See exactly how your LinkedIn post will look before you publish. Find where the feed cuts your text with "…see more" on mobile and desktop, count your characters, and sharpen your hook to stop the scroll.
Private by design — your draft never leaves this browser.
LinkedIn never shows your whole post in the feed. After a set number of characters or lines, it hides the rest behind a "…see more" link. If your opening lines don't earn the tap, most people scroll straight past and never read your message. This LinkedIn post preview shows your draft rendered like a real feed card on both mobile and desktop, so you can see the exact cutoff and fix it before you hit publish.
The truncation point differs between mobile and desktop. Mobile shows roughly 140 characters or 3 lines, whichever comes first. Desktop shows about 210 characters or 5 lines. These limits cover the text area only — they don't count the author header or any attached media.
| View | Character limit | Line limit | Behavior |
|---|---|---|---|
| Mobile feed | ~140 characters | 3 lines | Shows "…see more" after the cutoff |
| Desktop feed | ~210 characters | 5 lines | Shows "…see more" after the cutoff |
| Max post length | 3,000 characters | — | Hard limit for text posts |
A LinkedIn text post can hold up to 3,000 characters, but only the first 140–210 are visible before the "see more" cutoff. The live character counter above tracks characters, words and lines as you type and warns you as you approach the 3,000-character limit. Posts in the 1,300–2,000 character range tend to earn the most engagement, but front-loading value in your first two lines matters far more than total length.
Your hook is everything that appears before "see more" — your one shot to stop the scroll. Here's what consistently works:
Open with a question to trigger curiosity. Use a power word like "secret", "mistake", "proven" or "framework" to add tension. Include a specific number — data-driven hooks ("I analyzed 500 LinkedIn posts") beat vague ones. Keep the first line between 40 and 80 characters — long enough to intrigue, short enough to read at a glance. And add a line break after your hook; a wall of text gets scrolled past. Avoid starting with "I" — lead with what the reader gains, not with yourself.
LinkedIn supports line breaks, emojis and simple lists, but there is no native bold or italic button. So-called "bold LinkedIn text" is built from Unicode look-alike characters, which screen readers often can't read aloud and search can't index — use it sparingly. This preview renders plain text with your line breaks exactly the way LinkedIn does, so what you see is what your audience gets.
On mobile, LinkedIn truncates at approximately 140 characters or 3 lines, whichever comes first. On desktop, the cutoff is around 210 characters or 5 lines. This tool shows you both truncation points in real time as you type.
LinkedIn text posts have a 3,000 character limit. However, only the first 140–210 characters are visible in the feed — the rest is hidden behind "see more". That's why your opening hook matters more than total length.
LinkedIn supports line breaks, emojis and lists, but has no built-in bold or italic. "Bold" text uses Unicode look-alike characters that hurt accessibility and search visibility. Line breaks and emojis are the safest way to format a post.
Paste your draft into the editor above. You'll instantly see mobile and desktop feed previews with the exact "see more" cutoff, a live character counter, and a hook score — so you can edit before you publish.
Keep your first line between 40 and 80 characters — long enough to spark curiosity but short enough to read at a glance before the "see more" cutoff. The preview above shows exactly what fits above the fold on mobile and desktop.
Three to five relevant hashtags is the sweet spot. More than that looks spammy and can suppress reach. Place them at the end of the post so they don't interrupt your hook.
Press Enter to add a line break while composing. Short paragraphs and white space make a post far easier to read in the feed, and this preview keeps every line break exactly where you put it.
A strong hook opens with a question, a specific number, or a bold claim, avoids starting with "I", and leads with what the reader gains. The hook score above rates your opening and gives tips so more people tap "see more".
