Frequently Asked Questions

How many hashtags can I use on Instagram?

Instagram allows up to 30 hashtags per feed post or reel, and up to 10 per story. Going over 30 causes Instagram to strip the caption entirely, so staying at or under 30 is essential — our counter warns you when you exceed the limit.

How many hashtags work best on TikTok?

TikTok doesn't enforce a hard hashtag count, but the entire caption (including hashtags) is limited to roughly 2,200 characters. Most viral TikToks use 3–8 targeted hashtags; piling on more can dilute the algorithm's understanding of your content.

Does Twitter have a hashtag limit?

There's no strict cap, but research consistently shows that 1 or 2 hashtags per tweet outperform posts with 3 or more. Our counter flags anything beyond 2 as over the best-practice limit for X.

How does the counter detect hashtags?

It matches any string starting with '#' followed by letters, numbers, or underscores — including non-Latin scripts. Punctuation breaks the match, which is how Instagram itself parses them.

Why does the counter show duplicates?

Instagram and other platforms treat repeated hashtags as spammy and may suppress the post's reach. The counter deduplicates case-insensitively (so #Love and #love are one hashtag) and tells you exactly how many duplicates are in your caption.

Is the Hashtag Counter free to use?

Yes — completely free, no signup, and runs in your browser. Your caption never leaves your device.
