How it works
To count characters against a platform limit, choose a platform above and type or paste your text — the running count, remaining characters, and a progress bar update live, computed locally with no upload.
Each platform in the dropdown enforces a different limit for a different reason: X caps posts at 280 characters to keep them skimmable, YouTube caps titles at 100 to keep them from being cut off in search and recommendation rows, and Facebook truncates posts behind a "See more" link past roughly 477 characters even though the platform accepts far more. This tool counts against whichever limit you select rather than a single generic number.
The count is by Unicode code point, not by UTF-16 code unit, which matters for emoji and other characters outside the Basic Multilingual Plane — a single emoji counts as one character here rather than the two "characters" JavaScript’s .length would report for it, matching how these platforms generally count.
Limits shift as platforms update their products, so treat the numbers here as accurate as of when this page was last checked rather than permanently fixed — if a limit looks wrong, the platform likely changed it.
FAQ
Does this count emoji as one character or two?
One. The count uses Unicode code points rather than raw UTF-16 length, which is how most of these platforms count too — otherwise many emoji would count double.
Why does Facebook show such a low limit compared to its actual post limit?
Facebook accepts much longer posts, but truncates them behind a "See more" link at roughly 477 characters in most feed contexts — that’s the practical limit for what readers see without an extra click, not a hard cap.
Are these limits guaranteed to be current?
They reflect each platform’s publicly stated limits as of when this page was last reviewed. Platforms do change these over time.
