The Ultimate Guide to LinkedIn Post Image Sizes: Stop Your Visuals from Getting Cropped

We’ve all been there: you spend hours crafting the perfect graphic, tweaking every font and color, only to hit “Post” on LinkedIn and watch your masterpiece get aggressively cropped, chopped, or awkwardly pixelated.

On a professional network where first impressions matter instantly, a poorly scaled image can kill your engagement before anyone even reads your headline. Because the majority of professionals browse LinkedIn on mobile devices, understanding how the platform handles visual assets is critical.

If you want your content to stand out, look sharp, and stop the scroll, here is your definitive, up-to-date cheat sheet for LinkedIn post image sizes.

1. Standard Feed Post Image Sizes

When posting a single image to your feed, you have three primary orientation options. Choosing the right one depends entirely on the type of story you are trying to tell.

• Portrait (Recommended for Engagement): 1080 x 1350 pixels (4:5 Aspect Ratio)
  • Why use it: Portrait is the ultimate format for mobile-first content. Because mobile screens are vertical, a 4:5 image takes up the maximum allowable vertical real estate in the LinkedIn feed without forcing the user to tap to expand. More screen space equals longer dwell time, which translates directly into higher engagement.
• Square (The Safe All-Rounder): 1080 x 1080 pixels (1:1 Aspect Ratio)
  • Why use it: If you are repurposing graphics from Instagram or cross-posting to other platforms, square is your best friend. It displays predictably and cleanly across both desktop and mobile devices. It’s ideal for quote cards, clean product shots, and data charts.
• Landscape (Best for External Links): 1200 x 627 pixels (1.91:1 Aspect Ratio)
  • Why use it: Landscape is LinkedIn’s traditional landscape layout. While it doesn’t command as much feed space on mobile, it is the essential format when sharing link previews (where LinkedIn automatically pulls the preview image from your website’s Open Graph data) or showcasing panoramic photography.

2. Carousels and Document Posts (PDFs)

Document shares and carousels are engagement powerhouses on LinkedIn. Whether you are dropping a multi-slide educational guide or a mini-portfolio, getting the slide dimensions right is vital.

• Square Slides: 1080 x 1080 pixels (1:1 ratio)
• Portrait Slides: 1080 x 1350 pixels (4:5 ratio)
• File Format: Export your slides as a high-quality PDF before uploading.
• Pro-Tip: Stick to a 1080 x 1350 px portrait layout for documents whenever possible. It forces readers to slow down and swipe through, increasing interaction signals that the algorithm loves.

3. Profile and Company Page Assets

Your personal profile or company page is your digital storefront. If your banner or profile picture looks blurry, it undermines your professional credibility.

• Personal Profile Picture: 400 x 400 pixels (1:1 ratio). Remember that LinkedIn crops profile photos into a circle, so keep your face or logo centered and leave breathing room around the edges.
• Personal Background / Cover Banner: 1584 x 396 pixels (4:1 ratio). Keep in mind that mobile screens crop the sides of personal banners aggressively, and your profile picture overlaps the bottom-left corner. Keep your vital text and branding toward the center-right.
• Company Page Logo: 400 x 400 pixels.
• Company Page Cover Photo: 1128 x 191 pixels.

4. Technical Constraints to Keep in Mind

Designing to the right pixel dimensions is only half the battle. To ensure your upload succeeds without getting compressed into a pixelated mess, pay attention to these technical rules:

1. Maximum File Size: For standard feed images, keep your files under 5MB. Document/carousel PDFs can go up to 100MB.
2. File Formats: Stick to PNG for graphics containing text, charts, or sharp logos to prevent color bleeding and artifacts. Use JPEG/JPG for photographic imagery to keep file sizes optimized. WebP is also widely supported for feed updates.
3. Resolution Quality: Always design at higher resolutions matching the exact aspect ratio (
