Quick answer
Posts, comments, headline, About, experience, messages, articles and company pages, plus how much of each people actually see before the fold.
A LinkedIn post can be up to 3,000 characters, a comment up to 1,250, your headline up to 220 and your About section up to 2,600. The limit is rarely the problem, though. What matters more is how much people see before LinkedIn cuts the text off: about 210 characters of a post on desktop and roughly 140 on a phone. This page lists every limit we could confirm as of September 2026 and what to do with the space.
All limits at a glance
These are the maximums LinkedIn enforces in its editors as of September 2026. LinkedIn changes some of them without announcing it, so if a field stops you early, trust the editor over any list, including this one.

Pro tip: Paste a draft into the free LinkedIn character counter before you post. It shows the count and where the 'see more' fold lands, so you can fix the first lines instead of guessing.
Posts and the 'see more' cut-off
The 3,000-character post limit works out to roughly 400 to 500 words. Line breaks and spaces count, and so do emoji.
The number that shapes your post is the fold. On desktop LinkedIn shows about 210 characters before the 'see more' link. On the mobile app it's closer to 140, and fewer if your opening uses several short lines, because each line break eats vertical space. Everything past the fold only gets read if the first lines earn the tap.
Length itself isn't a penalty. An AuthoredUp analysis of about 372,000 posts found that posts between 1,300 and 2,500 characters had higher median engagement than posts under 400 characters. Long posts do well when the opening is strong and the rest is easy to scan.

We cut our onboarding from 14 steps to 4 and activation went from 22% to 41%. Here's what we removed, and the one step we almost removed but kept:
Profile fields
Your headline allows 220 characters, but search results and comment threads usually show only the first 60 to 70. Put your role and who you help in that first stretch, and use the rest for proof or keywords.
The About section allows 2,600 characters, and about 300 show before 'see more'. Treat those 300 characters like a post opening. Each role in your experience section gets up to 2,000 characters of description, which is plenty for three or four results with numbers.
Recommendations you write for someone else can run to 3,000 characters. Shorter ones that name a specific project tend to read as more credible than long general praise.
- Headline: 220 max, about 60 to 70 visible in search and comments
- About: 2,600 max, about 300 visible before 'see more'
- Experience description: 2,000 per role
- Recommendation: 3,000
Connection notes, messages and InMail
Free accounts get 200 characters for a connection request note, and Premium accounts get 300. Free accounts can also send only a limited number of personalised notes each month, so it's worth making each one specific.
Regular messages to your connections can be up to 8,000 characters. InMail, the paid message type for people outside your network, allows a 200-character subject and a body of about 2,000 characters.
Hi Priya, your post on pricing pages for dev tools changed how I wrote ours. I run growth at a small API company and would like to follow your work. No pitch, promise.
Articles, newsletters and polls
LinkedIn articles, which newsletters are built on, allow a 150-character title and a body of roughly 110,000 characters. That's far more than any reader needs; most useful articles land well under 2,000 words.
Polls allow a 140-character question and up to four options of 30 characters each. The 30-character options are the tight constraint, so write the options first and the question second.
Company pages
A company page tagline allows 120 characters and the About (overview) section allows 2,000. Posts from a company page follow the same 3,000-character post limit as personal posts.
What counts as a character
Every letter, number, space, punctuation mark and line break counts as one character. Most emoji count as two, because LinkedIn's editor counts them the way browsers store them, and some combined emoji such as family or flag emoji count as four or more.
Unicode 'bold' and 'italic' letters from font generators also count as two characters each, and screen readers often read them out letter by letter. Use them for a word or two at most.
Pro tip: If a post is sitting at 2,990 characters, check it for decorative emoji and styled letters first. They are often what pushes it over.
