results. TikTok's algorithm uses caption text but also relies heavily on the audio and visual signals.
- Are hashtags counted toward the 2,200-character cap?
- Yes. Hashtags eat the budget. Most creators move them to the end where they don't compete with hook copy.
