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

First impressions matter, and on LinkedIn, your visuals speak volumes before a single word of your profile or post is read. Whether you are polishing your personal brand, scaling a company page, or designing high-converting ad creatives, pixelation, awkward cropping, and blurry compression can instantly undermine your professional credibility.

Because LinkedIn dynamically adjusts layouts for desktop and mobile devices, nailing your image dimensions is both an art and a science. This complete, up-to-date cheat sheet covers every standard LinkedIn image size to help you keep your digital presence sharp.

1. Personal Profile Images

Your personal profile is your digital handshake. These two core assets define your personal brand:

• Profile Photo:
  • Recommended Dimensions: 400 × 400 pixels (minimum 200 × 200 px)
  • Aspect Ratio: 1:1 (Square upload)
  • Max File Size: 8 MB
  • Pro Tip: LinkedIn automatically crops your square image into a circle. Keep your face centered, filling roughly 60% of the frame, and ensure your corners are free of essential details so they aren’t clipped out.
• Personal Background Banner:
  • Recommended Dimensions: 1584 × 396 pixels
  • Aspect Ratio: 4:1 (Landscape)
  • Max File Size: 8 MB
  • Pro Tip: Desktop and mobile devices crop background banners differently. Your profile picture sits in the lower-left corner on desktop, while mobile views pinch the sides. Keep your core graphics and text centered to ensure a clean look across all screens.

2. Company Page Assets

Building authority for a business requires matching strict corporate branding standards across multiple structural blocks:

• Company Logo:
  • Recommended Dimensions: 300 × 300 pixels (minimum 300 × 300 px)
  • Aspect Ratio: 1:1 (Square)
  • Max File Size: 3 MB
  • Pro Tip: Use a PNG format with a transparent or solid background. Test how your logo looks scaled down to tiny comment thumbnails (48 × 48 pixels) to ensure legibility.
• Company Cover Banner:
  • Recommended Dimensions: 1128 × 191 pixels
  • Aspect Ratio: ~5.91:1 (Ultra-wide landscape)
  • Max File Size: 3 MB
• Life Tab Hero Image (Career Pages):
  • Recommended Dimensions: 1128 × 376 pixels
  • Aspect Ratio: 3:1

3. Feed Post Image Sizes

The LinkedIn feed supports multiple layout orientations. Choosing the right format depends heavily on whether your audience is primarily viewing content on mobile phones or office desktops:

• Square Posts (1:1 Ratio):
  • Recommended Dimensions: 1200 × 1200 pixels
  • Best for: Standalone screenshots, quotes, and product shots. This is the safest versatile layout for multi-platform cross-posting.
• Portrait / Vertical Posts (4:5 Ratio):
  • Recommended Dimensions: 1080 × 1350 pixels
  • Best for: Infographics, data visualizations, and text-heavy summaries. Vertical posts take up the most vertical screen estate on mobile feeds, driving significantly higher engagement.
• Landscape Posts (1.91:1 Ratio):
  • Recommended Dimensions: 1200 × 627 pixels
  • Best for: Event photos, wide-angle team shots, or widescreen landscape graphics.

4. Documents, Articles, and Link Previews

Content sharing extends beyond standard photos. If you’re leveraging long-form formats, keep these dimensions in mind:

• Document Carousels (PDF Uploads):
  • Recommended Dimensions: 1080 × 1080 pixels (Square) or 1920 × 1080 pixels (Landscape)
  • Max File Size: 100 MB (up to 300 pages, though 6–12 pages is the sweet spot for engagement).
• Shared Link Previews / Open Graph (OG) Images:
  • Recommended Dimensions: 1200 × 627 pixels (1.91:1)
  • Pro Tip: Always configure your website’s Open Graph meta tags to pull a custom 1200 × 627 px image. Links with missing or undersized thumbnail images collapse into a tiny side icon, severely dropping click-through rates.
• Articles and Newsletter Headers:
  • Article Featured Image: 1200 × 644 pixels
  • Newsletter Header Image: 1280 × 720 pixels (16:9 ratio)

Pro-Tips for Flawless Visuals

1. Never Upscale Small Images: If your raw image is too small, do not stretch it to meet LinkedIn’s dimensions; this introduces heavy blur and pixelation. Always design or export your assets at native resolution.
2. Mind the Color Formats and Compression: Export JPEGs at high quality (85%–95%) and use PNG-24 for graphics featuring crisp typography or sharp vectors to prevent compression artifacts.
3. Always Preview: Before pushing a major banner or ad live, check how it renders across both desktop browsers and the mobile app to ensure your text and logos remain entirely within safe zones.
