LinkedIn Post Preview
A LinkedIn post preview tool shows you exactly how your post will appear in the feed before you publish — including the "see more" cutoff, mobile vs desktop differences, and how an attached image affects visible text. LinkedIn has no native preview feature, so this is the only way to check.

Why previewing your LinkedIn post matters
LinkedIn has no native post preview feature. What you see in the editor is not what your readers see in the feed — especially on mobile, where over 60% of LinkedIn users browse. On mobile, LinkedIn shows only about 140 characters before the "see more" button, compared to roughly 210 characters on desktop. And the feed displays only 3 lines of text regardless of device, so every character in your hook either earns its place or pushes the rest of the post out of view.

A post that looks perfect on desktop may show the wrong first line on a phone screen.
~140 chars
visible before 'see more' on mobile
Your entire hook has to fit into roughly 140 characters on mobile, not the 210 you see on desktop.
3 lines
is all LinkedIn shows in the feed
LinkedIn's feed truncates after approximately 3 lines. Every word in those 3 lines earns its place or doesn't.
Understanding the LinkedIn "see more" cutoff
As of 2026, LinkedIn's "see more" button is not triggered by a fixed character count — it is triggered by line count. LinkedIn shows approximately 3 lines of text in the feed before truncating. The number of characters that fit in those 3 lines depends on your device, font size, and screen width. On desktop (555px feed column) that is roughly 210 characters; on mobile (347px feed column) it falls to around 140.
Desktop
555px feed column
~210 characters
Wider column = more characters per line. Three full lines show roughly 210 characters before the cutoff.
Tablet
468px feed column
~170 characters
Slightly narrower. Lines wrap sooner, so the cutoff occurs earlier than on desktop.
Mobile
347px feed column
~140 characters
Significantly narrower. Only around 140 characters are visible before the 'see more' button appears.
What else affects where the cutoff falls?
- Line breaks: Each blank line (double return) counts as a full line. Heavy use of white space pushes content below the cutoff faster.
- Emojis: Emojis take the same visual space as a character but can slightly affect line wrapping depending on the device.
- Attached images: When a post has an image, LinkedIn typically shows only 1–2 lines of text before 'see more' — not 3.
- User font size setting: Users who have increased their device font size will see fewer characters per line, causing the cutoff to appear earlier.
Desktop vs mobile: what actually changes
Many professionals write their LinkedIn posts on desktop but most of their audience reads on mobile. Here's exactly what differs between the two views.
| Element | Desktop | Mobile |
|---|---|---|
| Feed column width | ~555px | ~347px |
| Chars before 'see more' | ~210 characters | ~140 characters |
| Lines before 'see more' | ~3 lines | ~2–3 lines (shorter) |
| Image display | Full-width in post | May crop or resize |
| Line wrap behaviour | Fewer wraps per paragraph | More wraps, earlier |
5 things to check before you publish
Run through this checklist using the preview tool above before every post.
- 1
Is your hook fully visible on mobile?
Switch to Mobile view and confirm your opening line is complete — not cut off mid-sentence. If it's truncated, tighten it to fit within ~140 characters.
- 2
Does the first line make someone want to keep reading?
Your hook is a promise. Check that it creates curiosity, reveals a benefit, or poses a question worth answering — without giving everything away before 'see more'.
- 3
Are line breaks creating awkward gaps?
Excessive white space pushes your content below the fold faster. Remove double blank lines in your hook section, and check that the structure reads naturally in the feed.
- 4
Does the post look right with an image?
If you're attaching an image, add the URL in the preview tool. LinkedIn shows fewer lines of text when an image is present — your hook may need to be shorter.
- 5
Is the character count within the 3,000 limit?
The character counter shows your current count vs the 3,000 character limit in real time. Posts that hit the limit cannot be published — trim early, not at the last minute.
Common mistakes that hurt LinkedIn post performance
Most of these are invisible in the LinkedIn editor but immediately obvious in a proper preview.
Hook cut off mid-thought on mobile
The sentence that makes your reader click 'see more' gets truncated. On mobile, your first line may only show half your intended opening. Always preview on mobile and rewrite if it's cut.
Too many blank lines at the top
Some creators add a blank line before the first sentence as a style choice — but it counts as a line in the feed, pushing your actual hook below the fold. Use blank lines strategically, not decoratively.
Hook written as a slow build-up
Starting with 'Here's a story about...' or 'I want to talk about...' wastes your first line. The hook must earn the click immediately. Lead with the most compelling part.
Desktop-optimised formatting that breaks on mobile
Long lines that look clean at 555px desktop width wrap into awkward single-word lines at 347px mobile width. Check that your sentences don't create odd wrapping patterns on mobile.
Ignoring image impact on visible text
An attached image reduces the text visible before 'see more'. If your post includes an image, your hook must be even shorter to guarantee it shows fully before the cutoff.
Not checking with post at full character count
Some people draft a short hook then add 2,800 characters below. The full post should be checked in preview — a very long post can sometimes affect how the feed renders the top portion.

