Each figure is from the network's own help or developer page, read on 9 November 2026. “Not published” means the network states no number, so we don't repeat one.
What the counter checks
- Count per network: against the network's own rule where it publishes one.
- Duplicates: the same tag twice, ignoring capital letters.
- Broken tags: a tag that stops at a dash, apostrophe or full stop, so #new-york is only #new.
- Length: each tag's length, flagged past Threads' 50 and Bluesky's 64.
- Arabic tags: kept as written, with words joined by an underscore. See Arabic hashtags to copy.
Hashtag counter FAQs
How long can a hashtag be?
Most networks don't publish a maximum length for a single hashtag: on Instagram, TikTok, X, Facebook and LinkedIn it is bounded only by the caption limit (2,200 characters on Instagram). Two networks do set one: Bluesky allows up to 64 characters per hashtag, and a Threads topic tag can be 1 to 50 characters. In practice, a tag people can read at a glance is the one they search for.
How many hashtags can you use on Instagram?
Five per post or Reel. Instagram announced the change in December 2025. Meta's developer page for apps that publish to Instagram still says 30, so you may see either number quoted; write to 5.
How many hashtags can a YouTube video have?
Up to three show by your title. If a video has more than 60 hashtags, YouTube ignores every hashtag on it.
How many hashtags can I use on Threads?
One topic tag per post, 1 to 50 characters, with no periods or ampersands.
Why did my hashtag stop at a dash or an apostrophe?
A hashtag ends at the first space or punctuation mark, so #new-york becomes #new. Join the words instead (#NewYork) or use an underscore (#new_york). The counter flags tags that break this way.
Do Arabic hashtags work?
Yes. Join the words with an underscore, as in #عيد_الاتحاد, because a space ends the tag. Arabic letters and Arabic-Indic digits are kept as they are.
Do X, TikTok, Facebook and LinkedIn limit hashtags?
None of them publishes a per-post cap. The counter shows how many PersonaXpand adds by default on each, labelled as our default, not as the platform's rule.
