Last updated: 20 October 2026. Video figures are from LinkedIn’s own advertising specifications; the other sizes are the values used by the major scheduling and design guides, with any disagreements noted.
The short answer: the standard LinkedIn post image is 1200 × 627 pixels (1.91:1). Square posts work at 1080 × 1080 and portrait posts at 1080 × 1350 (4:5), which takes up the most space in the mobile feed. Use JPG or PNG and keep images under 5 MB. Document carousels use the same square or portrait sizes, and vertical video runs at 1080 × 1920 (9:16).

Which image size should you use?
Portrait (1080 × 1350) is the best default for most posts. Much LinkedIn browsing happens on phones, and a 4:5 image fills more of the screen than a landscape one, which gives your post more room in the feed.
Landscape (1200 × 627) suits link previews, charts and anything designed for desktop. It is also the size LinkedIn uses when it pulls an image from a shared web page.
Square (1080 × 1080) is the safe middle ground when the same image goes to several platforms.
For sharper images, export at twice the size (for example 2160 × 2700 for portrait) as long as the file stays within the size limit.
File types and limits
- Images: JPG or PNG. Guides quote a maximum of 5 MB or 8 MB per image, so stay under 5 MB to be safe. A post can hold several images; the feed shows the first four and a “+” count for the rest.
- Documents: upload a PDF for the most reliable result. Guides quote limits of 100 MB and 300 pages, but 8–12 pages is plenty for a carousel people actually finish.
- Video: MP4 at 30 frames per second. LinkedIn’s video ad specifications allow 75 KB to 500 MB, 3 seconds to 30 minutes, and any ratio from 9:16 to 16:9, with sides between 360 and 1920 pixels. For normal posts, keep videos under 10 minutes; shorter videos tend to be watched to the end more often.
Profile and company page sizes
| Image | Recommended size | Notes |
|---|---|---|
| Profile photo | 400 × 400 px | Square, JPG or PNG |
| Profile background (banner) | 1584 × 396 px | 4:1; keep key content in the centre, as mobile crops the edges |
| Company page logo | 300 × 300 px | Square PNG |
| Company page cover | 1128 × 191 px | JPG or PNG |
Common mistakes
- Text near the edges. Leave a margin around text in banners and carousels, because LinkedIn crops differently on mobile and desktop.
- Uploading a landscape image when portrait would do. On a phone, landscape images take up much less of the screen.
- Mixing sizes in one carousel. Keep every page of a document the same size, or LinkedIn can add bars around the odd ones.
- Heavy PNG files. Photos saved as PNG can easily pass 5 MB; save photos as JPG.
