Preview your LinkedIn post before you publish it
A LinkedIn post holds up to 3,000 characters, per LinkedIn’s help center, but readers only see the opening: the rest waits behind “see more”. Paste your text below to see what falls past the fold, on desktop and on mobile, before you publish.

0 / 3,000 characters
0 word · 0 line · 0 hashtag · 0 mention · 0 link
Paste the text exactly as you will post it. Line breaks are kept, as on LinkedIn. The first line or two carry the post: they are what people see before “see more”.
Preview in the feed
Write or paste your post: the preview updates as you type.
LinkedIn does not publish where it folds a post. The preview cuts after the third line you type, or around 210 characters on desktop and 140 on mobile: an estimate, worth checking against your own feed.
The preview is built in your browser. The text is sent neither to Kasar nor to LinkedIn.
01What LinkedIn’s help center says
LinkedIn’s help center, which we read on October 14, 2026, sets one number for a post: 3,000 characters. Past that, it points you to an article, published on LinkedIn’s publishing platform, which takes up to 125,000. A post goes out to anyone, to your connections only, or to a group.
Post
- Limit
- 3,000 characters
- Use
- The feed: a short text, read while scrolling.
Article
- Limit
- 125,000 characters
- Use
- A long piece, published on LinkedIn’s publishing platform.
What LinkedIn does not publish is where it folds a post in the feed. The preview cuts after the third line you type, or around 210 characters on desktop and 140 on mobile. Treat it as an estimate: compare it with what you see in your own feed, and keep the point in the first line.
02Writing for the fold
Readers decide in two lines. The lines that earn a click state a fact, set up a tension or say what the rest delivers. Line breaks count: an empty line between two sentences uses up one of the three visible lines.
- A warm-up opening : “Today I wanted to share a few thoughts with you…” The fold lands before the idea does.
- Three empty lines to air out the top : they eat the fold and say nothing.
- A fact in the first line : “Three follow-ups out of four go out too late.” The rest explains why.
- Hashtags at the end of the post, where they do not take the hook’s place.
03Fake bold does not read everywhere
The bold and italic you come across in the feed mostly come from “bold text” generators. They swap each letter for a math symbol that looks like it. The Unicode Standard is explicit: these characters are meant for mathematical or technical notation, and should not be used to style ordinary text. The word is no longer made of the same letters: search may not match it, and a screen reader may announce it symbol by symbol. The tool spots them and turns them back into plain letters in one click.
04Mentions are made inside LinkedIn
A mention only exists if you pick the person from the list LinkedIn shows after the @ sign, per its help center. An “@Name” pasted from a text editor stays plain text, and the person is not notified. The tool lists the mentions it finds so you can redo them when you post. LinkedIn also notes that some members turn mentions off.
05After you post, in Kasar
A good post is measured by the conversations it starts. With Kasar, LinkedIn connects through the Chrome extension, which reads the LinkedIn session open in your browser. LinkedIn messages land in the CRM inbox next to email and WhatsApp, and you reply from Kasar.
When someone who read the post writes to you, the extension adds their profile to the CRM in one click: name, job title, company, profile link. The conversation is filed on their record, and an automation can fire when the message comes in to create the callback task.
Frequently asked questions
Up to 3,000, per LinkedIn’s help center as read on October 14, 2026. Past that, LinkedIn suggests writing an article, capped at 125,000 characters. The tool counts characters one by one, accents included, and flags when you go over. A composite emoji, such as a hand with a skin tone, may count as several.
LinkedIn does not publish that threshold. The preview estimates it at three typed lines, or about 210 characters on desktop and 140 on mobile. Put the main idea in the first line: it shows on every screen.
The bold you see in the feed mostly comes from Unicode math symbols, which the standard reserves for mathematical or technical notation. A screen reader may announce them as such, and search may not match the word. To make a point stand out, give the sentence its own line.
No. The preview is built in your browser, with no request to a server, and nothing is stored. The text is sent neither to Kasar nor to LinkedIn.
