LinkedIn Post Image Size: What Actually Displays Well

Standalone photo post: 1080 x 1080 pixels

For a single photo attached directly to a post, a square 1080 x 1080 image displays fully in the feed on both desktop and mobile without LinkedIn cropping it further.

Landscape and portrait photos also work well as long as the resolution is high enough — 1080 pixels on the shorter side is a reasonable minimum to keep things sharp, especially since desktop viewers will often see the image larger than mobile users do.

Shared link preview: 1200 x 627 pixels

When you share a link, LinkedIn pulls a preview thumbnail sized around 1200 x 627. If you're creating a custom preview image for an article or landing page, matching this size keeps it from being awkwardly cropped or letterboxed.

This is close to the same ratio used by Facebook's link previews, so one well-sized image can often be reused across platforms rather than creating a separate graphic for each one.

Why LinkedIn images need slightly higher quality

Because LinkedIn is often viewed on larger desktop screens during work hours, a low-resolution image tends to stand out more than it would on a phone-first feed. A photo that looks fine on a small mobile screen can look noticeably soft when the same post is opened on a laptop.

This is one reason it's worth starting from a genuinely high-resolution source rather than reusing a small thumbnail pulled from somewhere else.

It's also worth considering that LinkedIn connections often include colleagues, clients, and recruiters who may view your profile more critically than a casual social audience, which makes a polished, sharp image slightly more important here than on other platforms.

Getting professional-looking results

• Start from a high-resolution original rather than a screenshot or resized copy.
• Keep logos and text away from the outer 10% of the frame in case of platform-specific cropping.
• Compress after resizing to keep upload times fast without visible quality loss.
• If you're posting a carousel or document, keep the same visual style across every slide for a more polished look.

A quick pre-post routine

Before publishing, it's worth previewing how the post looks on both a phone and a desktop browser if you can — the two views crop and scale images slightly differently, and catching an issue before publishing is far less awkward than editing a post after people have already engaged with it.
