See where your post gets cut by "see more"
Feeds show only the first few lines of a post. Paste yours to see roughly what people read before they decide to tap "see more", on LinkedIn, Instagram and Facebook, on a phone or a desktop.
Approximate: networks do not publish where they fold, and it varies with screen, font and app version.
How to use the post preview
- 1
Paste your post into the box. The preview updates as you type; nothing is sent anywhere.
- 2
Choose a network (LinkedIn, Instagram or Facebook) and a device (mobile or desktop).
- 3
Read what is visible before "see more". That is your hook: it has to make people want the rest.
- 4
Rewrite the opening until the visible part stands on its own, then check the other device.
Example
A story post, cut where LinkedIn on a phone would roughly fold it.
Input
I almost turned down the best client we have ever had. Their first email was three lines long and asked for a discount before saying hello. I drafted a polite no. Then I called instead. Ten minutes later I understood the real problem: they had been burned by two agencies and wanted to test us before trusting us. We agreed on a small paid pilot. Two years on, they are our biggest account. Lesson: a rough first message is often a signal of past pain, not bad manners.
Result
I almost turned down the best client we have ever had. …see more
LinkedIn on a phone shows ~54 / 473 characters.
Why the fold matters more than the limit
LinkedIn allows 3,000 characters and Instagram 2,200, but in the feed people see a few lines and a "see more" link. Everything after the fold is only read by people who chose to open the post. So the real job of the first lines is not to start the story, it is to earn the click.
Line breaks matter as much as length. A blank line takes a full line of the preview, so a post that opens with a one-line hook, a blank line and a second line may show less text than one long sentence, but it often reads better. The preview shows both effects.
This is an approximation, and here is why
No network publishes exactly where it folds a post. The cut depends on screen width, font size, the app version, whether there is an image, and even the language. The tool uses typical values: about three lines on LinkedIn, two on Instagram and around five on Facebook, with fewer characters per line on a phone. Use it to check that your hook lands early, not to count to the exact character.
Tips for a strong first fold
- Say the most interesting thing first. Context can wait until after "see more".
- Check the mobile view: most people scroll feeds on a phone, where fewer characters fit.
- Avoid starting with a greeting or "I am excited to announce". It uses your visible lines for nothing.
- A question, a number or a surprising result in the first line gives people a reason to open the post.
- If you use an emoji, put it after the hook, not before: it takes space and adds little.

How many characters show before "see more" on LinkedIn?
LinkedIn does not publish a number. In practice it is around two to three lines, often quoted as roughly 200 characters on desktop and fewer on a phone. Line breaks shorten it further.
Where does Instagram cut a caption?
Instagram shows about one to two lines of a caption in the feed, commonly around 125 characters, before "more". Put the key message and any call to action up front.
Is the preview exact?
No, and no outside tool can be. The fold moves with screen size, font, images and app version. The preview uses typical values so you can check your hook is early enough.
Do line breaks change where the post is cut?
Yes. Each line break, including blank lines, uses one of the few visible lines, so a post with many short lines folds after fewer characters.
Why compare mobile and desktop?
Phones fit fewer characters per line, so the same post shows less on mobile. Since most feed reading happens on phones, the mobile view is the one to optimise for.
Is my text stored?
No. The preview runs in your browser and nothing you paste is sent anywhere.
