TikTok hashtag counter
TikTok lets you add up to 5 hashtags per post. For posts made through TikTok’s official posting API (which scheduling tools use), the caption, hashtags included, can be up to 2,200 characters. Paste your caption below to count both, and to catch repeated hashtags and hashtags that won’t work. It runs in your browser, so nothing is sent or saved.

| Limit | Number | Source |
|---|---|---|
| Hashtags per post | 5 | Social Media Today (August 17, 2025) |
| Caption length, hashtags included (posts made through TikTok’s official posting API) | 2,200 characters (UTF-16) | TikTok for Developers, Direct Post reference (read November 11, 2026) |
In August 2025 creators started seeing an in-app message when they tried to add a sixth hashtag, and Social Media Today reported that TikTok was capping posts at five. TikTok has not published a formal announcement or a Help Center page with the number, so the app is the final word: if it lets you add five and blocks the sixth, five is your limit. The same goes for caption length: 2,200 is the figure TikTok documents for its posting API, and TikTok doesn’t publish a separate number for captions typed in the app.
How the counter counts
- Hashtags: a # followed by letters (any language), numbers or _. Each one is counted as written, repeats included, because a repeat still sits in your caption.
- Characters: every character, spaces, line breaks and hashtags included, counted in UTF-16 the way TikTok’s developer documentation describes. Most emoji count as 2.
- Problems it flags: more than 5 hashtags, the same hashtag twice (any capitalisation), a space after the #, hashtags stuck together, a # touching the word before it, and punctuation inside a tag.
- Soft note: over 2,200 characters (the posting-API limit, so a scheduling tool may cut the caption).
Hashtags that don’t work, with examples
# mealprep: the space after # means there is no hashtag. Write#mealprep.#mealprep#lunch: two tags glued together. Put a space between them.#don’tskipor#meal-prep: a hashtag stops at punctuation, so these become#donand#meal.#MealPrep #mealprep: the same tag twice takes two of your five slots.
How many hashtags should you use on TikTok?
Use 3 to 5 that describe the video accurately. With five slots, a tag that doesn’t describe the video takes the place of one that could. Our TikTok hashtag strategy guide covers how to pick them, whether their order matters and a two-week test you can run on your own channel.
How InayaFlow helps with this
This counter checks the format. Choosing the right tags is the harder part. The free TikTok channel analysis reads your recent public videos and shows your typical views, your engagement rate, your strengths, areas to improve and three recommendations, in about 30 seconds with no account and no password. Pro adds Content Ideas, Write My Script, Hashtags, Best Posting Times and Video Analysis, built on the same channel data. You still film and post everything yourself.
Frequently asked questions
How many hashtags can you use on TikTok?
Five. Since August 2025 the TikTok app has stopped creators from adding more than 5 hashtags to a post, as reported by Social Media Today. TikTok has not published a formal announcement, so if the app shows you a different number, the app is the rule.
How long can a TikTok caption be?
For posts made through TikTok’s official posting API, the caption can be up to 2,200 characters, hashtags included (TikTok for Developers, Content Posting API). Scheduling tools use that API. TikTok doesn’t publish a number for captions typed in the app, so if the app shows a different limit, the app is the rule. The counter counts in UTF-16, as the API page describes, so most emoji count as 2.
Do hashtags count toward the TikTok character limit?
Yes. Hashtags are part of the caption text, so every hashtag, including the # sign, uses caption characters.
Why is my hashtag not working on TikTok?
Common reasons: a space after the # sign, two hashtags stuck together with no space, or punctuation inside the tag (an apostrophe or a dash ends the hashtag early). The counter flags all three.
Does the counter save my caption?
No. It runs in your browser, nothing is sent or saved, and you don’t need an account.
