TikTok Caption Character Limit

The short answer

TikTok allows up to 4,000 characters in the caption. The 4,000 figure applies to captions written in the TikTok app. Scheduling tools that post through TikTok's API are reported to cap captions at 2,200, so keep to 2,200 if you schedule.

What counts toward the limit

Letters, numbers, spaces, emojis, hashtags and mentions all count.

How much people actually see

Captions are cut after a short preview on the video, so the first sentence does the work.

Tips for fitting your caption

• Put the keyword in the first sentence, because TikTok search reads captions.
• Use a few relevant hashtags rather than a wall of them.
• Write for people who are skimming with the sound off, and say what the video is about.

How this compares with other limits

Platform	Field	Limit
Instagram	Caption	2,200
TikTok	Caption	4,000

Limits come from platform help pages and published guides, and platforms change them. Where it matters, confirm in the app. See every limit on the character limits hub.
