Every social platform enforces a different character ceiling, and crossing it gets your post truncated, your hashtags chopped, or your tweet rejected outright. The Inflowave Character Counter shows your live count against every major platform in one view - Instagram captions (2,200), Instagram bios (150), TikTok captions (2,200), X/Twitter posts (280), YouTube titles (100), YouTube descriptions (5,000), LinkedIn posts (3,000), Facebook posts, Pinterest pins, and more. Paste once, see fits/no-fits across the whole stack, and rewrite to the tightest limit before you cross-post.
How it works
- 1Paste your caption, bio, post, or tweet into the text area.
- 2We count characters and words live, including emojis (each emoji is 1+ characters).
- 3A table shows every major platform limit and whether your text fits each one.
- 4Trim or rewrite until every platform you care about shows a green check.
Who uses this tool
- Cross-posters writing one caption to send to Instagram, TikTok, LinkedIn, and X simultaneously.
- Social media managers writing bios for new client accounts on every platform.
- Founders writing a launch announcement and avoiding truncation on the platform they care most about.
- Copywriters drafting Twitter/X threads where every reply is bound by the 280 limit.
- YouTube creators writing optimized titles (max 100, ideally under 70 for mobile).
- Anyone tightening a LinkedIn post to land under the "see more" fold (~210 characters on mobile).
Why this beats the generic AI tools
- ✓All platform limits in one table - no flipping between a counter and a Google search.
- ✓Counts emojis correctly, including multi-codepoint emojis like flags and skin-tone variants.
- ✓Live word + character counts so you can also tune for readability, not just limits.
- ✓Free, no signup, no card. Useful even if you never touch the rest of Inflowave.
- ✓Zero ads, zero tracking-pixel banners, zero interstitials. Just the count.

Instagram captions: 2,200 characters (~330 words). Instagram bio: 150 characters. Instagram comment: 2,200. TikTok caption: 2,200 (recently expanded from 300). TikTok bio: 80. X/Twitter post: 280 (10,000 for X Premium). X/Twitter bio: 160. YouTube video title: 100. YouTube description: 5,000. YouTube Shorts title: 100. YouTube channel description: 1,000. LinkedIn post: 3,000. LinkedIn headline: 220. LinkedIn About: 2,600. Facebook post: 63,206 (yes, really). Pinterest pin description: 500. Pinterest board description: 500. Threads post: 500. Bluesky post: 300. These shift occasionally - the counter is updated when platforms change them.
Where the practical limit is shorter than the official limit
Just because Instagram allows 2,200 characters does not mean you should write 2,200. Engagement drops sharply past ~150 words because mobile users hit the "more" truncation and most never expand. LinkedIn posts perform best around 1,200–1,500 characters; longer still works but the "see more" fold sits at ~210 characters on mobile, so your hook needs to land before that. YouTube descriptions allow 5,000 but only the first ~150 show above the fold without clicking. Use the table to check the hard limit, then write to the soft limit.
Why emojis count as more than one character
Many emojis are encoded as multiple Unicode code points. A single waving-hand-with-skin-tone emoji is technically two code points, and a family-of-four emoji can be five. Different platforms count them differently - X counts a basic emoji as 2 weighted characters, while Instagram counts code points directly. The counter uses the most conservative interpretation per platform so you never cross a limit you thought you were under. If you are working close to a limit, drop one emoji rather than dropping a word.
FAQ
What is the Instagram caption character limit?▾
Instagram captions are capped at 2,200 characters. After that, the platform truncates the post. The Instagram bio limit is much tighter at 150 characters. Most Instagram comments also cap at 2,200. Hashtags count toward the 2,200 caption limit, and Instagram allows a maximum of 30 hashtags per post regardless of character count.
What is the TikTok caption character limit?▾
TikTok captions allow up to 2,200 characters as of the recent expansion (it used to be 300, then 4,000 briefly, now standardized at 2,200). The TikTok bio is much shorter at 80 characters. Hashtags count toward the caption limit, and the algorithm favors 3–5 well-chosen hashtags over stuffing.
How many characters is a tweet?▾
A standard X/Twitter post is 280 characters. X Premium subscribers can post up to 10,000 characters per tweet, but engagement on long-form tweets is lower than on tight 280-character posts. URLs count as 23 characters regardless of actual length, and certain CJK (Chinese, Japanese, Korean) characters count as 2.
What about YouTube titles and descriptions?▾
YouTube video titles cap at 100 characters, but the practical sweet spot is 60–70 characters because mobile search results truncate beyond that. Descriptions allow 5,000 characters. The first 100–150 characters of the description show above the fold and are the highest-weighted for SEO, so front-load your keywords.
Does the counter work offline or store my text?▾
The character and word count run client-side in your browser, so the counting itself is private. We do log the platform check for product analytics but do not store your full caption text long-term. If you are working with sensitive draft content, you can disconnect from the network and the counter will still work.
