LinkedIn post preview

The preview runs a short rule in your browser. It splits your draft on line breaks and takes lines from the top until it has three lines or 210 characters, whichever comes first. If that leaves any of your text out, it shows the opening followed by "…see more". Click it to expand the full post, the way you would in the feed.

A few details of that rule are worth knowing, because they change what you see:

• A blank line is a line. A one-line hook followed by an empty line uses two of the three lines, so only one more line shows.
• A long paragraph with no line breaks is cut at 210 characters, even mid-word.
• The 210 is measured in UTF-16 code units, so a Unicode bold or italic letter from the LinkedIn text formatter uses two of them. A styled opening reaches the cut sooner.
• The character meter under the draft counts graphemes against 3,000, separately from the preview.

LinkedIn doesn't publish a fixed cut-off point in its Help pages that we could find, and it would be hard to: the feed truncates by rendered lines, and how many words fit on a line depends on screen width, font size, the app versus the browser, and the length of each word. A line that fits in one row on a laptop can wrap to two on a phone, which pushes later lines below the fold.

Treat 210 characters and three lines as a planning number, not a guarantee. The check that matters is the published post on your own phone, ideally before many people have seen it.

The same information, laid out three ways, run through this preview's rule. The text is about our retry schedule, which is real: failed posts retry after 30 seconds, 2 minutes, 10 minutes, 30 minutes and 2 hours.

• Short paragraphs with blank lines between them (179 characters): the preview shows the first sentence, the blank line and the schedule line, 120 characters in all. The third paragraph is hidden. The point is visible, but the blank line cost a whole line.
• The same sentences on consecutive lines with no blank lines (214 characters): three full lines show, 177 characters, and only the fourth line is hidden. More fits, at the cost of a denser block.
• One long paragraph (252 characters) that opens with "We spent a while thinking about how retries should work": the cut lands at 210 characters, in the middle of the word "roughly", before the reader learns there are five retries. The opening is spent on preamble.

These are editing habits, not rules backed by data. LinkedIn's ranking isn't public and we have no engagement numbers of our own. What the preview does show you is which words a reader gets before deciding whether to tap.

• Put the news or the claim in the first sentence. "Our API now retries failed posts five times" tells the reader what the post is about; "We spent a while thinking about" doesn't.
• Finish the first sentence before the cut. A sentence that breaks mid-thought at "see more" reads as a teaser, and some readers won't tap.
• Name the specific thing: the product, the number, the result. Specifics survive truncation better than setup.
• Spend blank lines on purpose. One after the hook makes it stand out; two in the first three lines leaves almost nothing visible.
• If you bold anything, bold the hook or a short label, not the whole opening. Styled letters use more of the 210-character estimate and some screen readers skip them.
• Don't hold the link or the call to action until the end if it is the point of the post. Many readers only see the opening.

Run through this with the draft in the preview:

• The first line makes sense on its own, without anything below the cut.
• No more than one blank line in the first three lines.
• Hashtags, names and keywords are in plain text, not Unicode bold.
• Lists use line breaks, one item per line, so they scan on a phone.
• The total is under 3,000 characters, with room to spare if the post uses a lot of styled text.
• Any link is one you have opened from the draft, and it is placed where readers will reach it.
• You have opened the published post on a phone to check the real cut.

LinkedIn Help (read Nov 1, 2026) says a post can be up to 3,000 characters. That is a lot of room compared with the opening: this preview's 210-character estimate is 7 percent of it. Length is rarely the problem. The opening is.

The meter in this tool counts graphemes, the characters you see, which is the same way our API counts LinkedIn text before posting. A draft over 3,000 is rejected by our API's preflight check with text_too_long and the exact number to cut, before anything is sent to LinkedIn. Details, including how styled letters and emoji count, are in our LinkedIn character limit guide.

If posts go out from a script, an app or an AI agent, the opening still matters, and nobody is looking at a composer. Our API's dry_run option runs the same preflight checks (length, media, duplicates, daily caps) and returns the issues without publishing, so a pipeline can catch a too-long draft before it reaches LinkedIn. LinkedIn posting to personal profiles is live; see the LinkedIn API page for how it works and Schedule LinkedIn posts for timing posts with scheduled_at.
