Hashtag Counter
Count the hashtags in your post, see them listed, and check against every platform’s limit — Instagram’s 30, X’s best practice of 1–2, TikTok, and LinkedIn.
About this tool
Every platform treats hashtags differently: Instagram allows 30 but engagement studies favor 3–5 focused tags; X allows any number but posts with 1–2 outperform; LinkedIn recommends 3; TikTok caption space (2,200 characters) is the real limit.
This tool extracts every #hashtag from your text, lists them so you can spot duplicates and typos, and shows counts against each platform’s limit.
A hashtag is counted from # through letters, numbers, and underscores — punctuation or a space ends it, matching platform behavior.
Everything runs locally in your browser — your text is never uploaded, stored, or shared.
Frequently asked questions
How many hashtags should I use on Instagram?
The cap is 30, but Instagram’s own guidance and most engagement studies suggest 3–5 highly relevant tags beat a wall of 30 generic ones.
What characters can a hashtag contain?
Letters, numbers, and underscores. A hashtag ends at the first space or punctuation mark — #year2026 works, but #year-2026 becomes just #year.
Do duplicate hashtags count twice?
This counter lists every occurrence and also shows the unique count. Platforms generally ignore exact duplicates, but repeated tags waste caption space.
