LinkedIn Post Preview
Write your post, drop in an image and see the LinkedIn feed version on the right. The feed shows your name, headline and time, then about 210 characters and a "more" link. An image renders at 1.91:1 or 4:5, reactions show as a stack of icons with a count, and the Like, Comment, Repost and Send bar sits below. Toggle dark mode and desktop to check both, then schedule it when it looks right.

The card follows LinkedIn's current layout, including where "more" cuts the text. Real feeds vary slightly by device and app version.
What the LinkedIn feed does to your post
The feed shows your name, headline and time, then about 210 characters and a "more" link. An image renders at 1.91:1 or 4:5, reactions show as a stack of icons with a count, and the Like, Comment, Repost and Send bar sits below.
Under 12 words in the first line, one idea per post, short lines with white space. Posts that ask a real question get comments, and comments are what the LinkedIn feed rewards.
How to use the preview
- Enter your name and headline and paste your post.
- Add an image or your profile photo: both stay in your browser.
- Switch between light and dark and between mobile and desktop widths.
- Click "more" on the preview to see the expanded version, then copy the text or send it to the scheduler.
Why preview before posting
Most engagement decisions happen before the fold. If the first line is a half-sentence or the image crops off a face, the post underperforms and there is no edit that fixes it after the first hour. Previewing is a ten-second check that catches both. Social by InstantDM shows the same preview for all eight platforms side by side inside the composer.
