TikTok179 / 2,200 Unicode code pointsshows in full

TikTok can't publish without a video.

Counted in Unicode code points: one plain character is one, and a link costs its full length.

What TikTok hides, and where

A caption sits over the bottom of the playing video, one line deep, with the rest behind a tap. Nothing about that is a character count: it is the space left between the video and the action rail. Whatever is in the first line is what a scrolling viewer reads, and the tap to expand competes with a swipe to the next video.

Three posts TikTok only half shows

  1. The hook buried in sentence twoA setup line, then the payoff.Only the setup shows over the video. On TikTok the caption's first line does the job a headline does everywhere else.
  2. Publishing without a visibility choiceAn upload with no privacy level set.It lands private. TikTok requires the creator's explicit choice, and without one the video falls back to self-only - it looks published and nobody can see it.
  3. A photo carouselSix stills instead of a video.Not this flow. The Direct Post API we publish through takes one video; photo posts are a separate flow we do not build on.

Only on TikTok

  • One video per post through the Content Posting API - photo carousels are a separate flow we do not use.
  • The caption becomes the post's title field, not a separate description.
  • A visibility choice is mandatory; without one the upload defaults to private.
  • Video uploads are chunked: 5 MB minimum chunk, 64 MB maximum, up to 4 GB total.

Questions

Is this TikTok post preview free?
Yes. There is no login and no upload: it runs entirely in your browser, and nothing you type or attach leaves your device.
How long should a TikTok caption actually be?
The field takes 2,200 characters and the screen shows about one line over the playing video. Anything past that first line is behind a tap that competes with a swipe, so the working length is a sentence - the rest of the 2,200 is room for tags, not for writing.
Does the preview match what TikTok actually shows?
It is the same chrome our studio uses before a post publishes: TikTok's current header layout, action row and media grid, in either of TikTok's themes. Engagement numbers are decorative, as in every scheduler's preview.
Does TikTok cut the post off in the feed?
TikTok shows the whole post in the feed - nothing folds, so the 2,200-character limit is the only cut.
How long can a TikTok post be?
2,200 characters. Counted in Unicode code points: one plain character is one, and a link costs its full length.

Where these numbers come from: our sourced TikTok spec page, every figure carrying its citation and the date we last checked it.
