31 hashtags on Instagram
Instagram enforces a real 30-hashtag cap, so a caption with 31 hashtags gets flagged as one over the limit.
Hashtag counter and limit checker
Paste a caption and see its hashtag count checked against every live platform's real hashtag limit at once — Instagram's 30, YouTube's 15 and Threads' 1, with the rest showing no enforced cap rather than an invented one. Counting uses the same rule the SkedCast composer and API gate on, not a simple split on spaces.
0 hashtags found. Counting happens in your browser — nothing is uploaded.

How to use the hashtag counter
- Paste your caption. Put the caption, hashtags included, in the box — counting happens in your browser as you type.
- Read the count per platform. Every live platform gets its own row, showing its real hashtag limit or that it enforces none at all.
- Check the over-limit warning. A platform row turns red when your hashtag count exceeds that platform's actual enforced limit.
- Trim hashtags for the tightest platform. Threads enforces just one hashtag, so a caption built for it needs the smallest tag set of any platform.
- Schedule with the same counting rule. SkedCast's own composer counts hashtags the identical way, so what you see here matches what it will enforce.
Worked examples
Two hashtags on Threads
Threads enforces just a single hashtag per post, so a caption with two hashtags is flagged as one over.
Hashtag counter FAQ
- Which platforms actually enforce a hashtag limit?
- Instagram, YouTube and Threads are the live platforms that enforce a hashtag cap — 30, 15 and 1 per post — and every other live platform enforces none.
- What happens on a platform with no hashtag limit?
- Nothing is flagged — that platform simply does not enforce a hashtag cap, so any count is fine there.
- Does this count hashtags inside a URL?
- No — the counter strips URLs first, so a hashtag-like fragment inside a link is never miscounted as a real hashtag.
- Does the counter store or send my caption anywhere?
- No — counting happens entirely in your browser as you type, and nothing is uploaded, saved, or sent to a server.
- Is this the same as the caption and character counter?
- No — the caption counter measures character length against each platform's text limit; this tool measures hashtag count specifically.
- Should I always use the maximum hashtags a platform allows?
- Not necessarily — a focused, relevant set of tags often outperforms stuffing the maximum a platform happens to allow.
