The Ultimate Guide to LinkedIn Post Image Sizes: Stop Getting Cropped, Start Driving Engagement

You’ve spent hours drafting the ultimate LinkedIn post. The hook is sharp, the insights are profound, and the call-to-action is dialed in. You attach a graphic, hit publish, and… disaster.

Your brilliant custom graphic is awkwardly cropped at the top and bottom, vital text is cut off, or the image looks fuzzy and pixelated. On a professional network where visual presentation signals credibility, a botched image layout can tank your reach before anyone even reads a word.

Getting your visuals right isn’t just about avoiding a clumsy look—it’s about maximizing digital real estate in the feed. This guide breaks down the exact, up-to-date pixel dimensions for every type of LinkedIn post image, so your content always looks pristine.

Why LinkedIn Image Sizes Actually Matter

LinkedIn is no longer just a digital resume repository; it’s a high-stakes publishing and networking platform. Over 60% of users consume content on mobile devices.

When you use the correct dimensions:

• You control the feed: Taller or square formats take up more physical space on a phone screen, forcing users to pause their scroll.
• You preserve quality: Uploading images at the proper resolution prevents LinkedIn’s automatic compression algorithm from turning your crisp graphics into blurry messes.
• You look professional: Clean, uncropped visuals instantly project authority and attention to detail.

1. Standard Single-Image Posts

When uploading a standard standalone image, you have three primary format options. Your choice depends on your design layout and whether you want to optimize for mobile:

| Format | Recommended Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Portrait (Recommended) | 1080 x 1350 px | 4:5 | Infographics, deep-dive visual cards, and mobile-first content. Maximize screen space. |
| Square | 1080 x 1080 px | 1:1 | Balanced layouts, quote graphics, and clean, universally safe presentations. |
| Landscape | 1200 x 627 px | 1.91:1 | Traditional photos or wide banner-style images. (Note: Takes up less mobile feed space). |

• Max File Size: 5 MB
• Accepted Formats: JPG, PNG, or WebP

Pro Tip: If you want the highest possible engagement on mobile, go with the 1080 x 1350 portrait format. It is the tallest single-image format LinkedIn will display in full without cropping it in the feed.

2. Carousel Posts (Document Shares / PDFs)

Carousels are currently one of the highest-performing content formats on LinkedIn, allowing you to tell a sequential story or break down complex frameworks.
