LinkedIn Image Sizes: Prepare Posts That Survive the Feed

TL;DR

• Prepare a LinkedIn image for its actual use: a photo post, a document slide and a link preview are different assets.
• Use a readable composition with a clear focal point, and verify the current upload requirements before publishing.
• Keep the source file editable so you can fix crops or small text before the post goes live.
• Inspect both the full image and the smaller feed presentation rather than judging the design only at full desktop size.

A useful LinkedIn image starts with one message

The right LinkedIn image size helps a visual survive upload and cropping, but the design still needs a clear job. A chart should support a conclusion. A photograph should make the subject recognizable. A document cover should tell the reader why opening the sequence is worthwhile.

Start by writing the image's message in one sentence. If the sentence contains three unrelated lessons, the visual probably needs to become several slides or separate posts. A larger canvas does not solve an overloaded idea.

Separate photo posts from link previews

LinkedIn's photo-sharing documentation currently describes a 5 MB photo limit, a minimum of 552 × 276 pixels, a recommended width of 1080 pixels and aspect ratios from 3:1 to 4:5. It also explains that oversized ratios can be cropped and uploaded photos cannot be edited or resized after posting. Recheck that page when preparing a new workflow because platform requirements can change.

As working canvases, a 1080-pixel square or a 1080 × 1350 portrait gives a designer a straightforward starting point for a photo post. These are production choices within the documented range, not a claim that one ratio always receives more reach.

A shared URL has a different source of imagery: the website's preview metadata. Replacing the photo in your design folder does not necessarily update a link preview that points to a website. If the wrong preview appears, inspect the destination page and its social metadata rather than endlessly re-exporting an unrelated upload.

Make the visual readable in a moving feed

Imagine the post on a small screen between two other updates. The central idea should remain visible without requiring the reader to magnify the image. Use fewer labels, meaningful contrast and enough space around the focal point.

For an illustrative chart about support tickets, show the few categories that support the argument. Put methodology, date range and a fuller explanation in the post or linked article. Do not present a cropped chart that removes the axis or changes the apparent relationship between values.

For a screenshot, crop to the relevant control or result and remove private customer information before exporting. If the screenshot still needs a paragraph of tiny annotation, use a separate explanatory slide. Keep examples clearly labeled when the data is hypothetical.

Prepare a consistent multi-image sequence

A multi-image post should have an intentional order. Start with the overview, continue through the evidence and finish with the next step. Keep margins and typography consistent so readers can concentrate on the explanation.

Do not assume the feed will lay out every multi-image combination identically. Preview the sequence and make sure the first image works as the opening visual. Save a contact sheet locally if it helps the reviewer check that no slide is duplicated or missing.

If you need a page-by-page teaching format, consider a document post and follow the document-carousel planning guide. A collection of photos and an uploaded document are different publishing formats; choose the one the connected publishing workflow actually supports.

Use an export and review handoff

A reviewer should receive the final caption, the intended account, the export files and the publication context. An isolated image file cannot show whether the caption contradicts the chart or links to an outdated landing page.

Store a new revision when a visual changes. A simple filename such as onboarding-chart-linkedin-v04.png is more reliable than several files all called final.png.

Schedule only after seeing the finished post

Use PostCoPilot to prepare the draft and schedule supported LinkedIn posts once the visual and caption have been reviewed together. Verify the connected profile or page, local publication time and destination link. Keep the editable source so a future update can correct the visual without recreating the entire campaign.

For the writing that accompanies the image, use the LinkedIn formatting guide. A clear image and a well-structured caption should reinforce the same point.
