LinkedIn Post Checker and Character Counter
A LinkedIn post holds 3,000 characters, but only about 210 survive on desktop and closer to 140 on mobile before "...see more" takes over.
Last updated: 2026-07-31
The LinkedIn post limit is 3,000 characters. The number worth planning around is 210, because that is roughly where the desktop feed drops in a "...see more" link and stops showing the rest. On mobile it is tighter still, closer to 140.
That makes the first two lines the entire pitch. Everything underneath is read only by people who already decided to expand it, which is why the LinkedIn posts that travel front-load the claim and leave the reasoning below the fold.
LinkedIn does not publish a hashtag cap, but the feed treats a wall of them as noise. Three to five at the end, chosen because someone might actually follow them, is the pattern that still works.

How LinkedIn compares to the other networks
The hard ceiling is rarely the number that matters. Here is where LinkedIn sits against every other network Postify publishes to, including the point each one folds your caption behind a "more" control.

LinkedIn caption tips
- Treat the first 210 characters as the whole post. That is what desktop shows before "...see more", and mobile shows even less.
- Break the line early. A one line opener followed by white space earns noticeably more expands than a dense paragraph of identical length.
- Three to five hashtags at the end. LinkedIn imposes no hard cap, but the feed rewards restraint over volume.
- If a post needs an external link, consider putting it in the first comment and saying so in the post itself.
- Your profile headline is a separate 220 character field with its own indexing. Do not spend post characters repeating what it already says.
Frequently asked questions
How many characters can a LinkedIn post have?
Three thousand characters for a standard feed post, including spaces, emoji, hashtags and mentions. Documents, polls and articles are separate formats with their own fields.
Where does LinkedIn cut off a post?
Desktop collapses the post behind "...see more" at around 210 characters. Mobile folds closer to 140. Because most LinkedIn traffic is mobile, writing to the smaller number is the safer habit.
How many characters is a LinkedIn headline?
Two hundred and twenty characters on the profile headline field. It is indexed separately from your posts and shows up next to your name everywhere on the platform, so it is worth its own draft.
How many hashtags should I use on LinkedIn?
Three to five. LinkedIn does not enforce a maximum, but hashtags spend characters from the same 3,000 and a long tag block at the end of a post visibly lowers how professional it reads.
Do LinkedIn articles have the same character limit?
No. Articles are a long-form format with a ceiling in the region of 110,000 characters, roughly thirty-five times a feed post. They are indexed by search engines too, which posts are not.
