LinkedIn Post Preview
See exactly where your post gets folded on desktop and mobile before you publish, so the hook never dies mid-sentence.
LinkedIn post previewSimulated feed card using our documented cut model. Nothing uploads.
The preview appears as you type.
Model documented in the code and reviewed 2026-07: desktop cuts at 3 lines or ~210 characters, mobile at 2 lines or ~140, whichever comes first. LinkedIn adjusts these over time; treat the preview as a close approximation, not a pixel promise.

Example, fictional draft
Draft opener: "We spent 6 months building a feature nobody used. Deleting it taught us more than shipping it. Here is what the data showed us about..."
Mobile verdict: cut by the length rule after "taught us", 41 characters into the third sentence. The payoff word "data" is behind the fold. Moving the number forward fixes it.
How it works
-
Paste your draft
The simulated feed card renders as you type.
-
Toggle desktop and mobile
The fold lands in different places; check both before publishing.
-
Rework the opener
The status line tells you which rule cut you and how much is hidden. Edit until the hook survives.
What this tool does and does not do
It does
- Shows where "...see more" cuts your post on desktop and mobile
- Tells you which rule cut you: the line rule or the length rule
- Uses a documented, dated cut model (in the code, not folklore)
- Runs entirely in your browser with no LinkedIn connection
It does not
- Promise pixel-identical rendering of the live feed
- Predict reach, impressions or engagement; nothing outside LinkedIn can
- Post, schedule or touch your LinkedIn account in any way
- Store your drafts; leaving the page erases them
What is the LinkedIn "see more" fold?
The feed shows a teaser of every post and hides the rest behind "...see more". That teaser is the only part guaranteed an audience; everything below it is opt-in. The fold is therefore the most valuable real estate in the post, and most drafts spend it on warm-up sentences written before the author knew their point.
How do I preview a LinkedIn post before publishing?
Paste the draft above. The card shows the visible teaser and marks the cut; the status line reports which rule fired and how many characters are hidden. Check mobile especially, since its fold arrives earlier and most reading happens there. Then edit until your strongest material sits above the line.
The two rules that decide your fold
Our documented model, reviewed 2026-07, applies whichever cuts first:
- The length rule. Roughly 210 characters on desktop, 140 on mobile, cut back to the previous word boundary so no word is split.
- The line rule. Three lines on desktop, two on mobile. Every line break you type counts toward it, which is how dramatic one-word-per-line openers fold themselves after a dozen words.
These are constants in our code with a review date, not scattered guesses. When LinkedIn shifts them, we change one line and this page in the same commit.
Writing for the fold, honestly
The fold rewards front-loading, and front-loading is just editing discipline. Three moves cover most cases:
- Promote your best sentence. Most drafts bury the strongest line in paragraph two. Move it to word one; the context it "needed" usually turns out optional.
- Put the number where it can be seen. "We cut churn 22%" above the fold beats "Let me tell you about our churn journey" anywhere.
- End the teaser mid-tension. If the cut lands right after a claim and before its explanation, "see more" does its job. The preview lets you place that cut deliberately.
What we refuse to claim about previews
A preview cannot tell you how a post will perform, and tools implying their preview predicts reach are decorating a guess. What a preview can do is mechanical and real: show the fold, protect the hook, save you from publishing a teaser that ends in "and the most important thing is". That is the whole promise here, kept locally in your browser.
Frequently asked questions
How many characters show before "see more" on LinkedIn?
In our documented model, reviewed July 2026: about 210 characters or 3 lines on desktop, about 140 characters or 2 lines on mobile, whichever limit hits first, cut at a word boundary. LinkedIn tunes these numbers over time, which is why ours live in one dated constant in the code instead of being folklore. Pair this with the character counter for the hard field caps.
Why does my post get cut earlier than the character count suggests?
Line breaks. The fold also triggers on lines: three on desktop, two on mobile. A post that opens with three short dramatic lines hits the line rule long before the character rule. The preview tells you which rule cut your draft, so you can rebalance.
Is this preview pixel-identical to the real LinkedIn feed?
No, and we say so on the widget itself. It is a close simulation built on a documented cut model, good enough to catch a hook dying mid-sentence. Fonts, exact widths and LinkedIn A/B tests vary. Tools claiming pixel-perfect previews of a feed they do not control are overselling.
What should go above the fold in a LinkedIn post?
The reason to click "see more": a sharp claim, a number, a question, or the start of a story with tension. What should not: throat-clearing ("I have been thinking a lot lately..."), which spends the fold on nothing. The hook generator exists for exactly this first-line problem.
Do line breaks help or hurt reach?
Nobody outside LinkedIn can measure that honestly, so we will not pretend. What is checkable: breaks change where the fold lands and how scannable the post is. White space that groups ideas helps reading; a break after every four words reads like a bot wrote it. The line break formatter keeps whatever spacing you choose intact.
Does the preview tool post anything to LinkedIn?
No. It has no connection to LinkedIn at all: no login, no API, nothing sent anywhere. It renders your text into a simulated card in your browser and that is the entire trick. Your drafts stay on your device.
