Free LinkedIn Post Preview & Character Counter

See how your post will look in the feed, where “…see more” truncates it on desktop and mobile, and how you track against LinkedIn’s 3,000-character limit.

0 / 3,000 characters
Your post preview appears here.

The “…see more” cut is approximate — LinkedIn varies it by device, font and testing. Front-load your hook in the first 140210 characters.

Why preview your post before publishing?

The LinkedIn feed only shows the first couple of lines of a post before hiding the rest behind “…see more”. That truncated snippet is your entire pitch for the click. This tool renders your draft in a feed-style card and marks the cut so you can see, before you publish, exactly what scrollers will read.

How to use it

Paste your draft into the box. Toggle between desktop and mobile to see both truncation points — mobile cuts sooner, so it is the stricter test. Watch the character counter: it stays neutral, turns amber as you near the 3,000-character limit, and red once you go over. If you stack several blank lines, you will get a nudge, because LinkedIn collapses large gaps.

Tips for a stronger first line

  • Lead with a number, a bold claim, or an open loop — not a warm-up sentence.
  • Keep the first line short so it survives the mobile cut at ~140 characters.
  • Put your call to action and links lower down; the hook’s only job is to win the “see more” click.

Once your hook lands, use the formatter to bold it, and let Linkera help you write the next one.

Frequently asked questions

Where does LinkedIn cut off a post with “…see more”?
On desktop the feed shows roughly the first 210 characters before the “…see more” link; on mobile it is closer to 140. The exact cut varies by device, font size and testing, so treat the preview as a close approximation.
What is the LinkedIn post character limit?
A LinkedIn post can be up to 3,000 characters. This tool counts as you type and warns you as you approach and exceed the limit.
Why does my hook matter so much?
Only the first line or two show before the fold. If those characters do not earn the click on “see more”, the rest of your post is never read. Front-load the tension, the promise or the number.
Does this preview send my post anywhere?
No. Everything runs in your browser. Nothing you paste is uploaded or stored.
