Compose
LinkedIn strips markdown, so these swap in look-alike Unicode characters. They are not readable by screen readers — use them for a word or two, never a whole post.
Hook preview — everything before the fold
Starter structures
Shapes to adapt, not posts to publish as-is.
Feed preview
A close approximation, not a pixel-exact copy — fonts, spacing and the exact cut point vary by device and change over time.

Reactions & fold settings
These are for mock-ups only — the tool cannot know or predict real engagement.
LinkedIn has changed these thresholds before, so they are adjustable rather than baked in.
Post analysis
Your draft never leaves this browser and this tool cannot post for you. It is not affiliated with, endorsed by or connected to LinkedIn.
Why the "See More" Fold Decides Everything
A LinkedIn post is not shown in full in the feed. It is collapsed after a few lines, with the rest hidden behind …see more. Someone scrolling sees only that opening — so the first line is not an introduction to your post, it is your post as far as most readers are concerned.
That has three practical consequences:
- Front-load the point. If the interesting part is in paragraph three, almost nobody reaches it.
- Blank lines are expensive. The collapsed view is limited by lines as well as characters, so an empty line after a short opener can cost you most of your visible space.
- Mobile cuts earlier. The mobile feed shows noticeably less than desktop, and most LinkedIn browsing is mobile — so preview the mobile width, not the desktop one.
The previewer marks that cut point in both the composer and the feed card, so you can see the hook shrink or grow as you edit rather than finding out after you publish.
LinkedIn Post Limits at a Glance
| What | Limit | Notes |
|---|---|---|
| Post body | 3,000 characters | A hard platform limit. The counter turns red past it. |
| Desktop fold | ~210 characters | An approximation. Adjustable in the tool because LinkedIn changes it. |
| Mobile fold | ~140 characters | Also approximate, and the one that matters most. |
| Visible lines | ~3 lines | Whichever comes first — lines or characters — ends the preview. |
| Hashtags | No hard cap | Three to five is the range most commonly recommended. |
| Poll options | 4 options | The previewer shows a maximum of four. |
| Markdown | Not supported | Bold and italic only exist as look-alike Unicode characters. |
| Blank lines | Collapsed | Runs of three or more are tightened when published. |
Every figure marked as an approximation is exactly that. LinkedIn does not publish these thresholds and has changed them more than once, which is why the fold settings in this tool are editable rather than fixed.
Writing a Hook That Survives the Fold
State the point, then explain it. "Excited to share…" spends the entire visible space saying nothing.
A number, a date or a specific outcome earns a click. Abstractions do not.
Complete enough to make sense, incomplete enough to be worth expanding. Not clickbait — a real reason to continue.
A short first line survives both the character and the line limit, on every device.
Hashtags in the opening burn visible characters that could have carried meaning.
If the hook works at the mobile fold it works everywhere. The reverse is not true.
About Bold and Italic Text on LinkedIn
LinkedIn has no formatting controls and strips markdown, so real bold text does not
exist in a post. What circulates instead is a trick: substituting letters for
look-alike characters from the Unicode Mathematical Alphanumeric Symbols block. The
letter B becomes 𝐁 — a different character that happens to look bold.
This tool provides that substitution, and it is worth being clear about the cost:
- Screen readers cannot read it properly. Depending on the software, styled text is announced character by character, read as "mathematical bold capital B", or skipped entirely. A whole post in Unicode bold can be genuinely inaccessible.
- It is not searchable. Search does not match styled characters to their plain equivalents, so a styled keyword stops being a keyword.
- It can render as boxes. Devices with incomplete font coverage show tofu squares instead of letters.
Used for a single word or a short label it is a reasonable trade. Used for headings throughout a post it makes your writing unreadable to part of your audience. The analysis panel flags any post that contains styled characters for exactly this reason.
Who This Is For
Check the hook before posting, without publishing and deleting to see how it looked.
Review a draft against the fold and the character limit before it goes into the schedule.
Preview an announcement or a "open to work" post so the important line is the visible one.
Show a client exactly how their post will appear, with their name and headline on the card.
Make sure the role and location survive the fold instead of sitting behind see more.
An attachment changes the card layout — preview the type you will actually publish.
Frequently Asked Questions
What is a LinkedIn post previewer?
It is a tool that renders your draft as it will appear in the LinkedIn feed, before you publish. The main thing it shows is where the feed collapses your post behind see more, so you can tell how much of your opening is actually visible to someone scrolling.
How many characters before LinkedIn cuts a post?
Roughly 210 characters on desktop and about 140 on mobile, after which the post collapses behind see more. Those figures are approximations: LinkedIn has changed them more than once and the real cut also depends on line breaks and screen width, so the tool lets you adjust the threshold.
What is the LinkedIn character limit for a post?
3,000 characters for the post body. That is a hard platform limit, and the counter in this tool turns red once you pass it. Comments and article bodies have different limits.
Why does my post get cut off with see more?
The feed shows only the first few lines of every post so more posts fit on screen. Anything past that point requires a tap. This is why the opening line matters far more than the rest, and why the previewer marks the cut point.
Do line breaks count towards the fold?
Yes. The collapsed view shows a limited number of lines as well as a limited number of characters, so blank lines are expensive. A post with a blank line after a short opening can be cut much earlier than its character count suggests.
How do I write bold text on LinkedIn?
LinkedIn strips markdown, so there is no real bold. What people use instead is a set of Unicode characters that look bold. Select text in the composer and apply the Bold style and the tool substitutes those characters for you.
Is Unicode bold text bad for accessibility?
Yes, and it is worth knowing before you use it. Screen readers announce these characters oddly or skip them entirely, so a heading in Unicode bold can be unreadable to someone using assistive technology. They are also not indexed properly by search. Use them for a word or two, never for a whole post.
How many hashtags should a LinkedIn post have?
Around three to five is the range most commonly recommended, and the tool flags a post with more than ten. Hashtags help the post reach beyond your immediate network, but a wall of them reads as spam to human readers.
Does the previewer show my post exactly as LinkedIn will?
It is a close approximation, not a pixel-exact copy. Fonts, spacing and the fold position all vary with device, browser and LinkedIn's own changes. Treat it as a reliable guide to length and structure rather than a guarantee of exact rendering.
Can I preview an image, carousel or poll post?
Yes. Switch the post type between text, single image, carousel, video, poll and link share. Each changes the card layout, and an attachment pushes the text further up, which is worth seeing before you publish.
Is my post uploaded anywhere?
No. Everything runs in your browser. The draft autosave writes to your own browser storage only, and nothing is sent to a server or to LinkedIn.
Does this tool post to LinkedIn for me?
No. It has no connection to your account and cannot publish, schedule or read anything. Copy the finished post and paste it into LinkedIn yourself.
Will my line breaks survive when I paste the post?
Single and double line breaks paste through fine. Runs of three or more blank lines get collapsed when the post is published, so the spacing may tighten slightly compared with what you typed.
What makes a good LinkedIn hook?
Something that is complete enough to make sense on its own and incomplete enough to be worth expanding. A concrete claim, a surprising number or a short story opening all work. Vague throat-clearing like Excited to share does not, because it says nothing before the fold.
Can I save a draft?
Yes. The tool autosaves to your browser's local storage as you type, and offers to restore it next time rather than overwriting whatever you are working on.
Is this LinkedIn post previewer free?
Yes. It is free, needs no account and has no limits. This tool is not affiliated with, endorsed by or connected to LinkedIn.
