LinkedIn Character Limits for Every Field

LinkedIn character limits at a glance

Where LinkedIn publishes a number, we link to its Help Center. Where it does not, we link to the most recent independent test we could find and say so. Limits can change without notice, so if a number matters, check it in the field itself before you write.

LinkedIn post character limit: 3,000

LinkedIn Help states that posts can contain up to 3,000 characters, and suggests writing an article if you need more (LinkedIn Help). The same 3,000 applies to posts in Groups (LinkedIn Help) and to the text above an image, video or document post, since that text is a normal post.

Everything counts: letters, spaces, line breaks, hashtags, links and emojis. Emojis can count as two characters or more, and the styled Unicode letters used for “bold” text on LinkedIn may also count as more than one, so a heavily formatted post fills up faster than it looks (AuthoredUp).

You rarely need the full 3,000. Most strong posts say one thing; length is a choice, not a target. Paste your draft into the free LinkedIn post preview to count characters and see how it looks before you post.

Where LinkedIn cuts off a post with “see more”

In the feed, LinkedIn shows the start of a post and hides the rest behind “…see more”. LinkedIn does not publish the cut-off, and it is not a fixed character count: it depends on the device, the screen width, line breaks and whether the post has an image or document attached.

Independent testing puts it at about 210 characters on desktop and about 140 on mobile (AuthoredUp). Line breaks can pull the cut-off earlier, because each one uses up a line of the preview.

• Put the hook in the first line, and make it a complete thought.
• Keep the first line under about 140 characters so it survives on phones.
• If you use a line break after the first line, make sure the second line still makes sense if it is cut off.

LinkedIn comment character limit: 1,250

LinkedIn lists a 1,250-character limit for comments in its Groups limits (LinkedIn Help), and independent tests in 2026 found the same limit for comments on regular posts (AuthoredUp). Some older guides say 1,750; we could not confirm that number today.

If a reply needs more than 1,250 characters, it is probably a post of its own. Write it, then link to it in a short comment.

LinkedIn profile character limits: headline, About and experience

LinkedIn does not list these limits in its Help Center, so these figures come from recent independent testing (AuthoredUp). The profile editor shows a counter as you type, which is the final word for your account.

The same logic as posts applies: put the important words first. Your headline appears next to your name on every post and comment you write, often shortened, so lead with what you do and for whom.

LinkedIn article and newsletter limits

Articles are LinkedIn’s long-form format, and newsletters are built on them. The body can run to 125,000 characters (LinkedIn Help), and the title to 150 characters by independent testing (AuthoredUp).

Use an article when a post would need more than 3,000 characters, or when you want something with headings that people can find again later.

LinkedIn Page, message and poll limits

• Company Page tagline: 120 characters. Page description: 2,000 characters (AuthoredUp).
• Connection request note: 200 characters on a free account, 300 with Premium. Free accounts can add a note to only a few requests each month (LinkedIn Help).
• Polls: questions up to 140 characters and options up to 30 characters each. You can add up to four options on desktop and Android, and up to five on iOS (LinkedIn Help).
• Direct messages: about 8,000 characters (AuthoredUp).
• Document ads: headline 70 characters, introductory text 150 (LinkedIn ads specs). These are ad limits; organic posts get the normal 3,000.

How to write a LinkedIn post that fits the limits

Character limits rarely stop a good post. What stops readers is a post that is long without a reason. A few habits keep you well inside the numbers:

1. Write the first line last. Once you know what the post says, write an opening that fits in about 140 characters and makes people tap “see more”.
2. One idea per post. If you have three points that each need a paragraph, that is a carousel or three posts.
3. Cut the warm-up. Most drafts get better when you delete the first sentence or two.
4. Use line breaks with care. White space helps on phones, but every break uses a line of the preview.
5. Format a little, not a lot. A bold line or a short list helps skimmers. Make it with the free LinkedIn text formatter, and remember styled letters may use extra characters.
6. Check before you post. Paste the draft into the LinkedIn post preview to see the length and the cut-off on desktop and mobile.

LinkedIn carousel character limits

A LinkedIn carousel is a PDF document post, so it has two text fields: the post text above it, which gets the normal 3,000 characters, and the document title, which LinkedIn requires but does not publish a limit for. Keep the title to one short line that says what the carousel is about.

Text inside the slides does not count toward any limit, because it is part of the PDF. The limit there is legibility: if a slide needs more than about 40 words, it needs to be two slides. See how to make a LinkedIn carousel for slide-writing tips, or let Postora plan and write the slides for you.
