The Ultimate Guide to LinkedIn Post Dimensions (2026 Edition)

In the crowded landscape of professional social media, standing out requires more than just a clever hook or an insightful takeaway—it demands visual polish. Whether you are building your personal brand or managing a corporate page, the images and videos you share are often the first thing a user notices as they scroll through their feed.

If your visuals appear blurry, stretched, or awkwardly cropped, it signals a lack of attention to detail. To ensure your content always looks professional, you need to master the exact image and video dimensions required by LinkedIn.

Here is everything you need to know about optimizing your visual assets for maximum engagement.

Why LinkedIn Image Dimensions Matter

LinkedIn’s algorithm favors content that captures and holds user attention. When your images fit the platform’s native aspect ratios perfectly:

• No Awkward Cropping: Your core message, branding, or faces won’t get cut off in the feed preview.
• Higher Engagement: Crisp, high-resolution visuals look professional and build immediate trust with your network.
• Optimized Real Estate: Vertical and square images take up more vertical space on mobile screens, giving your post a higher chance of stopping the scroll.

1. Standard Shared Image Posts (Single Image)

When you share a single photo or graphic directly to your feed, it appears as a preview card.

• Landscape (Horizontal): 1200 × 627 pixels (1.91:1 aspect ratio)
• Square: 1080 × 1080 pixels (1:1 aspect ratio)
• Vertical (Portrait): 1080 × 1350 pixels (4:5 aspect ratio)

Tip: While landscape is classic, square and vertical images occupy significantly more screen space on mobile devices, making them ideal for driving higher click-through and engagement rates.

2. Carousel Posts (Document Uploads)

Document carousels (PDF uploads that users can swipe through) are currently one of the most powerful organic reach tactics on LinkedIn.

• Square Carousel: 1080 × 1080 pixels (1:1 aspect ratio)
• Portrait Carousel: 1080 × 1350 pixels (4:5 aspect ratio)
• Recommended File Format: PDF (exported as high-resolution images per page)

Keeping your slides clean, legible, and formatted to these exact dimensions ensures text-heavy carousels are easy to read on both desktop and mobile.

3. Link Preview Images

When you paste a URL into a LinkedIn post, the platform automatically generates a thumbnail preview based on the website’s Open Graph image tag.

• Recommended Size: 1200 × 627 pixels (1.91:1 aspect ratio)

Pro-Tip: Always check how your link preview renders before publishing. If the image looks cropped or low-res, consider creating a custom graphic and uploading it as a native image post while placing the link in the comments or text body (depending on your strategy).

4. LinkedIn Stories & Video Specs

Video content continues to grow rapidly on the platform. Whether you are uploading native video or running video ads, stick to these guidelines:

• Video Resolution: Up to 1080p (1920 × 1080 or 1080 × 1920 for vertical)
• Aspect Ratios: 16:9 (horizontal), 1:1 (square), or 9:16 (vertical)
• File Size: Up to 5 GB
• Length: Anywhere from 3 seconds to 30 minutes

5. Profile and Cover Image Dimensions (The Basics)

Your personal or company profile is your digital storefront. Don’t let poorly sized branding elements undermine your credibility:

• Personal Profile Picture: 400 × 400 pixels (minimum)
• Personal Background Banner: 1584 × 396 pixels (4:1 aspect ratio)
• Company Logo: 300 × 300 pixels
• Company Cover Image: 1128 × 191 pixels

Quick Best Practices for LinkedIn Visuals

1. Stick to Safe Zones: Avoid placing essential text or logos right along the extreme edges of your templates, as slight UI padding differences can occasionally clip them.
2. Export in High Quality: Save your graphics as PNGs for sharp text and crisp lines, or high-quality JPEGs for photographs.
3. Design for Mobile First: Over 60% of LinkedIn traffic originates from mobile devices. If your text is too small to read on a smartphone screen, scale it up.

By aligning your content creation workflow with these exact dimensions, you’ll ensure your brand always looks polished, professional, and impossible to ignore.
