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

First impressions matter—especially on a professional platform like LinkedIn. Whether you are building your personal brand, positioning your company as an industry leader, or launching a targeted advertising campaign, visuals are the anchor of your content strategy.

An uncomfortably cropped banner, a blurry profile picture, or a pixelated infographic can instantly undermine your professional credibility. Conversely, crisp, perfectly dimensioned graphics signal attention to detail, polish, and authority.

This comprehensive guide breaks down the exact LinkedIn image sizes, aspect ratios, and optimization tips you need to master your visual presence.

Part 1: Personal Profile Image Sizes

Your personal profile is your digital handshake. Getting the dimensions right ensures you look sharp across both desktop monitors and mobile apps.

• Profile Picture

  • Optimal Dimensions: $400 times 400$ pixels (minimum $300 times 300$ pixels)
  • Aspect Ratio: 1:1 (Square, but cropped into a circle by LinkedIn)
  • Max File Size: 8 MB
  • Pro Tip: Keep your face centered, occupying about 60% of the frame. Avoid putting crucial details near the extreme corners, as LinkedIn’s circular crop will cut them off. Use a high-contrast background so your headshot stands out even as a tiny thumbnail in comment threads.

• Personal Background / Cover Banner

  • Optimal Dimensions: $1584 times 396$ pixels
  • Aspect Ratio: 4:1 (Landscape)
  • Max File Size: 8 MB
  • Pro Tip: Your banner behaves differently depending on the device. On desktop, it spans wide; on mobile devices, the edges are automatically cropped. Keep all core text, branding, and imagery within a centered safe zone to prevent awkward cut-offs on smartphones.

Part 2: Company Page Image Sizes

If you manage a business page, visual consistency reinforces brand trust and corporate identity.

• Company Logo

  • Optimal Dimensions: $300 times 300$ pixels (or $400 times 400$ pixels)
  • Aspect Ratio: 1:1 (Square)
  • Max File Size: 4 MB
  • Pro Tip: Upload a transparent PNG when possible. Because company logos appear alongside every post update and in search results (often scaled down to $40 times 40$ pixels), test your design at a small scale to ensure text remains legible.

• Company Cover / Page Banner

  • Optimal Dimensions: $1128 times 191$ pixels
  • Aspect Ratio: ~6:1 (Ultra-wide landscape)
  • Max File Size: 4 MB
  • Pro Tip: This banner is much narrower than a personal banner. Avoid cluttered designs; stick to a clean background graphic, your company tagline, or a subtle call-to-action.

• “Life Tab” Custom Modules

  • Module Image Dimensions: $1128 times 376$ pixels (3:1 aspect ratio)
  • Custom Modules Image Dimensions: $502 times 282$ pixels
  • Max File Size: 4 MB per image

Part 3: Feed Post Image Sizes

Content in the LinkedIn feed competes fiercely for attention. Selecting the right aspect ratio allows you to maximize screen real estate and stop the scroll.

• Square Posts (The Versatile Standard)

  • Optimal Dimensions: $1080 times 1080$ pixels (or $1200 times 1200$ pixels)
  • Aspect Ratio: 1:1
  • Best For: Product photos, quotes, and standard cross-platform graphics. It renders predictably well across both desktop and mobile feeds.

• Vertical / Portrait Posts (The Engagement Winner)

  • Optimal Dimensions: $1080 times 1350$ pixels
  • Aspect Ratio: 4:5
  • Best For: Tall infographics, multi-step breakdowns, and data charts.
  • Why it works: Vertical images capture the most vertical real estate on mobile feeds, forcing users to pause and engage. Avoid going taller than a 4:5 ratio (such as 9:16 stories formats), or LinkedIn will automatically crop your image from the bottom.

• Landscape Posts & Link Previews

  • Optimal Dimensions: $1200 times 627$ pixels
  • Aspect Ratio: 1.91:1
  • Best For: Sharing external blog links, data visualizations, and horizontal landscape photography.
  • Pro Tip: When sharing a link, make sure your destination website utilizes Open Graph (OG) meta tags configured to this exact $1200 times 627$ specification so LinkedIn pulls a pristine thumbnail preview instead of a compressed or broken image.

Part 4: Carousels & Document Posts

Document posts (uploaded as PDFs that users swipe through like carousels) consistently drive some of the highest engagement rates on LinkedIn.

• Slide Dimensions:
  • Square: $1080 times 1080$ pixels (1:1 aspect ratio)
  • Vertical: $1080 times 1350$ pixels (4:5 aspect ratio)
• Max File Size & Limit: Up to 100 MB, supporting up to 300 pages (though 8 to 15 pages is the sweet spot for engagement).
• Pro Tip: Always export your carousel frames directly as a high-quality PDF rather than relying on automated PowerPoint conversions, which often scramble fonts and margins. Keep a consistent layout format across every slide—mixing aspect ratios will cause LinkedIn to apply awkward white padding bars.

Part 5: Video & Article Banners

• Native Video Posts

  • Recommended Resolution: $1920 times 1080$ pixels (Landscape, 16:9) or $1080 times 1920$ pixels (Portrait, 9:16)
  • Max File Size: 5 GB
  • Duration: 3 seconds to 10 minutes
  • Video Thumbnails: Custom thumbnails should be uploaded at $1920 times 1080$ pixels (JPEG or PNG, under 2 MB).

• LinkedIn Articles (Cover Images)

  • Optimal Dimensions: $1920 times 1080$ pixels
  • Aspect Ratio: 16:9
  • Pro Tip: This header acts as the hero image at the top of your long-form article and serves as its primary preview thumbnail when shared across the network.

Golden Rules for Crisp LinkedIn Visuals

1. Never Upscale Small Images: If you start with a tiny image and stretch it to meet LinkedIn’s recommended dimensions, it will pixelate and look blurry. Always design at or above the target resolution.
2. Choose the Right File Format: Use PNG for graphics containing text, logos, or sharp UI lines to prevent compression artifacts. Use JPEG for photographs and complex color gradients.
3. Design for Mobile First: Over 60% of LinkedIn traffic originates on mobile devices. Always check your graphics on a smaller screen to ensure text is easily readable and primary focal points aren’t clipped.
