What are the LinkedIn character limits?
Here is every limit in one place, with how firm each figure is. "Help page" means LinkedIn states it in its help centre. We give each page's age as LinkedIn showed it on 1 November 2026, because some pages are years old and they don't always agree.
| Field | Limit | How firm is it? |
|---|---|---|
| Post | 3,000 | Help page: Post and share updates, updated 3 weeks ago |
| Post in a group | 3,000 | Help page: General limits for groups, updated 1 year ago |
| Comment | 1,250 | Stated for group comments on the same page. We found no help page for comments on ordinary posts |
| Headline | 220 | No LinkedIn page found. Third-party testing only (see below) |
| About section | 2,600 | LinkedIn blog, not a help page: LinkedIn Talent Blog, 30 April 2024 |
| Connection note | 200 | Help page: Personalize invitations, updated 6 months ago. Premium may get 300 |
| InMail subject | 200 | Help page: Send an InMail Message, updated 7 months ago |
| InMail body | 2,000 | Same page. A Recruiter page says 1,900 |
| Article | 125,000 | Help page: Posting updates vs publishing articles, updated 3 years ago |
| Public profile URL | 3 to 100 | Help page: Manage your public profile URL |
Why do sources disagree on comments and headlines?
LinkedIn doesn't publish every limit, so most lists online come from people testing the editor. Two fields have this problem.
Comments. The groups limits page says 1,250, while an older group comments page, last updated 3 years ago, says 1,000. Third-party guides such as Eden list 1,250 for comments in general. We would plan on 1,250 and keep comments far shorter anyway.
Headlines. Brenda Bernstein reported the move from 120 to 220 in an August 2020 LinkedIn article, having tested it personally and noting it wasn't officially advertised. Hublead says the profile editor stops at 220 and LinkedIn doesn't publish the figure on a help page. Older guides still say 120, so check the date on anything you read. To test it yourself, paste 221 characters into your headline field and see where it stops.
How long can a LinkedIn connection note be?
Plan on 200 characters. LinkedIn's pages give different numbers for length and for how many notes a free account gets:
| LinkedIn help page | Shown as updated | Free accounts | Premium |
|---|---|---|---|
| Personalize invitations to connect | 6 months ago | Notes on up to 3 requests a month; up to 200 characters each | Unlimited notes; connection request limits may still apply |
| Invitation limit reached | 1 year ago | Notes on 5 requests a month | Unlimited notes |
| InMail vs personalized invitations | 2 years ago | Up to 5 notes; 200 characters | Unlimited notes; 300 characters |
So free accounts get three a month (an older LinkedIn page says five), and we would plan around three. Third-party lists split too: Hublead says 200 and Eden says 300. A note under 200 characters fits on any account, which is why our connection request templates stay under it. Our guide to the connection request limit covers the wider invitation rules. For when a note is worth using at all, see should you add a note to a connection request.
Is the InMail limit 2,000 or 1,900 characters?
It depends on which page you read. LinkedIn's InMail FAQ and its page on sending InMail both say up to 200 characters in the optional subject line and up to 2,000 in the body. Its Recruiter InMail FAQ says 200 and 1,900, and Hublead lists 1,900 too.
Keep to 1,900 and the message fits under either figure. You will rarely get close: 1,900 characters is roughly 300 words at about six characters a word, which is a long read on a phone.
How much of each limit should you use?
The limit is only how much LinkedIn accepts. It says nothing about how much people will read, so write for what shows first.
- Post. LinkedIn doesn't publish where "see more" cuts a post. Eden estimates about 210 characters on desktop and 140 on mobile, so put your point in the first line. Our text formatter counts each bold-looking letter as two characters, so styled text uses up the allowance faster.
- Headline. Lead with who you help. Our headline generator counts each draft against 220.
- About section. You get 2,600, but LinkedIn's profile advice suggests one or two paragraphs. Our summary generator gives you a structure to start from.
What should you do when you go over a limit?
Cut first, then move the rest. LinkedIn's own suggestion for a post over 3,000 characters is to write an article instead. Here is how that works on a 4,000-character draft:
| Option | What happens to the 4,000 characters | Use it when |
|---|---|---|
| Cut | Remove 1,000 and post the rest | The draft has padding, which most do |
| Comment | Post 3,000 and put up to 1,000 in your first comment, inside the 1,250 limit | The extra part is a source or a footnote |
| Article | Publish all 4,000; the limit is 125,000 | The piece needs headings and will be read later |
For anything else, write in a separate document that shows a character count, then paste. Spaces and line breaks use up characters in most counters, so leave a small margin rather than aiming for the exact figure.
Frequently asked questions
What is the LinkedIn post character limit?
3,000 characters. LinkedIn states this on its Post and share updates help page, updated about three weeks before our 1 November 2026 check. If your post is longer, LinkedIn suggests writing an article, which can run to 125,000 characters.
What is the LinkedIn comment character limit?
1,250 characters is the best-supported figure. LinkedIn's help centre states it for comments in groups, and an older group page says 1,000. We found no help page covering comments on ordinary posts, though third-party guides list 1,250 for comments in general.
How many characters can a LinkedIn headline have?
220, according to third-party testing. We found no LinkedIn help page that states it. Hublead says the profile editor stops at 220, and Brenda Bernstein reported the change from 120 in August 2020 after testing it personally. Guides that say 120 are out of date.
How long is the LinkedIn About section limit?
2,600 characters, according to a LinkedIn Talent Blog article dated 30 April 2024. We found no help page stating it. LinkedIn's profile advice suggests keeping the text to one or two paragraphs, and only the opening shows before people choose to read more.
How many characters is a LinkedIn connection note?
Plan on 200. LinkedIn's most recently updated page says up to 200 characters. An older page gives 200 for free accounts and 300 for Premium. Free accounts can add notes to three requests a month, though an older LinkedIn page says five.
Is there a LinkedIn article character limit?
Yes. LinkedIn's help centre says articles are limited to 125,000 characters. That page was last updated about three years before our 1 November 2026 check, and some third-party guides give a lower estimate, so try a test draft if you are writing something very long.
