LinkedIn character limits, all in one place

Every limit in one table

Comment length is left out on purpose. LinkedIn's Help page on comments does not state a limit, so we do not quote one.

Count your post

Paste a draft to see how close it is to 3,000 characters and to the fold. For more room to edit and a feed preview, use the free LinkedIn character counter.

The limit that matters most: "see more"

The 3,000 character cap rarely bites. The cut that shapes every post is the "see more" fold. The feed shows only the opening of a long post, and a reader has to click to see the rest.

LinkedIn does not publish where that cut falls. It depends on the screen, the app and your line breaks. On desktop it is roughly the first three lines. On a phone it comes sooner. Our own tools estimate it at roughly 210 characters on desktop, but treat that as an estimate, not a LinkedIn number.

What you can control is simple. Put the point of the post in the first line. Keep that line short enough to read whole on a phone. And make it a reason to click, not a warm up. Our guide to writing hooks goes deeper, and the post preview tool shows the fold on desktop and mobile.

Headline and About: using the room well

LinkedIn Help says your headline is "the text below your name" and that it is "displayed in search results". So it works like a title tag for you. The 220 characters are the full room, but people scanning a list of names only take in the start. Lead with who you help and how.

The About section gives you 2,600 characters. That is roughly 400 words. Use the first two lines to say what you do and for whom, because that is what shows before a reader expands it. For ideas by role, see our LinkedIn headline examples.

Invitation notes and InMail

An invitation note can be up to 200 characters. LinkedIn Help says free members can add a note to up to three connection requests per month. Premium members can add notes to all their requests, though overall connection limits may still apply.

InMail gives you 200 characters for the subject and 1,900 for the body. LinkedIn shows a counter that changes color as the message gets longer, a nudge toward short messages.

Use less than the limit

Having 3,000 characters does not mean you should use them. LinkedIn's engineers have written that the feed predicts the chance a reader will skip a post and lowers its score to match. A long post that loses people halfway gives the feed exactly that signal.

A good test: after the first line, does every paragraph earn the next one? If a paragraph only repeats the point, cut it. If the post covers two ideas, split it into two posts and schedule them a few days apart.

• Short paragraphs. One to three lines each. White space makes a long post feel shorter on a phone.
• One idea per post. LinkedIn said in March 2026 its feed tries to understand "what a post is actually about". Make that easy.
• End with one clear ask, or none. Two asks split the reader's attention.

How characters are counted

Spaces, line breaks and punctuation all count. LinkedIn does not publish exactly how it counts emoji or the styled bold letters some formatters produce. Those styled letters are separate Unicode symbols, not real bold text, and screen readers may read them oddly. If you use a text formatter, use it for a word or two, not whole paragraphs.

X counts differently. It gives some characters a weight of 2 and counts every link as 23. If you post the same idea on both networks, see the X character limit.
