The Ultimate Guide to LinkedIn Post Dimensions and Image Sizes

When it comes to building a professional brand on LinkedIn, visual content stands out. Whether you are sharing a thought-leadership article, an infographic, or a quick career update, using the correct image dimensions ensures your visuals look sharp, professional, and uncropped.

Poorly sized images often suffer from awkward scaling or get cut off on mobile devices, which can detract from your message. This guide breaks down the exact dimensions you need for every type of LinkedIn post and profile element.

1. LinkedIn Feed Post Dimensions

LinkedIn supports three primary aspect ratios for standard feed images. Choosing the right one depends on the nature of your content:

| Format | Recommended Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Landscape | 1200 × 627 px | 1.91:1 | Link previews, formal announcements, landscape photography |
| Square | 1080 × 1080 px | 1:1 | Infographics, quote cards, clean multi-image grids |
| Portrait | 1080 × 1350 px | 4:5 | Maximizing mobile screen space and boosting engagement |

• Landscape (1200 × 627 px): This is the default format for shared link previews. It renders cleanly on desktop screens, though it takes up less vertical space on mobile feeds.
• Square (1080 × 1080 px): A versatile, foolproof choice. Square images command more attention than landscape posts and maintain a consistent look across both desktop and mobile platforms.
• Portrait (1080 × 1350 px): Because a vast majority of users browse LinkedIn on mobile devices, portrait images occupy the most vertical screen real estate. Creators looking to maximize view time and engagement frequently opt for this format.

2. Special Post Formats: Carousels and Video

Beyond standard static images, dynamic formats have distinct technical requirements:

• Carousel Posts (Document Shares): Carousels are uploaded as PDF documents where each page functions as a slide.
  • Recommended Size: 1080 × 1080 px (Square) or 1080 × 1350 px (Portrait) per slide.
  • Tip: Keep text well within the margins and use high-contrast fonts so slides remain legible when scaled down on smaller screens.
• Native Video Posts:
  • Recommended Resolution: 1920 × 1080 px (16:9 Landscape) or 1080 × 1080 px (Square).
  • File Limits: Supported formats include MP4, with file sizes up to 5 GB. Shorter, punchier videos generally achieve higher completion rates.

3. Profile and Cover Image Essentials

Your personal or company profile serves as your digital storefront. Make sure your core profile assets meet these exact specifications:

• Profile Photo: Minimum 400 × 400 px (1:1 ratio). LinkedIn crops this image into a circle, so make sure your face or primary logo is centered with plenty of breathing room around the edges.
• Profile Background Banner: 1584 × 396 px (4:1 ratio). Keep in mind that the circular profile picture overlaps the bottom-left corner of the banner on desktop viewports, so avoid placing critical text or logos there.

4. Quick Tips for Flawless Uploads

• File Formats: Use JPEG for standard photographs to keep file sizes manageable. Opt for PNG when your graphics include crisp text, sharp lines, or transparent elements. LinkedIn also supports WebP for feed uploads.
• File Size Caps: Keep single image files under 5 MB to 8 MB to prevent upload errors or long load times.
• Design Safely: Always place important text and key visual elements toward the center of your canvas. This ensures nothing gets unexpectedly clipped or hidden by platform UI elements across different devices.
