A LinkedIn post can run 3,000 characters — about 450 words — but the feed grants it roughly ~140 characters on mobile (about ~210 on desktop) before folding the rest behind “…see more”. Paste your draft below: the card collapses it at the mobile fold with a working toggle, the counter tracks the 3,000-character cap, and the fold status tells you the moment your hook outgrows its window.
As with all our previews, the card is generic by design — neutral glyphs, no LinkedIn branding — and the optional image stays in your browser via a local object URL, never uploaded.

Guide
LinkedIn is the rare network where long, structured posts routinely win — yet every one of them is auditioned through a keyhole. Before “…see more”, a reader sees roughly ~210 characters on desktop and only about ~140 on mobile, where most scrolling happens. This card folds at the mobile number because it’s the harsher cut: a hook that works at ~140 characters works everywhere.
The fold isn’t a published constant — line breaks shorten it, and devices and font settings shift it — so the preview marks it approximate. What doesn’t move is the source: both numbers are parsed from the same verified limits dataset as our LinkedIn character counter, so this page can never quietly disagree with it.
Treat the visible fragment the way you’d treat an email subject line: a specific claim, a tension, or a result — not a wind-up. The toggle on the card lets you read the folded version cold, which is the closest you can get to a stranger’s first impression. If the fragment still makes you want the rest, expand it and check the structure below: short paragraphs, one idea each, a question or call to action at the end.
A common failure mode the card makes obvious: the multi-line opener. Line breaks spend the fold budget fast, so a two-line poetic opening can push your actual point below “…see more” even at a modest character count.
Once the hook clears the fold and the body fits the 3,000-character cap, export if you need sign-off — Download PNG renders a simplified card (header, image, folded text) with the Canvas API, fully in-browser. For image dimensions, the card’s media slot is presentational; the verified pixel specs live in our LinkedIn post size guide, linked below.
LinkedIn usually carries the longest version of any cross-posted idea. Composing in SocialKit, you write that long original once and trim it per network in the same screen — with every platform’s count visible — instead of maintaining five diverging drafts.
At roughly ~210 characters on desktop and about ~140 on mobile, the feed folds the rest behind “…see more”. Both numbers are approximate — line breaks and device settings shift them — which is why the preview hedges the fold.
3,000 characters, on desktop and mobile alike — over-limit text can’t be published, so the counter flags any overage in red. The fold is the other limit: only the opening survives it without a click.
Because mobile is the stricter and more common case. A hook that fits ~140 characters clears the desktop fold too; testing against the generous number flatters drafts that fail where most readers actually scroll.
No — it displays via a local object URL in your browser only, and is discarded when you leave the page. Nothing is uploaded, stored, or tracked.
Logos and icon sets are trademarks, so the mockup uses neutral glyphs and generic chrome. The point is testing your hook against the fold, not producing a fake LinkedIn screenshot.
