How to Use the Post Preview

  1. 01

    Write or Paste Your Post

    Type your LinkedIn post or paste a draft. The preview updates in real time as you type. Set your name and headline, and pick an attachment.

  2. 02

    Switch Views

    Show Desktop, Mobile, or Both side by side. Switch to dark mode to preview for people using LinkedIn's dark theme.

  3. 03

    Check the See More Cutoff

    The preview shows roughly where LinkedIn truncates your post — about 210 characters on desktop and 140 on mobile, within about 3 lines. Make sure your hook fits before the cutoff.

Understanding the See More Cutoff

LinkedIn shows only the first few lines of a post in the feed. Here's the same hook on each device:

Desktop (~210 characters)

I spent 3 years building the wrong thing. Here's what I wish someone told me about product-market fit before I wasted $200K and 10,000 hours on a startup nobody wanted...…more

On desktop, LinkedIn shows roughly 210 characters (about 2-3 lines) before “see more”. This is where your hook needs to live.

Mobile (~140 characters)

I spent 3 years building the wrong thing. Here's what I wish someone told me about product-market fit before I wasted $200K and 10,000 hours…more

On phones, only about 140 characters show. Your hook must be even tighter for mobile readers.

Pro tip: Write your hook to fit within 140 characters. If it works on mobile, it works everywhere. The preview shows you roughly where the cut happens.

What This Preview Shows You

  • Realistic Layout

    Your post in a LinkedIn-style card with avatar, name, headline, timestamp, and action buttons — as it appears in the feed.

  • Desktop & Mobile Views

    Switch between desktop (full width) and mobile (narrow) to see how formatting, line breaks, and text length behave on each device.

  • Dark Mode Preview

    Many people use LinkedIn in dark mode. Preview your post in both light and dark themes to make sure it reads well in both.

  • Attachment Simulation

    See how your post looks with an image, link card, document, or text only. Link previews show the title and domain.

  • See More Indicator

    The approximate cutoff is shown. Click “more” in the preview to expand, just like on LinkedIn.

  • Optional Reaction Counts

    Add your own like, comment, and repost numbers for mockups and presentations — off by default, never invented.

Optimizing Posts for the Feed

  • Hook in the First Line

    The first ~140 characters decide if people tap “see more” on a phone. Lead with tension, a number, a bold claim, or a question. Never start with “I am excited to announce…”.

  • Short Lines on Mobile

    Many LinkedIn members read on phones, where long lines wrap awkwardly. Keep sentences short and use line breaks — the mobile preview shows you how it'll look.

  • Preview with Images vs Text-Only

    Posts with images, links, and documents get different layouts than text-only posts. Preview the one you'll actually publish.

  • Check Dark Mode

    Some emojis and Unicode characters are hard to see in dark mode. Always preview in both themes, especially if you use formatted text or special characters.

  • Mind the Character Count

    LinkedIn allows 3,000 characters. Most effective posts are much shorter — enough to make one point well. Keep your key message above the fold.

  • Link Cards Change the Layout

    When you include a link, LinkedIn can show a preview card with title, image, and domain, which pushes your text into a smaller space. Many creators put links in the first comment instead.

6 Feed Mistakes the Preview Catches

  • One long first paragraph

    Add a line break after your hook so it stands alone.

  • Hook longer than a phone screen

    Get it under ~140 characters.

  • Only checking on desktop

    Check mobile first — that's where the fold is tightest.

  • Emojis that vanish in dark mode

    Preview in dark mode before posting.

  • A link card pushing text down

    Try the link in the first comment instead.

  • Posting the first draft

    Preview, read it as a stranger would, then publish.

  • Students

    See how project and certificate posts look.

Tutorials & Help

Pro Tips

  • Preview mobile first

    The phone fold is the tightest — design for it.

  • Use “Both” view

    One glance shows the desktop and mobile fold.

  • Test your emojis in dark mode

    Dark emojis can disappear on a dark background.

  • Mock up for clients

    Turn on reaction counts only when you're making a mock-up.

Frequently Asked Questions

How accurate is this preview?

The preview recreates LinkedIn's feed layout, spacing, and “see more” behavior. The cutoff points (about 210 characters on desktop and 140 on mobile, within roughly 3 lines) are approximate — LinkedIn adjusts based on line breaks, fonts, and screen size.

Why do I need a post preview tool?

What looks good in the compose box often looks different in the feed — especially the “see more” cutoff, line breaks, and mobile formatting. A preview lets you fix that before you publish.

Does LinkedIn have a dark mode?

Yes. LinkedIn offers a dark mode on web and in its apps. The dark preview helps you check that your formatting, emojis, and special characters are readable in both themes.

How many characters show before 'see more'?

Approximately 210 characters on desktop and 140 on mobile, and usually no more than about 3 lines. Line breaks use up the space fastest. The safest approach: make your hook work within 140 characters.

Can I preview with an image or link?

Yes. Choose Image, Link, or Document. Images you choose stay on your device — they're shown with a temporary local link and never uploaded.

Is this tool free?

Yes, completely free with no login required. Preview unlimited posts on desktop and mobile, in light and dark mode. Your draft is saved automatically.

Is my image uploaded anywhere?

No. The image is read by your browser and shown with a temporary local URL. It isn't sent to our servers or saved.

Why are reaction counts off by default?

Because they're made up until your post is live. You can switch them on and type numbers for a mock-up or presentation — they're never filled in for you.

Can I see desktop and mobile at the same time?

Yes. “Both” shows the desktop and mobile versions side by side, so you can check the fold on each at once.

What do the checks under the editor mean?

They flag the issues that show up in the feed: over 3,000 characters, a first line too long for phones, one long paragraph that hides your point, more than 5 hashtags, and links in the post body.

Does the preview show hashtags and mentions as links?

It shows them as plain text. On LinkedIn they'll appear as links; the layout and length stay the same.

How is this different from the Post Writer?

The Post Writer helps you write and score a post. The Post Preview is the final visual check: how it looks on each device and theme, with attachments, and where it's cut off.
