LinkedIn image size for link previews, posts and pages

What size should the LinkedIn link preview image be?

The image that appears when someone pastes your URL into a post comes from your page's og:image tag. LinkedIn's help article on making your website shareable lists three requirements for the sharing module: a maximum file size of 5 MB, minimum dimensions of 1200 pixels wide by 627 pixels high, and a recommended ratio of 1.91:1.

The same article adds one display rule: images less than 401 pixels wide display as a thumbnail rather than a full width card. So the minimum is not a soft suggestion. Below it you get a different, smaller layout.

If you already make a 1200 by 630 share image for other networks, it clears LinkedIn's minimum and sits at almost exactly 1.91:1, so one file serves both. How to crop it and where to keep text safe is in our 1200 by 630 crop guide; this page does not repeat it. Everything else about previews lives under the Open Graph section.

LinkedIn image sizes at a glance

Only sizes that a LinkedIn Help page states are listed. Where LinkedIn gives a minimum and a recommended size, both are shown. Where it gives neither, the row says so instead of guessing.

Why are there two thumbnail thresholds?

Because two LinkedIn Help articles give two numbers. The shareable website article says images under 401 pixels wide display as a thumbnail. The LinkedIn Pages image specifications say a custom image on a page post with a URL must be more than 200 pixels wide, and below that it appears as a thumbnail on the left of the post.

The articles cover slightly different cases: the first is the preview LinkedIn builds from your tags, the second is an image a Page admin attaches by hand to a link post. You do not need to work out which rule wins. At 1200 pixels wide your image is far above both.

What about image posts that are not link previews?

LinkedIn Help does not publish a single recommended size for an ordinary photo post from a member profile in the articles we checked in November 2026. Two things it does say are useful.

• The Pages image article says that when you post an image only, or an image and text, the image is enlarged to fit the feed, and that the 200 pixel thumbnail rule does not apply.
• The same article says images on mobile will not be cropped, and images of other ratios appear in full size with subtle white padding.
• For ads, the shareable website article lists the single image ad specification in full: landscape 1.91:1, square 1:1 and vertical 1:1.91, each with its own minimum and maximum, and it warns that square and vertical images might be cropped when ads are shared organically.

If you want one safe default for feed images, the 1.91:1 landscape shape is the only one that appears in both the link preview rules and the ad rules.

Company page and profile images

These are not link previews, but people search for them under the same phrase, so here is what LinkedIn says. All LinkedIn Page images must be PNG or JPEG files with a maximum size of 3 MB. LinkedIn recommends a high resolution JPEG over a PNG for the best result, warns that the cover image may be trimmed horizontally or vertically to fit the screen, and asks you to keep key details away from the edges, especially the lower right corner.

The logo is shown on both light and dark backgrounds, and a transparent logo is placed on white. Test it on both before you upload.

For a member profile, LinkedIn's article on adding a profile cover image asks for a JPG or PNG file under 8 MB at a recommended 1584 by 396 pixels. It notes that how the image appears can change with browser window size and screen resolution, and that a LinkedIn Live broadcast temporarily replaces the cover while the stream runs.

Set and check your link preview image

1. 01

   Make the file

   Export a 1200 by 630 JPEG under 5 MB. Give it a new filename every time you change it, so no cache can serve the old file at the same address.

2. 02

   Point og:image at it

   In WordPress, set it as the post's social image in your SEO plugin, or as the featured image if your tags use that. Setup is in the WordPress Open Graph setup guide.

3. 03

   Purge your cache

   Clear the page cache and any CDN copy for the post, then view source logged out and confirm one og:image with an absolute https URL.

4. 04

   Open the Post Inspector

   Go to https://www.linkedin.com/post-inspector/, paste the post URL into the field and click Inspect.

5. 05

   Confirm the preview

   Check that the preview shows your new image at full width, not as a small thumbnail. The walkthrough of every field is in using the LinkedIn Post Inspector.

Inspecting also refreshes LinkedIn's stored copy, but LinkedIn's refresh article says the change applies only to new posts. Existing posts keep the image they were published with. To test markup before the page is public, paste the source into our in-browser link preview checker, which fetches nothing.

What goes wrong

• An image just under the minimum. A 1200 by 600 banner misses the 627 pixel height LinkedIn asks for. Export at 1200 by 630 or larger.
• A file over 5 MB. Large PNG screenshots exceed the limit easily. Use JPEG for photographs and compress before upload.
• A square image as the og:image. It is not the 1.91:1 ratio LinkedIn recommends for previews, so the card will not look as intended.
• Text near the edges of a page cover. LinkedIn says covers may be trimmed on different screens and asks for key details in the center, away from the lower right corner.
• A transparent logo with dark lettering. LinkedIn shows transparent logos on white and also on dark backgrounds, so check contrast on both.
• Changing the image and expecting old posts to follow. The refresh affects new posts only; see wrong image and stale text fixes for the same pattern on Facebook.

Check the LinkedIn image size is right

• The og:image file opens in a private window, over https, and reports at least 1200 by 627 pixels.
• The file size is under 5 MB for the link preview and under 3 MB for Page images.
• The Post Inspector shows a full width image, not a thumbnail, for your URL.
• Your Page cover keeps its key text inside the center when you view the Page on a phone and on a desktop.
• Your profile cover is 1584 by 396 and under 8 MB before you upload it.
