Using the right LinkedIn image size is critical for grabbing attention in the feed. Upload the wrong dimensions, and LinkedIn will crop your visual awkwardly, making your post look unprofessional and hurting your engagement.
To stop the scroll, your images need to be sharp, perfectly scaled, and optimized for both mobile and desktop screens. Whether you are sharing a standard photo, a carousel, or updating your profile banner, this guide covers the best image sizes for LinkedIn in 2026.
Best Image Size for LinkedIn Posts
When you attach an image directly to a post, LinkedIn gives you a few options. The dimensions you choose dictate how much screen real estate your post commands.
Here are the ideal dimensions for standard image posts:
- Portrait (Vertical): 1080 x 1350 pixels (4:5 ratio). This is the best image size for LinkedIn posts because it takes up the maximum vertical space on mobile devices.
- Square: 1080 x 1080 pixels (1:1 ratio). A safe, standard format that looks great on both mobile and desktop.
- Landscape (Horizontal): 1200 x 627 pixels (1.91:1 ratio). Use this if you are sharing wide photography, though it commands less vertical space in the feed.
Always keep your file size under 5MB. LinkedIn compresses images, so starting with a high-resolution file prevents pixelation.
LinkedIn Carousel Dimensions
Carousels (PDF documents) are one of the highest-converting formats on LinkedIn. Because they require users to swipe or click through, they generate high engagement signals.
The optimal dimensions for LinkedIn carousel pages are:
- Square (Recommended): 1080 x 1080 pixels. Square carousels render perfectly on all devices and are easiest to read.
- Vertical: 1080 x 1350 pixels. If you want maximum screen coverage, vertical pages work incredibly well.
Make sure you export your final carousel as a single PDF document before uploading it to LinkedIn.

LinkedIn Link Preview Image Size
When you paste a URL into a LinkedIn post, the platform automatically generates a link preview card with an image pulled from that website.
- Link Preview Image Size: 1200 x 627 pixels (1.91:1 ratio).
If the image on the destination site is smaller than this, LinkedIn will display a tiny square thumbnail on the left side of the text, which severely reduces your click-through rate.

LinkedIn Profile Image & Banner Sizes
Your personal profile is your digital business card. The visual elements at the top of your profile are the first thing people see when they click your name.
Personal Profile Photo
- Size: 400 x 400 pixels (minimum).
- Ratio: 1:1 (Square, but rendered as a circle).
- Tip: Make sure your face takes up at least 60 percent of the frame.
LinkedIn Background Banner Size
- Size: 1584 x 396 pixels.
- Ratio: 4:1.
- Tip: Keep important text or logos near the top right of your banner. The bottom left corner will be obscured by your profile photo on desktop, and the layout shifts entirely on mobile.

Frequently Asked Questions
Why does my LinkedIn image look blurry?
LinkedIn automatically compresses uploaded images to save bandwidth. To avoid blurriness, always upload PNG files instead of JPEGs and ensure your starting resolution is exactly 1080 pixels wide or higher.
Can I post multiple images on LinkedIn?
Yes, you can upload up to 9 images in a single post. LinkedIn will automatically arrange them into a grid layout. If you upload two images, they will be placed side by side. For three or more, the grid adapts dynamically.
What is the maximum file size for LinkedIn images?
LinkedIn supports a maximum file size of 5MB for profile photos and up to 8MB for images attached to posts.
Conclusion
Using the correct LinkedIn image size is the foundation of a professional presence. Stick to 1080 x 1350 for maximum mobile visibility, 1080 x 1080 for carousels, and 1200 x 627 for link previews. Once your images are perfectly sized, focus on writing a strong caption to match.
