This free TikTok character counter counts your caption the way TikTok does, so most emoji count as 2. A caption posted through TikTok's own API can be up to 2,200 characters, counted in UTF-16 units.
It shows Instagram and every other platform beside it, so you can see where else the same caption fits.
Here's TikTok's caption limit, why emoji count as 2, and how to write a TikTok caption.
What is a TikTok character counter?
A TikTok character counter is a tool that counts your caption the way TikTok's docs count, against the 2,200 characters TikTok allows for a caption posted through its API.
TikTok counts in UTF-16 units, the way computers store text, so most emoji count as 2. The app may let you type more than 2,200, so keeping under it keeps your caption safe everywhere. This one counts as you type, and shows the same caption on Instagram and the rest.
How to use the TikTok character counter
TikTok's caption limit
| Text | Limit | How it counts |
|---|---|---|
 TikTok caption | 2,200 | UTF-16 units, emoji 2 |
The limit comes from TikTok's own developer docs: "The maximum length is 2200 in UTF-16 runes." That's the limit for a caption posted through TikTok's API. The app itself may allow more.
What TikTok counts as a character
| What you type | How it counts |
|---|---|
| Letters, numbers, punctuation and spaces | 1 each |
| Most emoji | 2 each |
| An emoji with a skin tone, or a flag | 4 |
| A hashtag | The # and every letter after it |
The way it counts comes from TikTok's own developer docs.
Why emoji count as 2
Most emoji are stored as 2 UTF-16 units, and TikTok's docs count those units. A caption with 50 emoji uses 100 of its 2,200.
Writing a TikTok caption
- Front-load the hook: the start of the caption shows over the video.
- Put keywords in plain words: people search TikTok, so say what the video is about.
- Keep hashtags few and specific: they're part of the character count too.
Who the TikTok character counter is for
It's for anyone who posts on TikTok:
- Instagram character counter – creators who post the same video as a Reel
- YouTube character counter – people who post it as a Short too
- Video caption generator – anyone who adds subtitles to the video itself
- Post image generator – anyone who turns the idea into a photo post
An emoji-heavy caption can fit on Instagram and run long on TikTok, so check both before you post.
Post it everywhere
The counter above checks the same post on every platform at once, and each has its own page too: X, LinkedIn, Threads, Bluesky, Mastodon, Instagram, Pinterest and YouTube.
When it's ready, turn it into an image for the feeds that want one with my post image generator, and schedule it with the tools on my creator tools page.
