A LinkedIn post can hold up to 3,000 characters, including spaces. An article holds up to 125,000, LinkedIn’s group rules cap a comment at 1,250, and a personal note on a connection request up to 200. The About section on your profile takes 2,600. Some figures quoted online, such as a 220-character headline, are on no LinkedIn page we found.
Key Takeaways
- Posts: 3,000 characters. LinkedIn’s help center says that if a post runs longer, you can write an article instead.
- Articles: up to 125,000 characters, enough for a long report.
- Comments: LinkedIn lists 1,250 characters on its page of group limits, the only comment figure on its help pages we read.
- Invitations: a personal note on a connection request holds up to 200 characters. LinkedIn’s two help pages disagree on how many notes free members get each month and on the Premium length.
- Profile: LinkedIn’s own blog gives the About section 2,600 characters. Its help page for the headline gives no number.
LinkedIn character limits at a glance
The table collects every limit we could read on a LinkedIn page in October 2026, with the page each one comes from. Where LinkedIn publishes no number, the row says so instead of repeating a figure from a third-party list.
| Where you write | Character limit | LinkedIn source |
|---|---|---|
| Post | 3,000 | Help: share a post; posts vs articles |
| Article | 125,000 | Help: posts vs articles |
| Group post | 3,000 | Help: group limits |
| Comment (stated for groups) | 1,250 | Help: group limits |
| Connection request note | 200 | Help: personalize invitations |
| About section | 2,600 | LinkedIn Talent Blog |
| Headline | No number published | Help: edit your headline |
| Ad introductory text | 3,000 maximum, about 150 advised | Help: single image ad specs |
| Ad headline | 200 maximum, 70 advised | Help: single image ad specs |
| Ad description | 300 maximum, 100 advised | Help: single image ad specs |
Posts, group posts and ad introductory text stop at 3,000, and long-form writing moves to articles. Comments, connection notes and ad headlines have tighter limits.
What is the character limit for a LinkedIn post?
3,000 characters. LinkedIn’s help page on sharing posts says “posts can contain up to 3,000 characters”, and its page comparing posts with articles repeats the figure. The count includes spaces and punctuation, so a 3,000-character post is roughly 450 to 550 words of ordinary English.
That is far more than most posts need. LinkedIn shows the first lines of a post and folds the rest behind a “see more” link, and the help pages we read give no character count for where the fold falls. The useful limit is therefore the opening, which has to earn the click. Our list of 30 LinkedIn post ideas has openings that do that in a line or two, and our explainer on how the LinkedIn algorithm works covers what happens after someone reads on.
If a draft runs past 3,000 characters, LinkedIn’s own suggestion is to publish it as an article. You can also cut it into a series of posts, which suits ideas that work in parts.
How long can a LinkedIn article be?
Up to 125,000 characters, according to LinkedIn’s page on the difference between posts and articles. That is around 20,000 words, longer than any article you are likely to write. LinkedIn says all members can publish articles, and so can admins of a LinkedIn Page.
Choose an article when the piece needs headings, several images or a length that would bury a feed post. Choose a post when the point fits in a few short paragraphs. A common pattern is both: the article holds the full piece, and a short post with a strong first line tells your network it exists.
What is the LinkedIn comment character limit?
1,250 characters is the only comment figure LinkedIn publishes, on its page of general limits for groups, next to 3,000 for group posts. We found no other LinkedIn help page with a comment limit, and third-party lists apply the same 1,250 to comments on ordinary posts.
A comment that hits the cap is usually trying to be a post. When a reply needs more than a long paragraph, write it as a post of your own and mention the original author, or answer the main point in the comment and link the longer version.
How long can a LinkedIn connection note be?
200 characters. LinkedIn’s help page on personalizing invitations says each message “can be up to 200 characters”, that free members can add one to up to three connection requests a month, and that Premium members can personalize every request. An older LinkedIn help page still says five a month for free members and 300 characters for Premium.
Because the two pages disagree, plan for the stricter one: a 200-character note, and personal notes kept for the few requests where context matters. Two hundred characters is two short sentences, enough to say how you know the person and why you want to connect.
What are the character limits on a LinkedIn profile?
The About section holds 2,600 characters, according to LinkedIn’s own Talent Blog, which describes it as “an open-ended space (sort of; 2,600 characters max)”. LinkedIn’s help page for editing your headline explains where the headline appears and how to change it, but prints no character limit.
Third-party guides widely cite 220 characters for the headline, but we could not find that number on a LinkedIn page, so check the Headline field in the Edit intro window if your headline is long. As with posts, the start matters most: the headline shows in search results, and the About section shows only its opening lines before “see more”.
What are the character limits for LinkedIn ads?
For a single image ad, LinkedIn’s ad specifications allow introductory text of up to 3,000 characters but advise about 150 to avoid truncation. The headline takes up to 200 characters, with 70 advised, and the description up to 300, with 100 advised. URLs longer than 23 characters in the introductory text are converted to a short link.
An ad that uses all 3,000 characters is allowed, but LinkedIn advises about 150 to avoid truncation, so put the offer in that opening.
How does PostNext handle LinkedIn’s limit?
PostNext checks the 3,000-character limit before a LinkedIn post is scheduled. A post that is too long is stopped in the composer with the character count and a prompt to shorten it, rather than accepted and then refused by LinkedIn at publish time.
The PostNext LinkedIn scheduler publishes text posts and posts with one or more images or a GIF to personal LinkedIn profiles; Company Pages, articles, document carousels and native video are not supported yet. Its AI writer drafts posts and hashtag sets from a topic, and every draft stays editable. While you draft, the free LinkedIn post formatter shows a running count out of 3,000. For whether hashtags still help on LinkedIn, see our answer to do hashtags work on LinkedIn.
Frequently Asked Questions
What is the character limit for a LinkedIn post?
3,000 characters, including spaces and punctuation. LinkedIn’s help center states the figure on its page about sharing posts and on its page comparing posts with articles. For anything longer, LinkedIn suggests publishing an article, which can run to 125,000 characters.
How many characters can a LinkedIn comment have?
1,250. LinkedIn lists that limit for comments on its page of general limits for groups. We found no other LinkedIn help page with a comment limit, and third-party lists use the same figure for comments on ordinary posts.
What is the character limit for a LinkedIn connection request message?
200 characters. LinkedIn’s main help page on invitations also says free members can personalize up to three connection requests a month, and Premium members can personalize every request. An older LinkedIn page gives Premium members 300 characters, so plan for 200.
How many characters is the LinkedIn About section?
2,600 characters, according to LinkedIn’s Talent Blog. Only the first lines show before “see more”, so put the most important sentence first.
Is the LinkedIn headline limit 220 characters?
LinkedIn does not state a headline limit on its help page for editing your headline. The 220-character figure comes from third-party guides, and we found it on no LinkedIn page. Check the Headline field in your Edit intro window if yours is long, and lead with the words that matter in search results.
