LinkedIn image sizes for profiles and posts
LinkedIn Help lists separate sizes for your profile photo, your cover image and images in posts. Drop in your file, and the checker tells you whether it fits each one.
Try it
| Placement | Size |
|---|---|
| Profile photo | 400 x 400 to 7680 x 4320, 8 MB (LinkedIn Help) |
| Cover image | 1584 x 396 |
| Post photo | At least 552 x 276; ratio 3:1 to 4:5; 5 MB |
Through UniPost, a LinkedIn post can take up to 9 images or 1 video. That is UniPost's schedule limit, not a LinkedIn Help figure.
