What Size Should a LinkedIn Post Image Be?

When you create or schedule LinkedIn posts, you’ll have the option to use several different post types, each with their own ideal image sizes that will ensure a clear, professional final result.

Here’s a look at the ideal LinkedIn image post size for different post types available on the platform.

LinkedIn Image Post Size

LinkedIn image posts can be one of three orientations: square, landscape, or portrait.

The ideal image dimensions for these kinds of posts are as follows:

Square: 1080 x 1080 pixels
Landscape: 1200 x 627 pixels
isPortrait: 627 x 1200 pixels

Note that each of these image types is best used for different applications as part of your organic LinkedIn marketing. For example, landscape images tend to be more effective for visual storytelling, while portrait images tend to be better suited to infographics and text-heavy visuals.

Making sure you match your content to LinkedIn image parameters is important for maximizing effectiveness when you’re trying to strategize content variance and how often you should post on LinkedIn.

LinkedIn Article Image Sizes

The article images prefacing LinkedIn articles are important for grabbing your audience’s attention, stopping the scroll, and maximizing click-through to the articles themselves.

When posting an article to LinkedIn, you’ll be prompted to attach a feature image, which is the image that will appear in your audience’s LinkedIn feed, and a banner image, which will appear at the top of the article itself.

The ideal LinkedIn post image sizes for these slots are:

Feature image: 1200 x 644 pixels
Banner image: 600 x 322 pixels

Write and schedule content for LinkedIn with Typefully.

LinkedIn Linked Post Image Size

Linked posts are used to share content hosted somewhere other than the LinkedIn platform (e.g. blog posts, infographics, whitepapers, and other content hosted on your own website.)

The ideal size for a linked post image size is 1200 x 627 pixels.

Note that when you add an outgoing link to a linked post, LinkedIn will automatically generate a thumbnail grabbed from the target content, which you may find is ideal for your purposes. However, you’ll always have the option to customize the preview image by clicking on the “Edit” icon when drafting your content.

LinkedIn Sponsored Posts Image Size

Aside from organic LinkedIn content, you’ll also need to set the correct LinkedIn post image size for any sponsored content, and ensure your brand’s content looks great across all touchpoints.

If you’ve ever wondered ‘what size image for LinkedIn posts’ in a paid context, here are the ideal image sizes for different types of sponsored content:

Single image ads: 1200 x 627 pixels
Carousel ads: 1080 x 1080 pixels

LinkedIn Videos

The thumbnails for LinkedIn videos don’t have specific pixel dimensions. However, you can still make sure they look great across different devices and contexts by sticking to specific ratios.

Here are the best image ratios for LinkedIn videos:

Vertical: 4:5 or 9:16
Landscape: 16:9
Square: 1:1
