If there is one metric that matters more than any other on LinkedIn, it is the "dwell time." And the fastest way to increase dwell time is getting people to click "See more."
But how do you know exactly where LinkedIn will cut off your text? Write too much, and your punchline gets hidden. Write too little, and you fail to build curiosity.
In this guide, you will learn exactly how LinkedIn's truncation rules work in 2026, and how to use a LinkedIn hook preview tool to craft the perfect opening.
Why the "See More" Click is Crucial
When a user clicks "See more" to expand your post, the LinkedIn algorithm registers that action as engagement. It signals that your content is interesting enough to stop the scroll.
Posts with high "See more" click-through rates are rewarded with exponentially more reach in the feed. Your hook - the text visible before the cutoff - is effectively your headline.
Exactly Where Does LinkedIn Cut Off Your Post?
LinkedIn's truncation rules are not based strictly on character count. They are based on the number of lines and the presence of media. Here are the rules for 2026:
Text-Only Posts
- Desktop: Truncates after 5 lines or roughly 210-240 characters.
- Mobile: Truncates after 3 lines or roughly 140-160 characters.
Posts with Media (Images/Video/Carousel)
- Desktop: Truncates after 3 lines.
- Mobile: Truncates after 3 lines.
Crucial detail: A line break (pressing Enter) counts as a full line. If you write one sentence, press Enter twice, and write a second sentence, you have already used up three lines on mobile.
How to Preview Your LinkedIn Hook Before Publishing
Because the truncation rules vary depending on line breaks, emojis, and device type, guessing where the "See more" link will appear is risky.
Instead of publishing and immediately editing your post, you can use a free LinkedIn post simulator. Here is how to guarantee your hook works:
- Use the Preview Tool: Type your draft into the LinkedIn Preview tool.
- Toggle Device Views: Switch between desktop and mobile previews to see exactly where the truncation occurs.
- Adjust Your Spacing: If your key curiosity gap is hidden behind the cutoff, remove a line break to pull it up.
- Format Your Text: Add bold or italic text to make the visible portion stand out in the feed.
4 Rules for Optimizing the "See More" Line
Once you know where the cutoff happens, you can strategically write hooks that force readers to expand the post.
1. Build a Curiosity Gap
Your hook should introduce a problem, make a bold claim, or start a story, but withhold the resolution. The answer must be safely hidden below the "See more" line.
Weak: "Here are 5 tips for better time management." (No reason to expand).
Strong: "I wasted 10 hours a week until I changed one simple morning habit:" (Forces the click).
2. End with a Colon or Ellipsis
Visually indicating that a list or explanation is coming is a proven tactic. Ending the visible text with a colon (:) or an ellipsis (...) signals to the brain that the thought is incomplete.
3. Use Whitespace Strategically
Many creators use the "1-1-1 format" (one sentence, blank line, one sentence) to make reading easier. Use a LinkedIn hook preview tool to ensure your blank lines do not push your actual hook out of view.
4. Keep Emojis to a Minimum in the Hook
While emojis can add personality, they take up visual space and character limits. Save them for the body of your post, or use a single, highly relevant emoji at the start of line one.
Stop Guessing, Start Testing
The "See more" click is the gateway to high engagement on LinkedIn. Stop leaving it to chance.
