The Ultimate Guide to LinkedIn Image Sizes: Dimensions, Specs, and Best Practices

First impressions matter. On LinkedIn, your visual assets—from your personal profile header to your daily feed posts—speak volumes about your professionalism before anyone reads a single word of your headline.

However, uploading an image without checking its dimensions is a gamble. LinkedIn’s aggressive compression and auto-cropping algorithms can easily chop off your logo, blur your text, or turn a carefully designed infographic into an unreadable mess.

This comprehensive guide breaks down the exact LinkedIn image sizes you need for your profile, company pages, and feed content to ensure your brand always looks sharp and intentional.

1. Personal Profile Image Dimensions

Your profile photo and background banner are the twin pillars of your personal brand. Because they appear everywhere from search results to comment threads, getting the dimensions right is non-negotiable.

• Profile Photo:

  • Recommended Size: 400 x 400 pixels (1:1 aspect ratio).
  • Max File Size: 8 MB.
  • Formats: JPG or PNG.
  • Pro Tip: LinkedIn displays your profile picture inside a circular crop. Center your face, keep vital details away from the corners, and use a high-resolution file so it remains crisp when scaled down in comment sections.

• Background Banner (Header):

  • Recommended Size: 1584 x 396 pixels (4:1 aspect ratio).
  • Max File Size: 8 MB.
  • Formats: JPG, PNG, or non-animated GIF.
  • Pro Tip: Watch out for the lower-left overlap zone. Your profile photo and headline sit directly over the bottom-left portion of the banner on desktop (and shift toward the center-left on mobile), so keep text and critical logos positioned on the right side.

2. Feed Post Image Sizes

Your feed content dictates your day-to-day engagement. With over 60% of LinkedIn users browsing on mobile devices, choosing the right aspect ratio determines how much screen estate your post commands.

| Post Format | Recommended Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Landscape | 1200 x 627 px | 1.91:1 | Link shares and external URL previews |
| Square | 1080 x 1080 px (or 1200 x 1200 px) | 1:1 | Universal posting, infographics, quote cards |
| Portrait | 1080 x 1350 px | 4:5 | Maximizing mobile screen space and driving high engagement |

The Mobile Advantage: While landscape is the default size for link previews, portrait (4:5) posts stretch down further on mobile screens, pushing competing updates out of view and capturing user attention longer.

3. Carousels, Documents, and Video Specs

Rich media formats like multi-slide PDFs (carousels) and native videos require specific structural layouts to render correctly across desktops and apps.

• Carousel / Document Posts (PDF Slides):

  • Recommended Dimensions: 1080 x 1080 pixels (Square, 1:1).
  • File Limits: Max 10 MB per document; up to 300 pages (though 5 to 10 slides is optimal for engagement).
  • Pro Tip: Square slides scale reliably without unexpected margin cropping on mobile devices.

• Native Video:

  • Recommended Dimensions: 1920 x 1080 pixels (16:9 Landscape) or 1080 x 1080 pixels (1:1 Square). Vertical video (4:5 or 9:16) is also supported.
  • Max File Size: Up to 5 GB.
  • Formats: MP4 or MOV.

4. Company Pages and Advertising Specs

If you manage a business page or run paid marketing campaigns, the specifications differ slightly from personal accounts:

• Company Page Cover Image: 1128 x 191 pixels (Wide strip format; design specifically for this layout rather than reusing a personal banner).
• Company Logo: 300 x 300 pixels (Keep it high-contrast and centered in a transparent PNG file).
• Sponsored Content / Single Image Ads: 1200 x 627 pixels (1.91:1 ratio) to ensure clean rendering across desktop sidebars and mobile newsfeeds.

Pro Tips for Flawless LinkedIn Visuals

1. Choose the Right File Format: Use JPEG for photographs and complex color gradients (smaller file size). Use PNG for graphics, charts, screenshots, and text-heavy assets to prevent compression artifacts around letters and lines.
2. Respect the Safe Zones: Always leave a generous margin (at least 40–50 pixels) around the edges of your text graphics. Different screen resolutions handle outer margins differently, and tight text risks getting clipped.
3. Mind the 5MB Limit: Keep standard feed images under 5 MB to maintain quick loading times and avoid platform compression failure.
4. Preview Before You Publish: Always upload your asset and check the mobile preview option before clicking post. Catching a misaligned graphic or an awkward crop beforehand saves you from having to delete and re-upload.
