LinkedIn hides most of your post behind a see more link. On desktop the cut lands at roughly 210 characters; on mobile it comes much earlier, at around 140 characters. Everything past that point is invisible until someone chooses to expand, and most people never do.
That makes the opening lines the entire job. A post can be well argued and still fail because the strongest sentence sits below the fold. Previewing before you publish is the cheapest way to catch that.
Write for the mobile cut and the desktop cut takes care of itself.
What does the LinkedIn post preview tool do?
+
It renders your draft exactly as LinkedIn will display it, on both desktop and mobile, so you can see line breaks, spacing and the see more truncation point before you publish. Nothing is sent to LinkedIn and no account is needed.
Where does LinkedIn cut off a post with see more?
+
On desktop LinkedIn truncates at roughly 210 characters. On mobile the cut comes earlier, at around 140 characters. Anything after that point is hidden behind a see more link that most readers never click, so your hook has to land before it.
Why does my LinkedIn post look different on mobile and desktop?
+
Mobile screens are narrower, so the same text wraps across more lines and the see more cut falls earlier. A post that reads well on desktop can hide its key line on mobile. Since most LinkedIn traffic is mobile, preview both before publishing.
Do line breaks show up the same way on LinkedIn?
+
LinkedIn preserves single and double line breaks, and they count toward the truncation point. Short paragraphs with deliberate white space consistently outperform dense blocks, because they are easier to scan in a crowded feed.
Is the LinkedIn post preview tool free?
+
Yes. It is completely free, runs entirely in your browser, and needs no login. Your draft never leaves your device.
How long should a LinkedIn post be?
+
Most high-performing posts land between 150 and 700 characters, well under the 3,000 character limit. What matters more than total length is that the first 140 to 210 characters earn the click on see more.
