LinkedIn Character Limits: Posts, Comments, Notes, InMail
A LinkedIn post holds 3,000 characters, a comment 1,250, an invitation note 200. Every limit LinkedIn documents, and why the fold matters more.
The short answer: a LinkedIn post can hold 3,000 characters. The useful answer is that the total rarely decides how a post performs. What decides it is the "...see more" fold, the point where the feed collapses your text. Everyone reads what sits above it, and only the people who click read the rest.
What are the character limits on LinkedIn?
Here is every limit LinkedIn states in its own Help Center, checked on October 24, 2026. If a number isn't in this table, it's because LinkedIn doesn't publish it.
| Field | Limit | What LinkedIn says |
|---|---|---|
| Post | 3,000 characters | Longer than that, LinkedIn suggests writing an article instead |
| Comment | 1,250 characters | Documented on the LinkedIn Groups limits page |
| Invitation note (basic account) | 200 characters | Only a few personalized notes per month |
| Invitation note (Premium) | 300 characters | Unlimited personalized notes |
| InMail subject line | 200 characters | Subject is required |
| InMail body | 1,900 characters | Listed in the Recruiter help section |
You can check the post limit on LinkedIn's Post and share updates page. If you need more than 3,000 characters, LinkedIn's advice is to publish an article on its publishing platform instead of cutting your post into pieces.
How many characters can a LinkedIn comment have?
1,250. LinkedIn states that figure on its general limits for LinkedIn Groups page, and it doesn't publish a separate number for comments on regular feed posts. In practice, a comment that runs past a few lines gets folded too, so the same rule applies: put your point first.
How long can a LinkedIn connection note be?
On a basic account, LinkedIn's name for a non-Premium one, each note can be up to 200 characters, according to Personalize invitations to connect. The catch is the monthly allowance. That page says a basic member can personalize up to three invitations a month, while another LinkedIn page, InMail vs. personalized invitations, says five. Both say Premium members can personalize every invitation, and the second one gives them 300 characters per note.
Two hundred characters is roughly two sentences. That's enough for one honest reason to connect, and not enough for a pitch, which is a good thing. If you want to draft notes that fit, our LinkedIn invitation note tool keeps you under the limit, and the guide to the LinkedIn invitation limit covers how many requests you can send in the first place.
What about the headline, the About section and messages?
LinkedIn's Help Center doesn't publish a character limit for the headline, the About section or regular direct messages. The Edit your headline page explains where to change it and gives no number. You'll find figures for these fields all over the web, but none of them comes from LinkedIn, so we don't present them as official. The only messaging limit LinkedIn documents is for InMail: 200 characters for the subject and 1,900 for the body.
The quickest way to know where you stand is to paste your text into our LinkedIn character counter. You pick the field (post, headline, About, invitation note, comment or message) and it counts live against the cap it applies to that field.

Why the "see more" fold matters more than the limit
LinkedIn doesn't publish where the fold falls, and it moves with the screen, the app and whether your post carries an image or a document. In our experience, it lands after the first few lines, and every line break uses up one of those lines. A hook written as three one-word lines gets folded just as fast as a full paragraph, which is the trap of posts that space out every sentence.
The fold is the most valuable spot in your post. What sits there decides whether the rest gets read.
The safest check is to look at the post the way the feed will show it. Our LinkedIn post preview renders the feed card on desktop and mobile, with the "...see more" where it will appear.
Should a LinkedIn post be short or long?
Both work, for different reasons. A short post that fits above the fold gets read in full without a click, which suits a sharp opinion, a question or a single observation. A long post asks for the click on "see more", so it suits a story, a project breakdown or a step-by-step lesson. What never works is a long post that opens slowly.
- Short post: one idea, short enough to be read in full on a phone, no link.
- Long post: the whole hook above the fold, then one idea per short paragraph, well under the 3,000-character limit.
- Either way: spend more time on the first sentence than on anything else.
Write for the fold, not for the limit
Before you post, reread only what will show above the cutoff and ask yourself one question: do these words make someone want to click, or do they assume the rest will be read anyway? If the strongest idea in your post shows up after the fold, move it up. Nobody clicks "see more" to find out whether a post gets interesting.
