Cómo usar: Social Media Character Counter

  1. Write or paste your post. Your draft is kept in this browser so you don’t lose it.
  2. Check the bars: green fits, orange is close to the limit, red is over.
  3. Watch the notes for “see more” cut-offs — the first line before the fold is what most people read.
  4. For X, links always count as 23 characters and emoji count as 2, exactly like X’s own counter.

Limits change from time to time and “see more” positions depend on the device, so treat the fold values as guides.

Why X counts differently

X uses weighted counting: most Latin characters count as 1, but emoji, Chinese, Japanese and Korean characters count as 2, and every link is shortened to a t.co URL that always counts as 23 characters — however long or short the original is. A post with two links therefore has 234 characters left for text, not 280.

Write for the fold

On LinkedIn and Instagram only the first line or two are visible before the “…see more” link. Put the hook there: a clear statement, a number or a question. Formatting like bold isn’t supported natively — the Bold Text Generator creates Unicode bold and italic text that works in posts (use it sparingly for accessibility). For search snippets rather than social posts, the SERP Preview checks title and description length in pixels, and the Word Counter handles longer texts.

Preguntas frecuentes

What is the character limit on X (Twitter)?
280 characters for standard accounts, counted with weights: links are always 23 characters, and emoji and CJK characters count as 2. X Premium subscribers can post up to 25,000 characters.
How many characters show before “see more” on LinkedIn?
Roughly the first 210 characters (about two to three lines) on desktop, often less on mobile. Line breaks also push text below the fold.
Do emoji count as one character?
It depends. Bluesky counts graphemes (one emoji = 1). X counts most emoji as 2. Many other platforms count UTF-16 code units, where some emoji count as 2 or more — which is what the “Characters” stat shows.
Is my text saved?
Only in your own browser’s local storage so the draft survives a reload. It’s never sent to a server.
