A LinkedIn post can be up to 3,000 characters. If you need more room, LinkedIn's own advice is to write an article instead, which allows up to 125,000 characters.
LinkedIn's limits are generous for posts but tighter elsewhere, especially in groups. Here are the numbers LinkedIn publishes, and how to work with them.
The limits at a glance
| Where | Limit |
|---|---|
| A post | 3,000 characters |
| An article | 125,000 characters |
| A post in a group | 3,000 characters |
| A comment in a group | 1,250 characters |
| Mentions in one group conversation | 20 |
Posts vs articles
LinkedIn's help centre puts the difference simply. Posts let you share expertise, experiences and anecdotes, and any post you share goes out to your connections' feeds. Articles are typically longer and are limited to 125,000 characters, and they can be published by members and by admins of a LinkedIn Page. If a post runs past 3,000 characters, LinkedIn suggests turning it into an article on its Publishing Platform.
My take: most posts should never get near 3,000. The limit is a ceiling, not a target. If you're constantly cutting to fit, that's usually a sign the piece wants to be an article, or two posts. There's another difference worth weighing. A post goes out to your connections' feeds, while an article is a standing piece of writing you can point people to again and again. If what you're writing is reference material you'll want to share for months, it belongs in an article even if it would squeeze under 3,000 characters.
The group limits most people don't know
Groups have their own rules, and they're stricter on volume than on length. LinkedIn's group limits page lists:
- Up to 15 posts a week in any one group.
- Posting in up to 20 groups a week.
- 60 posts in total across all groups.
- Comments of up to 1,250 characters.
LinkedIn also notes that the post character limit change in groups is rolling out gradually, so not everyone may see it at once.
Group limits beyond characters
| Group limit | Number |
|---|---|
| Members in one group | 3 million |
| Groups you can belong to | 100 |
| Owners per group | 10 |
| Managers per group | 20 |
| Groups you can manage | 30 |
| Pending join requests at once | 20 |
If you run a community on LinkedIn, the posting caps are the ones that shape your plan. At 15 posts a week in a single group, you can't post several times a day there, so pick your best pieces for the group and keep the rest for your own feed.
Do spaces and emoji count?
LinkedIn's help pages state the limits in characters without carving anything out, so plan as though everything you type counts towards the 3,000: letters, spaces, line breaks, hashtags and emoji. The safest habit is to draft somewhere that shows a running character count, then paste the finished post into LinkedIn. If LinkedIn won't let you post, you're over; trim the longest paragraph first rather than cutting your opening or your call to action.

How to write for the limit
- Put the point in the first two lines. Longer posts are shortened in the feed with a 'more' link, so the opening has to win the click.
- Use short paragraphs and white space; characters spent on line breaks are worth it for readability.
- Save detail for the comments only if it adds something; group comments cap at 1,250 characters.
- Past 3,000 characters, publish an article and share it with a short post.
My verdict
Three thousand characters is plenty for one good idea. Write the post, cut it by a third, and see if it reads better. Usually it does. For openings that stop the scroll, my hook and headline swipe file is a good place to start, and these LinkedIn statistics show what's working on the platform now.
