How to Use This Hashtag Counter
Paste your caption (hashtags included) into the box and pick the platform to check against. The counter finds every hashtag in real time, shows the total, unique, and duplicate counts, and flags repeated tags — duplicates waste space without adding reach.
On Instagram mode it warns when you cross the hard 30-hashtag limit (posts and comments over it get rejected) and the 2,200-character caption limit. On X mode it checks against the 1–2 hashtag norm.
Use Copy hashtags to grab the deduplicated list and paste it into your caption or a saved-replies note.
Frequently Asked Questions
How many hashtags can I use on Instagram?
Up to 30 per post caption or comment — it's a hard limit, and Instagram won't publish text that exceeds it. Instagram's own guidance suggests 3–5 relevant hashtags work better than the maximum.
Should I use 30 hashtags or 3–5?
Test both for your account, but the trend favors fewer, highly-relevant tags. Hashtags today work more like topic labels that help the algorithm categorize your content than like search magnets — 30 generic tags can dilute that signal.
Do hashtags in comments count toward the limit?
Each comment has its own 30-hashtag limit, and hashtags in a comment on your own post still connect it to those topics. Some creators keep captions clean and put hashtags in the first comment — both approaches work.
Why should I avoid duplicate hashtags?
A repeated hashtag adds no extra reach — the post is indexed under that tag once. Duplicates just burn characters and slots you could spend on another relevant tag, which is why this tool highlights them.
How many hashtags should I use on X/Twitter?
One or two, and only when genuinely relevant. X has no hard cap, but hashtag-stuffed posts read as spam and every tag eats into your 280 characters.
