What counts as a character
- Hashtags, @mentions, spaces and emoji all count.
- Emoji count as one character as you see them.
Best length vs the maximum
- Keep the visible part short and specific: what the video is and why to watch.
- Longer captions can help people find the video in TikTok search; write them as plain sentences, not keyword lists.
