LinkedIn’s feed sits in a narrower column than most social platforms, especially on desktop, which changes how much of an image actually shows before someone has to click through. Build for the wrong ratio and your image gets letterboxed or cropped in a way that hides the point of the post.
Here are the dimensions LinkedIn uses.
| Type | Size | Aspect ratio |
|---|---|---|
| Profile Photo | 400 x 400 | 1:1 |
| Background / Cover | 1584 x 396 | 4:1 |
| Post Image (Landscape) | 1200 x 627 | 1.91:1 |
| Post Image (Square) | 1080 x 1080 | 1:1 |
| Post Image (Portrait) | 1080 x 1350 | 4:5 |
| Company Logo | 300 x 300 | 1:1 |
| Company Cover | 1128 x 191 | 5.9:1 |
| Article Cover | 1200 x 644 | 1.86:1 |
| Ad (Sponsored Content) | 1200 x 627 | 1.91:1 |
Which size to actually use
For a regular post, portrait at 1080 x 1350 takes up more vertical space in LinkedIn’s feed than a square or landscape image, so it’s worth defaulting to if you want the post to hold attention while scrolling. Square at 1080 x 1080 is a safe fallback when the image itself doesn’t crop well as a portrait.
If you’re sharing a link, LinkedIn pulls a 1200 x 627 preview card, that’s also the size to use for sponsored content, since the ad format shares the same dimension.
Background and company cover images are wide, low-height banners, 4:1 and 5.9:1 respectively. Keep any text centered rather than near the left or right edges, both get clipped differently depending on the viewer’s screen width.
Format and common mistakes
Export at the target size instead of uploading something oversized and letting LinkedIn scale it down, you keep more control over cropping. A social media image resizer makes quick work of this if you’re starting from a photo shot at a different ratio.
A common mistake on LinkedIn specifically is treating the background cover like a Facebook or Twitter banner and centering the important content, then having it clipped because LinkedIn’s crop behaves differently across desktop and mobile. Check your layout against the social media image size guide before publishing if you’re not sure how it’ll render.
Article covers and post images with a lot of text or fine detail also benefit from checking file size before upload. An image compressor keeps quality intact while shrinking the file, which matters if you’re publishing frequently through BulkPublish or scheduling in bulk.
