LinkedIn Post Length Checker

LinkedIn truncates posts in the feed at about 210 characters with a 'see more' button, hiding the rest until clicked. Posts that fit fully in the visible window typically earn 1.5x to 2x the engagement of longer posts because they don't require an extra click commitment from the scrolling reader.

Paste post text to see character count, where the 'see more' cutoff lands, and how much of your message is visible above the fold. The tool also flags the LinkedIn maximum of 3,000 characters for posts and 1,300 for native articles' descriptions.

The truncation cutoff varies slightly by client (web vs mobile, device width) but lands around 210 to 220 characters in the feed view. After that, LinkedIn shows '...see more' and the rest collapses until clicked. The hook — the visible portion — is what determines whether anyone reads the rest. Engagement data from LinkedIn analytics consistently shows that the first 210 characters drive most click-through behavior. The first line specifically (under 70 characters on mobile) does the heaviest lifting because it's what shows before the linebreak. The 3,000 character total limit caps how long a single post can run; native articles published through LinkedIn's article tool have a 125,000 character limit and a different visibility model.

A worked example. A post starting 'I learned three lessons managing a $50M product budget at [Company] — and they apply to anyone running a team.' That's 113 characters in the hook — a strong first line that promises specific takeaways. Continue with three short paragraphs, each 200 to 300 characters, separated by line breaks. The total post hits 1,200 characters with 6 paragraphs, well under the 3,000 limit, with white space that reads quickly. The first 210 characters cover the hook and the start of lesson one, encouraging the click to expand. By contrast, a 1,200 character post written as a single dense block with no paragraph breaks performs measurably worse despite identical content — readers bounce off the wall of text in the visible window before clicking expand.

Limitations and platform-specific behaviors. LinkedIn's algorithm rewards 'dwell time' — the seconds users spend reading and engaging with a post. Long posts that perform well usually have several short paragraphs with line breaks, which feels like more content but reads quickly. Density matters more than character count. A 1,500-character post with 6 paragraphs of plain English outperforms an 800-character wall of dense text most of the time. Hashtags count toward the 3,000-character cap and the 210-character pre-truncation visible space; most creators put 3 to 5 at the very end so they don't crowd the hook. Mentions (@person, @Company) hyperlink in the post and notify the mentioned account, which can boost early engagement if they reshare. External links are de-prioritized by LinkedIn's algorithm relative to native content; the workaround many creators use is to put the link in the first comment rather than the post body.