Frequently asked questions
- What is the LinkedIn character limit for posts?
- LinkedIn posts have a limit of 3,000 characters including spaces, line breaks, and emojis. Posts over the limit cannot be published.
- Where does LinkedIn cut off posts with 'see more'?
- LinkedIn shows 'see more' after approximately 3 lines in the feed. On desktop that's around 210 characters; on mobile it can be as few as 140 due to the narrower column width.
- Why does my LinkedIn post look different on mobile?
- LinkedIn's mobile feed is narrower (about 347px) than desktop (555px). Lines wrap sooner, so the 'see more' cutoff appears earlier. Over 60% of LinkedIn users browse on mobile — always test the mobile view.
- Does adding an image affect the 'see more' cutoff?
- Yes. When a post includes an attached image, LinkedIn typically shows fewer lines of text before 'see more' — often just 1–2 lines. This makes your hook even more critical with visual content.
- Why should I preview my LinkedIn post before publishing?
- Previewing your LinkedIn post helps you confirm your hook is visible before the 'see more' cutoff, verify formatting looks correct on both desktop and mobile, check that your character count is within the 3,000 character limit, and catch line break or layout issues before your audience sees them. LinkedIn has no built-in preview feature, so a dedicated preview tool is the only way to see your post exactly as readers will.
- Can I preview LinkedIn posts without a third-party tool?
- LinkedIn does not have a native post preview feature. To see how your post will look before publishing, you need a third-party tool like this one. The only alternative is to publish the post and then immediately delete it — which is not recommended, as even a briefly published post can appear in some followers' feeds.
- Does this tool show the exact LinkedIn post format?
- This tool provides a close visual approximation of how your LinkedIn post will appear in the feed, including the profile card, post text with 'see more' truncation, and action buttons. The feed column widths used (555px desktop, 468px tablet, 347px mobile) match LinkedIn's actual layout. Minor differences may exist due to LinkedIn UI updates.
- How do line breaks affect the 'see more' cutoff?
- Each blank line (double line break) counts as a full line in the feed, moving content below the cutoff faster. Keep line breaks minimal in your hook section.
- What percentage of LinkedIn users browse on mobile?
- More than 60% of LinkedIn users access the platform on mobile. A hook that's visible on desktop may be cut off on mobile without optimisation.
- Should I write my LinkedIn post on desktop or mobile?
- Write on desktop for comfort, but always preview on mobile before publishing — that's where most of your readers will see it first.
- What is the best hook strategy for LinkedIn posts?
- Your first 1–2 lines are the only text visible before 'see more' on mobile. Make a bold statement, ask a direct question, or reveal a surprising fact. Avoid slow build-ups and starting with 'I'.
- Is there a difference between mobile and desktop previews on LinkedIn?
- Yes — mobile has a narrower container (~347px vs ~555px desktop), so lines wrap sooner and the cutoff may appear at a different visual point. Always check both.
