LinkedIn504 / 3,000 Unicode code pointsfits above the fold

Counted in Unicode code points: one plain character is one, and a link costs its full length.

What LinkedIn hides, and where

The feed shows three lines and then "…see more", and three lines is a clamp on the rendered column rather than a number of characters. That is why the guides disagree: about 210 characters fill three lines in a desktop column and about 140 fill three lines on a phone. Everything a reader decides is decided inside those three lines, because expanding the post is a click they have to choose to make.

Three posts LinkedIn only half shows

  1. A greeting on line one"Hi everyone 👋" then a blank line, then the actual point.The greeting and the blank line spend two of the three visible lines. The point lands on line three and is half-read.
  2. A long URL near the topA link placed in the second sentence rather than at the end.A URL does not wrap tidily, so it takes a whole visible line to itself. Two lines of writing are left above the fold.
  3. The same post on a phoneA 190-character opening that fits the fold on a laptop.It fits three desktop lines and runs to four on a phone, so mobile readers get "…see more" mid-sentence. The preview measures the clamp at the width you are looking at instead of trusting either number.

Only on LinkedIn

  • Plain text only - no markdown, no rich text. Line breaks carry.
  • Up to 20 images in one post, or one video, never both.
  • A PDF publishes as a scrollable document carousel, which is the format that earns the dwell time here.

Questions

Is this LinkedIn post preview free?
Yes. There is no login and no upload: it runs entirely in your browser, and nothing you type or attach leaves your device.
Why does my LinkedIn post look different in the feed than in the editor?
The editor shows the whole post; the feed shows three lines. LinkedIn also renders plain text, so bold, bullets and headings pasted from a document arrive as the raw characters. What you are seeing is the feed's clamp plus the loss of formatting, and the preview here reproduces both.
Does the preview match what LinkedIn actually shows?
It is the same chrome our studio uses before a post publishes: LinkedIn's current header layout, action row and media grid, in either of LinkedIn's themes. Engagement numbers are decorative, as in every scheduler's preview.
Where does LinkedIn cut the post off with "…see more"?
LinkedIn shows 3 lines in the feed, then "…see more". Reported at about 210 characters on desktop and 140 on a phone - the same 3 lines at two widths. No platform publishes that threshold, so the preview measures its own clamp at the width you are viewing instead of trusting a character count - switch it between desktop and phone and watch the fold move.
How long can a LinkedIn post be?
3,000 characters. Counted in Unicode code points: one plain character is one, and a link costs its full length.

Where these numbers come from: our sourced LinkedIn spec page, every figure carrying its citation and the date we last checked it.
