LinkedIn Post Preview Best Practices

Keep these practices in mind while drafting your next LinkedIn post.

Keep Your Hook Short and Self-Contained

Your hook should land in one sentence or two at most. It needs to be short enough to display fully before the "See more" cut and specific enough that skimming readers immediately understand what they're getting if they click through.

Check Mobile Every Time

More than 57% of LinkedIn traffic comes from mobile. A post with careful formatting on desktop can look like a wall of text on a phone if your paragraphs are too long. MagicPost's previewer makes this check instant; there's no reason to skip it.

Use Correct Image Dimensions

LinkedIn recommends 1200 x 627 px for link post images and 1080 x 1080 px for square post images. Portrait images (1080 x 1350 px) tend to take up more feed real estate and perform well on mobile.

Check your image in the preview before publishing. If it's cropping unexpectedly, resize it before you go live.

Read It Out Loud Before Publishing

This isn't about the preview tool; it's about the content. Reading your post aloud before previewing it catches awkward phrasing, run-on sentences, and rhythm issues that spellcheck misses. Do this before you even open the previewer.

If your post uses LinkedIn text formatting (bold, italics, or special characters), check that those render correctly in the preview too. Unicode formatting occasionally displays inconsistently depending on the device and LinkedIn client version.
