A LinkedIn post can be up to 3,000 characters, including spaces, but only about the first 200 show before "...more". Comments can be 1,250 characters, your headline 220 and your About section 2,600. Connection request notes are limited to 200 characters, and InMail messages to 1,900 with a 200-character subject.
Here's every LinkedIn limit in one place, where each number comes from, and how to make a long post fit. Checked on 10 November 2026.

LinkedIn doesn't publish every limit in its help pages: the post, comment and profile limits are enforced by its editors rather than documented. If an editor ever disagrees with this table, the editor is right. Spaces, line breaks, punctuation and emoji all count.
LinkedIn post character limit
3,000 characters per post. That's roughly 450 to 500 words, enough for a short essay.
The number that matters more is the fold. The feed shows only the first few lines, roughly 200 characters on a computer and less on a phone, then "...more". Most readers decide from those lines whether to click. Put the point, the number or the surprise in the first line, and keep the opening paragraphs short so more of it shows.
Our free character counter counts a draft against LinkedIn's 3,000, and the LinkedIn text formatter shows exactly where "...more" will fall. More in how to preview a LinkedIn post.
LinkedIn comment character limit
1,250 characters per comment. That's enough for a considered reply, and longer than most comments should be. If you need more room, for example to share a link and some context under your own post, split it over two comments or move the detail into the post itself.
LinkedIn profile limits: headline, About and experience
| Field | Limit | What actually shows |
|---|---|---|
| Headline | 220 characters | Search results, comments and invitations cut it short, so put your role and value in the first few words |
| About | 2,600 characters | The first few lines, then "see more" |
| Experience description | 2,000 characters per role | The first lines, then "see more" |
Your headline appears next to every post and comment you make, so it's the profile field most people read. Our LinkedIn text formatter works in headlines and About sections too, if you want a bold word or a bullet list.
LinkedIn message limits
- Connection request note: 200 characters. On a free account, LinkedIn lets you add a personal note to up to three connection requests a month; Premium members can personalise every invitation.
- InMail: 1,900 characters, with a required subject line of up to 200 characters. LinkedIn notes that shorter InMails tend to get more replies.
- Messages to connections have a much higher limit, so length isn't the constraint there.
LinkedIn article and newsletter limits
Articles and newsletter editions have far more room than posts: the body can run to many thousands of words, with headings, images and links. The limits that matter are the ones search engines see:
- SEO title: search results cut it off after 60 characters.
- SEO description: LinkedIn suggests 140 to 160 characters.
You set both in the article's publishing settings. Our guide to starting a LinkedIn newsletter covers the rest of the setup.
How to fit more into a LinkedIn post
- Cut the warm-up. Start with the conclusion. "I've been thinking a lot about..." spends your best 50 characters on nothing.
- Use the first comment. Put the link, the sources or a follow-up thought in the first comment under your post. Our guide to the link in the first comment explains when it helps.
- Move detail into images. A chart or a screenshot of a list says more than a paragraph and doesn't count toward the limit. LinkedIn allows up to 20 images per post.
- Write an article. If you're over 3,000 characters with nothing to cut, it's an article, not a post.
- Go easy on hashtags. They count toward the limit and no longer bring reach. One to three is plenty; here's how to use LinkedIn hashtags now.
LinkedIn vs other networks
| Network | Post limit |
|---|---|
| 3,000 characters | |
| X | 280 on a free account (details) |
| Bluesky | 300 (details) |
| Threads | 500 |
| Instagram caption | 2,200 |
If you post the same idea to several networks, write the LinkedIn version first and cut it down for the others.
Writing within LinkedIn's limits in Postbase
In Postbase, each network gets its own version of a post with a live counter, so the LinkedIn version can use its full 3,000 characters while the X version stays under 280. Add a second part and Postbase publishes it as the first comment under your post. Postbase posts to LinkedIn personal profiles, with text and up to 20 images.

Frequently asked questions
What is the character limit for a LinkedIn post?
3,000 characters, including spaces and line breaks. Only about the first 200 show in the feed before "...more", so the opening matters most.
How many characters can a LinkedIn comment be?
1,250 characters.
What is the LinkedIn headline character limit?
220 characters. Search results and comment threads show less than that, so put the most important words first.
How long can the LinkedIn About section be?
2,600 characters. Only the first few lines show before "see more".
What is the character limit for a LinkedIn connection request?
200 characters for the personal note. Free accounts can add a note to three connection requests a month; Premium members to all of them.
How long can a LinkedIn InMail be?
1,900 characters in the body, plus a required subject line of up to 200 characters.
How many characters show before "see more" on LinkedIn?
Roughly 200 on a computer and fewer on a phone. LinkedIn also cuts off after a few lines, so line breaks near the top reduce what's visible.
