LinkedIn Post Image Sizes: Ultimate Guide

When it comes to building your personal brand or driving professional engagement, LinkedIn is the premier stage. Yet, nothing kills a brilliant post faster than a blurry, awkwardly cropped, or pixelated image.

Understanding the right LinkedIn post image size is essential to keeping your content looking sharp, professional, and optimized for both desktop and mobile feeds.

The Essential LinkedIn Post Image Sizes

LinkedIn supports a variety of layouts depending on what kind of story you want to tell. Here is the ultimate breakdown of the most popular dimensions:

1. Square Posts (Best for General Updates & Carousels)

• Recommended Dimensions: 1080 x 1080 pixels (or 1200 x 1200 pixels)
• Aspect Ratio: 1:1
• Why use it: Square images are versatile and take up a healthy amount of vertical real estate on mobile screens without getting cut off. They are the gold standard for PDF document carousels and multi-image posts.

2. Portrait / Vertical Posts (Best for Maximum Feed Presence)

• Recommended Dimensions: 1080 x 1350 pixels (or 627 x 1200 pixels)
• Aspect Ratio: 4:5 (or vertical equivalent)
• Why use it: Because most professionals scroll LinkedIn on their phones, vertical posts dominate mobile screens, forcing users to pause their scroll. If you want maximum visibility, portrait orientation is your best friend.

3. Landscape / Horizontal Posts (Best for Photographs & Infographics)

• Recommended Dimensions: 1200 x 627 pixels
• Aspect Ratio: 1.91:1
• Why use it: Traditional landscape shots work well for landscape photography or screenshots. However, keep in mind that they take up less vertical space on mobile feeds.

4. Shared Link Preview Images (Open Graph Images)

• Recommended Dimensions: 1200 x 627 pixels
• Why use it: When you drop an external blog link or website into a post, LinkedIn automatically pulls a preview thumbnail. Designing your web page’s Open Graph image to these precise dimensions ensures your link preview doesn’t render with awkward cropping.

Pro-Tips for Perfect LinkedIn Visuals

• Watch the Safe Zones: Keep vital text and graphic elements centered. Avoid placing crucial details right on the outer edges where mobile apps might clip them.
• Stick to Clean Formats: Upload your images as high-resolution PNG or JPEG files to prevent compression artifacts.
• Mind File Size Limits: LinkedIn allows images up to 5MB, so ensure your graphics are crisp without being overly bloated.
