The Ultimate Guide to LinkedIn Post Image Sizes (2026 Edition)

When you spend hours crafting the perfect LinkedIn post—polishing the hook, refining your insights, and formatting for readability—the last thing you want is for your accompanying image to look cropped, pixelated, or awkwardly stretched.

Visuals are no longer optional on LinkedIn; they are essential for stopping the scroll in a crowded feed. Posts with images consistently generate higher engagement, more comments, and broader reach. However, LinkedIn’s feed layout is notoriously finicky. If you upload an image with the wrong dimensions, LinkedIn will automatically crop or resize it, often cutting off key text, faces, or brand logos right where it hurts most.

To ensure your visuals always look professional and polished, here is the complete, definitive guide to LinkedIn post image sizes for 2026.

1. Single Image Posts (Standard Link or Photo Posts)

When you share a standalone photo or upload an image to accompany your text update, you have two primary layout choices depending on the orientation of your image:

• Landscape (Horizontal): 1200 x 627 pixels (Aspect ratio: ~1.91:1)
  • Best for: General photography, landscape shots, and website preview thumbnails.
  • Tip: While landscape images take up less vertical space in the mobile feed, they are easier to scroll past quickly.
• Square: 1200 x 1200 pixels (Aspect ratio: 1:1)
  • Best for: Clean graphics, product shots, quotes, and versatile branding.
  • Tip: Square images offer a great balance between desktop and mobile visibility.
• Vertical (Portrait): 1080 x 1350 pixels (Aspect ratio: 4:5)
  • Best for: Maximizing screen real estate on mobile devices.
  • Tip: Because most professionals view LinkedIn on their phones, vertical posts take up more vertical pixels in the feed, forcing users to pause and engage with your content longer.

2. LinkedIn Documents (Carousels & PDFs)

Document posts—often referred to as carousels—are one of the most powerful organic growth formats on LinkedIn. They allow users to swipe through multiple pages of insights, step-by-step guides, or data breakdowns.

• Recommended Size: 1080 x 1350 pixels (Vertical / 4:5 aspect ratio) or 1080 x 1080 pixels (Square / 1:1 aspect ratio).
• File Format: PDF, DOC, or DOCX (PDF is strongly recommended to preserve exact formatting).
• Max File Size: Up to 100 MB (or usually up to 300 pages).

Pro-Tip for Carousels: Keep your font size large (at least 24pt–32pt) and leave ample breathing room (margins) around the edges. This ensures that text doesn’t touch the edge of the screen and remains easily readable on smaller mobile displays.

3. Link Preview Images (When Sharing Articles or Blogs)

When you paste a URL into a LinkedIn post text box, LinkedIn automatically crawls the page and generates a link preview card with an image.

• Recommended Size: 1200 x 627 pixels (Aspect ratio: ~1.91:1)
• Crucial Note: Ensure your website or blog’s Open Graph (og:image) meta tag is set to this exact dimension. If your website image is too small (
