I rewrote the first line of one post 11 times last week. The post itself took 10 minutes. The opening took an hour. Worth it: on LinkedIn, people decide in the first three lines whether to tap "more". If the hook sits below the cut, almost nobody sees it. What worked best: → A number in the first line → No greeting, no context → One short sentence per line
LinkedIn and Instagram cut by lines, so the cut moves with screen width. X counts like X does: links as 23, emoji as 2.
Schedule it with FeedHiveLinkedIn shows the first three lines of a post in the feed and puts "…more" (often called "see more") at the end of the third line. It cuts by lines, not by a fixed number of characters.
With no line breaks, three lines hold about 140–160 characters on a phone and 210–250 on desktop. Every line break starts a new line, so a post that opens with three short lines shows only those three lines, however short they are.
The LinkedIn character limit is 3,000 for a post and 220 for your headline, according to LinkedIn Help. The counter under the preview counts every character, including spaces, line breaks and emoji.
| Where | Limit |
|---|---|
| Post | 3,000 characters |
| Shown before "…more" | 3 lines (about 140–160 characters on a phone, 210–250 on desktop) |
| Headline | 220 characters |
Feeds show the start of a post and hide the rest behind a "more" link. Most people decide whether to tap it from the lines they can already see, so a strong opening does most of the work.
LinkedIn and Instagram cut by lines, not by a fixed number of characters. A line break uses up a whole line, so a post that opens with three short lines can lose its third sentence below the cut. That's why the cut lands in a different place on a phone and on a desktop, and why it helps to check it before you post.
Lead with the result
Put the outcome, number or claim in the first line, and the setup after it.
Cut the warm-up
Greetings and "I've been thinking about…" use the lines people actually see.
Watch your line breaks
Each empty line costs a full line above the cut. Use them after the hook, not before it.

Switch between Phone and Desktop. Most people read on a phone, where the cut comes earlier.
Paste your post into the LinkedIn post preview tool above to see your name, headline, text and image as they'll appear, including the "…more" cut on a phone and on desktop.
LinkedIn shows three lines. Without line breaks that's about 140–160 characters on a phone and 210–250 on desktop. Line breaks and emoji change it, which is why it's worth checking each post.
3,000 characters per post, including spaces and line breaks. The counter under the preview shows how many you've used.

The cut is measured, not guessed: the tool lays out your text at the same text size and width as the feed and finds where the last visible line ends. Apps differ slightly between devices, font settings and app versions, so treat the cut as a close guide and leave a few words of room.
No. The preview, the character count and the PNG download all run in your browser. FeedHive never receives or stores your text, profile photo or post image.
