LinkedIn Character Counter (Live Count + 2026 Limits)

A LinkedIn post can run 3,000 characters — about 450 words — but the feed shows roughly 210 characters on desktop and 140 on mobile before the “…see more” fold. Since most LinkedIn sessions happen on phones, your first 140 characters are effectively an audition for the rest of the post.

The writers who win on LinkedIn structure for that: a one-line claim or tension above the fold, short paragraphs below it, and a question or call to action at the end. Use the counter above to draft the full post against 3,000 and then re-check just your opening line against the mobile fold.

Your headline (220 characters) follows you into every comment, connection request, and search result — it is the most-seen sentence you will write on the platform. Spend it on what you do for whom, not job-title boilerplate.

The About section allows 2,600 characters, but only about the first 300 are visible before its own “see more”. Front-load the value proposition and treat the remaining 2,300 characters as supporting evidence: specifics, numbers, and a way to contact you. Switch the counter’s field selector to draft each one against its real limit.

Hashtags count toward the 3,000-character limit. LinkedIn has de-emphasized them over the years; current practice is 0–3 highly specific tags, placed at the end so they do not pollute the hook. The “exclude hashtags” toggle shows your message length without them.

Long, structured posts do well on LinkedIn — it is the rare network where 1,500+ characters routinely outperforms one-liners — which makes it the natural “long version” when you cross-post. Composing in SocialKit, you can write the LinkedIn-length original once and cut it down for X or Threads in the same screen, instead of maintaining three drafts.
