LinkedIn Character Limits 2026: Posts, Headline, About & Articles

LinkedIn limits in full

LinkedIn is unusual in that its two most important fields sit at opposite extremes. A post allows 3,000 characters but reveals about 140 of them; a headline allows 220 and is the single piece of text that follows your name across every surface of the platform.

The 140-character decision point

In the feed, a post is collapsed after roughly 140 characters on desktop and closer to 100 on mobile, with the remainder hidden behind a "see more" control. Expanding a post is a deliberate action, and LinkedIn's ranking system treats it as an engagement signal — which means the opening lines do not merely influence readership, they influence distribution.

• •Deliver a complete, self-contained statement within the first two lines.
• •Avoid using the opening for context, credentials or throat-clearing.
• •A single line break early in the post makes the visible portion easier to read and does not reduce how much text is shown.
• •Hooks that create an obvious information gap outperform summaries, because expanding is the only way to close the gap.

Posts written as a single dense paragraph are penalised in practice rather than by policy: the visible fragment is harder to parse, so fewer readers expand, so distribution narrows.

The headline is the highest-leverage field

At 220 characters the headline is not especially long, but it appears beside your name in the feed, in search results, in comments, in messages and in notifications. It is also indexed by LinkedIn's search, which makes it the primary determinant of whether you appear in results for a given term.

Around 60 characters are visible in most contexts, so the structure that works is to lead with the role or specialism and place supporting detail afterwards, where truncation costs nothing. A headline reading "Data Engineer — streaming pipelines, Kafka, dbt | Writing about analytics infrastructure" is fully functional even when cut at 60 characters.

How LinkedIn counts characters

LinkedIn counts every character as one, with no weighting for script and no special treatment of URLs. Line breaks count as one character each, which is worth accounting for in heavily formatted posts, and emoji count as one in most cases.

URLs count their literal length, so a long tracking link consumes real space — unlike X, where every link costs a flat 23 characters. LinkedIn also replaces a pasted URL with a link preview card, and the URL text can be deleted from the post afterwards while the card remains, which recovers the characters entirely.

Articles versus posts

LinkedIn articles allow 125,000 characters, which is effectively unlimited, and support headings, images and embedded media. They are indexed by external search engines, which posts largely are not, making them the appropriate format for material with a long useful life.

Posts, by contrast, receive substantially more distribution within the LinkedIn feed. The common pattern is to publish the substantive version as an article and a self-contained summary as a post, rather than treating the post as a teaser that requires a click to make sense.

Drafting outside the composer

LinkedIn's composer shows no counter until you near the 3,000-character limit and gives no indication of where the 140-character cutoff falls. PostLen displays both the count and a preview shaped like the LinkedIn feed, and measures the same draft against X, Threads, Instagram, YouTube and TikTok at once. All processing happens in the browser.
