LinkedIn post preview

How to use it

1. Paste your draft (or write directly in the editor). Nothing you type leaves your browser.
2. Switch between the Desktop and Mobile tabs. Everything after …see more is invisible until a reader clicks — click it yourself to expand, like in the feed.
3. Edit until the strongest sentence sits fully above the mobile fold, then copy the post out.

The fold decides reach

Every LinkedIn post gets judged twice. Once by the readers who see only the pre-fold fragment and decide, in about a second, whether to click …see more. And once by the feed, which amplifies posts people stopped for. A brilliant post with a weak first 140 characters performs like a weak post, because for most of the audience the fragment was the post.

That's the whole reason this preview exists: writers judge their drafts in full, but readers meet them amputated. The single most useful pre-publish habit is reading your post the way the feed serves it — cut mid-sentence, with everything you were building toward hidden behind a click.

Read your hook amputated

Look at the preview above and ignore everything you know about the rest of your post. Does the visible fragment contain one complete reason to click — a tension, a specific number, a claim that cuts against common advice? Or does it spend its ~210 characters on warm-up ("I've been thinking a lot lately about…")? The fold is the most expensive real estate you have; throat-clearing there costs more than anywhere else. If the fragment doesn't earn the click, fix the opening before touching anything else — our hook generator exists for exactly that edit, and the character counter tracks the fold as a live stat while you rewrite.

Line breaks count toward the fold

The fold is really two limits at once, and it lands on whichever runs out first: a character budget and a line budget. Every line break spends a whole line — so a hook written as three short punchy lines gets truncated earlier than the same words as one flowing paragraph, even though the character count is identical.

This preview models both. It word-wraps your draft at a typical LinkedIn feed column for the device you picked — roughly 92 characters per line on desktop, 46 on mobile — counts the rendered lines, and cuts at the character limit or the third line, whichever comes sooner. Those column widths are fixed assumptions about LinkedIn's layout rather than a measurement of your own screen, so an unusually large or small display will read a little differently. That is why pasting a break-heavy hook can shorten the visible fragment dramatically the moment you switch to the mobile tab: at mobile width the same words wrap onto more lines, and the line budget runs out long before 140 characters do. Most preview tools count only characters and quietly tell break-heavy hooks they are safe.

The usual caveat still applies, and it is not a small one: LinkedIn documents none of this. Character limits, line counts and wrap widths all shift with device, font size, zoom and whatever the UI team shipped this quarter. The model here is a good approximation, not a guarantee — if your draft leans on line breaks for rhythm, check the mobile tab and leave yourself margin. The line break fixer helps when the breaks themselves are the problem.
