The Ultimate Guide to LinkedIn Post Dimensions (2026 Edition)

In the world of professional networking, first impressions happen in milliseconds. When scrolling through a crowded LinkedIn feed, posts with eye-catching, perfectly sized visual assets instantly grab attention, drive engagement, and elevate your personal brand or company page.

Conversely, awkward cropping, pixelation, or cut-off text can make even the most insightful content look amateurish.

Whether you’re sharing a company update, publishing a thought-leadership article, designing a carousel, or updating your profile banners, here is your definitive, up-to-date guide to mastering LinkedIn post dimensions and image sizes.

Why LinkedIn Image Dimensions Matter

LinkedIn’s algorithm favors engagement—and content that looks polished and professional naturally earns more clicks, comments, and shares. Furthermore, LinkedIn compresses and scales uploads differently across desktop and mobile devices. Using the correct aspect ratio ensures that your key messaging and visuals remain crisp and fully visible no matter how your audience is viewing your content.

1. Standard Single Image Posts (Feed Links & Photos)

When you upload a standalone photo or share a link with a preview image, the dimensions dictate how much screen real estate your post commands.

• Square Image (Most Versatile):
  • Dimensions: 1080 x 1080 pixels
  • Aspect Ratio: 1:1
  • Best For: General announcements, quotes, infographics, and day-to-day posts. Square images look great on both desktop and mobile feeds.
• Vertical / Portrait Image (Best for Engagement):
  • Dimensions: 1080 x 1350 pixels (or 1080 x 1500 pixels)
  • Aspect Ratio: 4:5 (or 9:16)
  • Best For: Maximizing mobile screen space. Portrait images push competing posts further down the screen, forcing viewers to pause and look at your content.

2. LinkedIn Document Posts (Carousels & PDFs)

Document posts—often referred to as carousels or slide decks—are currently one of the highest-performing content formats on LinkedIn. Users swipe through slides, which keeps them lingering on your post longer (a major signal to the algorithm).

• Square Carousel: 1080 x 1080 pixels (1:1 ratio)
• Vertical Carousel (Recommended): 1080 x 1350 pixels (4:5 ratio)
  • Tip: Design your slides in tools like Canva or Figma using these exact dimensions, export them as a PDF, and upload the PDF directly as a “Document” post.

3. LinkedIn Link Share Previews

When you paste a URL into a LinkedIn post, it automatically generates a preview card with a thumbnail image.

• Link Preview Image:
  • Dimensions: 1200 x 627 pixels
  • Aspect Ratio: 1.91:1
  • Tip: Always ensure your website’s Open Graph (OG) image is optimized to these dimensions so that shared links always generate clean, uncropped preview cards.

4. LinkedIn Stories & Video Specs

While text and image carousels dominate, video and temporary visual content play a strong supporting role in B2B marketing.

• Native Video Dimensions:
  • Landscape: 1280 x 720 pixels (16:9)
  • Square: 1080 x 1080 pixels (1:1)
  • Vertical: 1080 x 1920 pixels (9:16)
  • Max File Size: 5 GB | Max Length: Up to 10 minutes (for native uploads).

5. Profile & Company Page Banners

Your feed posts are only part of the equation. Your profile or company page headers act as a digital storefront.

• Personal Profile Background / Banner:
  • Dimensions: 1584 x 396 pixels (4:1 ratio)
• Company Page Cover Image:
  • Dimensions: 1128 x 191 pixels (approx. 6:1 ratio)
• Profile Picture / Logo:
  • Dimensions: 400 x 400 pixels (minimum, displayed as a circle, so keep important details centered).

Pro-Tips for Flawless LinkedIn Visuals

1. Keep Text Centered: On mobile feeds, image edges can occasionally be slightly masked or cropped depending on the user’s screen size. Keep critical text and logos well within a safe central zone.
2. Mind the Contrast: Professional doesn’t have to mean boring, but high-contrast color palettes and legible font sizes (at least 24pt+ for slide headers) are vital for readability on smaller screens.
3. Export in High Quality: Always export your designs as PNG for crisp graphics and text, or high-quality JPG for photographic content.

By sticking to these dimensions, you ensure your content looks professional, commands attention in a busy feed, and positions your brand as credible and detail-oriented.
