Key takeaways
- LinkedIn shows post images in full at any ratio from 3:1 to 4:5; outside that range they are centre-cropped.
- Common post sizes are 1200 x 627, 1080 x 1080 and 1080 x 1350, and 4:5 takes the most space in the mobile feed.
- A personal banner is 1584 x 396 (4:1), a Company Page cover 1512 x 256, and an article cover 1920 x 1080.
- Below 1080 pixels wide, images look soft on large screens even when the ratio is right.
- The checker reads the image on your device; nothing is uploaded.
LinkedIn post images display in full at any ratio from 3:1 to 4:5, and the common sizes are 1200 x 627 (1.91:1), 1080 x 1080 and 1080 x 1350; a personal banner is 1584 x 396 and a Company Page cover 1512 x 256. Drop, paste or choose an image in the checker, or type a width and height, and it shows a card for every placement with whether your file fits. The image is read on your device and never uploaded.
How do you use the image size checker?
- Add the image
Drop it, paste it or click to choose a JPG, PNG, WebP or GIF. To test a size without a file, type the width and height in pixels. - Read the cards
You get one card per placement: feed post, carousel page, profile photo, profile banner, Company Page logo, Company Page cover, article cover and event banner. Each card says whether the image fits and what that slot keeps or crops. - Fix what doesn't fit
Download a resized copy made in your browser, or open the LinkedIn image resizer if you want to move the crop yourself.
For post images LinkedIn accepts a whole range, from 3:1 to 4:5, so the checker works out your exact ratio and tests it against that range instead of forcing one fixed size.
What are the LinkedIn image sizes in 2026?
Ratios hold up better than pixel counts, because LinkedIn adjusts display specs whenever its interface changes.
| Where it appears | Size | Good to know |
|---|---|---|
| Feed post image | 1200 x 627 (1.91:1) | Any ratio from 3:1 to 4:5 works; width must exceed 200 px |
| Square or portrait post | 1080 x 1080 / 1080 x 1350 | 4:5 fills the most space in the mobile feed |
| Personal profile banner | 1584 x 396 (4:1) | Widely used, though LinkedIn doesn't publish it; your photo covers the lower left |
| Profile photo | 400 x 400 | Displayed as a circle; a common figure, not an official LinkedIn one |
| Company Page logo | 400 x 400 recommended, 268 x 268 minimum | PNG or JPEG, up to 3 MB |
| Company Page cover | 1512 x 256 | PNG or JPEG, up to 3 MB |
| Article cover | 1920 x 1080 (16:9) | Doubles as the link preview |
| Event banner | 1600 x 900 (16:9) | - |
| Document post (PDF carousel) | Up to 100 MB and 300 pages | Lay pages out at 1080 x 1080 or 1080 x 1350 |
| Any image | Up to 36 megapixels | Maximum resolution |
What does the checker calculate?
It opens the image in your browser and works out its ratio. For feed images the rule is plain arithmetic: between 3:1 and 4:5 the whole picture shows, and outside that range LinkedIn centres it and crops, so whatever sits near the edges is lost.
Staying inside the range prevents cropping, though it doesn't make the image sharp. Below 1080 pixels wide, pictures look soft on large screens.
What happens with a screenshot or a phone photo?
Take two everyday cases. A full-screen desktop screenshot is usually 16:9 (1.78:1), which sits comfortably inside the range. A vertical iPhone photo is 3:4 (0.75), under the 0.8 minimum, so LinkedIn trims its top and bottom; crop it to 4:5 before you post.
Rule of thumb: choose the ratio by how you want the post to look in the feed, then check that the width reaches at least 1080 pixels.
Does image shape change how a post performs?
A 4:5 image stands taller in the feed, so it stays on screen longer while people scroll. A horizontal image leaves more of your text visible above it, and square sits between the two. For more detail, read image sizes for LinkedIn posts and how to change your LinkedIn banner.
The image fits. How do you get the post seen?
Once the image is right, add the post on LinkedInLikes. Members like and comment on it by hand from their own accounts, and it costs nothing.

Frequently asked questions
1200 x 627 (1.91:1) is the usual recommendation, and 1080 x 1080 and 1080 x 1350 also display well. Any ratio between 3:1 and 4:5 shows in full.
A personal profile banner is 1584 x 396, a 4:1 ratio. A Company Page cover is 1512 x 256, as a PNG or JPEG of up to 3 MB.
1920 x 1080, a 16:9 ratio. The same image is used as the link preview when the article is shared.
Only when the ratio falls outside 3:1 to 4:5. In that case LinkedIn centres the image and cuts off the edges.
Usually the resolution is too low: under 1080 px wide, an image looks soft on large screens.
A carousel is a PDF document. Design its pages at 1080 x 1080 or 1080 x 1350, and keep the file under 300 pages and 100 MB.
In the lower left on desktop. Keep important content right of centre and toward the top. The banner maker shows that area while you design.
Yes. 4:5 is inside the supported range, so it isn't cropped, and it takes up the most vertical space in the mobile feed. Use at least 1080 x 1350 so it stays sharp.
