The Ultimate Guide to LinkedIn Post Image Sizes in 2026
Visuals are no longer optional on LinkedIn—they are essential for cutting through the noise of a crowded feed. Whether you are sharing a company update, publishing a thought-leadership article, or launching a targeted carousel, using the correct dimensions ensures your content looks professional, crisp, and fully optimized across both desktop and mobile devices.
This guide breaks down the exact image sizes you need for every type of LinkedIn post.
Why LinkedIn Image Sizes Matter
When an image is uploaded with incorrect dimensions, LinkedIn’s algorithm automatically crops or stretches it. This often leads to awkward framing, pixelation, or important text getting cut off on mobile screens.
By adhering to native aspect ratios, you maximize screen real estate, improve readability, and signal a high level of brand professionalism.

Deep Dive: Choosing the Right Format for Your Goal
1. The Vertical Post ($1080 times 1350$ px)
If your primary goal is stopping the scroll, vertical imagery is your best friend. By utilizing a 4:5 aspect ratio, vertical posts take up significantly more vertical space on mobile feeds than square or horizontal images. This makes them ideal for infographics, step-by-step frameworks, and data-heavy visuals.
2. The Square Post ($1080 times 1080$ px)
Square posts offer a balanced, symmetrical look that works reliably across all devices. They are the standard choice for multi-image posts or when you want a clean, modern aesthetic that feels equally at home on LinkedIn as it does on Instagram or Facebook.
3. Standard Shared Images ($1200 times 627$ px)
When you share a URL link, LinkedIn automatically generates a preview card using a horizontal landscape image. Designing custom graphics in this size ensures your external link previews look intentional and polished rather than pulling a random, poorly cropped thumbnail from your website.
4. Document / Carousel Posts
LinkedIn document posts (often referred to as carousels) allow users to swipe through multiple pages of content.
- Recommended Dimensions: $1080 times 1080$ px (Square) or $1080 times 1350$ px (Vertical).
- File Format: PDF files exported directly into LinkedIn. Vertical carousels perform exceptionally well because they dominate the mobile screen as users swipe horizontally.
Best Practices for LinkedIn Visuals
- Design for Mobile First: Over 60% of LinkedIn traffic originates from mobile devices. Always preview your graphics on a smaller screen to ensure text is legible without zooming in.
- Watch the Safe Zones: Keep crucial text and logos away from the very edges of your canvas to prevent accidental cropping.
- Mind Your File Size and Type: Stick to PNG or high-quality JPEG formats. Ensure file sizes stay well within LinkedIn’s limits (typically up to 5MB for standard images) to avoid upload errors or compression artifacts.
By keeping these dimensions handy in your design workflow, you can ensure your content always puts its best foot forward.
