The Ultimate Guide to LinkedIn Post Image Sizes in 2026
When you scroll through your LinkedIn feed, what makes you stop? Is it a wall of dense text, or is it a striking, professionally formatted visual that catches your eye?
Images are one of the most powerful tools in your LinkedIn content strategy. Posts with images consistently generate higher engagement, more comments, and broader reach. However, there is nothing quite as frustrating as crafting a brilliant post, attaching a carefully designed graphic, and watching LinkedIn awkwardly crop out your text, cut off your headline, or turn a crisp image into a blurry pixelated mess.
To ensure your visual content always looks sharp and professional, here is your complete, up-to-date guide to LinkedIn post image sizes and best practices.
Why LinkedIn Image Dimensions Matter
LinkedIn’s algorithm and display layout are designed to optimize the user experience across desktop and mobile devices. When you upload an image that doesn’t fit standard aspect ratios, LinkedIn’s auto-crop tool takes over—and it rarely guesses correctly.
Using the right dimensions ensures:
- Zero Awkward Cropping: Your core message, branding, and text remain fully visible.
- Maximum Visual Impact: High-resolution, properly scaled images instantly signal professionalism and credibility.
- Higher Engagement: Clean, easy-to-read graphics keep users pausing on your post instead of scrolling past.

Deep Dive: Choosing the Right Format for Your Goal
1. The Vertical Powerhouse (1080 x 1350 px)
If you want to dominate the screen, portrait mode (4:5 aspect ratio) is your best friend. Because the majority of professionals consume LinkedIn on mobile phones, vertical images take up significantly more vertical real estate in the feed. This forces the user to pause longer as they scroll past, dramatically increasing your chances of capturing attention.
2. The Classic Square (1080 x 1080 px)
Square posts are versatile, safe, and reliable. They look equally balanced on desktop widescreen monitors and mobile screens. They are ideal for bold typography, headshots, infographics, and brand announcements.
3. Carousel / Document Posts (PDF format)
Carousels continue to be one of the highest-performing content formats on LinkedIn. Instead of uploading a standard image file, you create multiple slides in a design tool (like Canva), download them as a PDF, and upload the PDF as a document post.
- Pro Tip: Stick to a 1080 x 1350 px portrait size for your carousel slides to give readers a rich, magazine-like reading experience.
Best Practices for Designing LinkedIn Graphics
Getting the pixel dimensions right is only half the battle. Follow these quick tips to make your visuals truly stand out:
- Keep Text Minimal: Avoid turning your image into a mini-essay. Use a bold, punchy headline (under 6-8 words) and let your accompanying text post do the heavy lifting.
- Mind the Safe Zones: Keep crucial elements (logos, text, key focal points) centered or safely away from the absolute edges so they aren’t accidentally clipped on smaller displays.
- Prioritize Contrast: Ensure your text color stands out sharply against your background. Many professionals browse LinkedIn in dark mode or outdoors in bright sunlight—low contrast makes graphics unreadable.
- Export in High Quality: Always save your designs as PNG files for graphics with sharp lines and text, and JPEG for photographs. Avoid uploading compressed or blurry images.
