Hashtag Limit Checker
Count hashtags against per-platform limits for Instagram, TikTok, Twitter, and LinkedIn.
About this tool
Each platform caps hashtags differently — exceeding limits truncates tags or looks spammy to algorithms.
Real-time counting as you paste prevents last-minute caption edits before posting.
How to use the Hashtag Limit Checker
- 1
Paste your caption or hashtag block into the tool.
- 2
Select the target platform to see its hashtag limit.
- 3
Adjust your tag count before posting to stay within platform rules.
Platform limits overview
Instagram allows 30 but recommends 3–5. TikTok supports many tags in caption. X works best with 1–2 focused tags.
Hashtags mid-caption count the same as trailing blocks.
Pro tips
- Count hashtags after writing caption body — edit order matters for readability.
- Use hashtag generator for fresh tag ideas within limits.
