The Ultimate Guide to LinkedIn Image Sizes: Master Every Dimension for Maximum Engagement

You’ve spent hours drafting a brilliant thought-leadership post, crafting the hook, and refining your insights. But when you hit publish, your accompanying graphic looks blurry, gets awkwardly cropped at the edges, or worse—cuts your face right out of the frame.

We’ve all been there. On a platform driven by professional presentation, visual blunders can instantly undermine your credibility. Because LinkedIn resizes and compresses images differently across desktop screens, mobile apps, and specific profile modules, nailing the exact pixel dimensions is non-negotiable.

This comprehensive guide breaks down the exact LinkedIn image sizes you need to know to make your personal brand and company page look sharp, professional, and impossible to ignore.

1. Feed Post Image Sizes (Where Engagement Happens)

Your feed content dictates your reach. Depending on how you want your visual to display, you have three primary aspect ratio choices for single images:

| Post Format | Recommended Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Square (Default) | $1080 times 1080$ px | 1:1 | Product showcases, quote cards, cross-platform sharing |
| Portrait (Mobile-First) | $1080 times 1350$ px | 4:5 | Infographics, step-by-step guides, high-impact visuals |
| Landscape (Link Preview) | $1200 times 627$ px | 1.91:1 | Blog link shares, website previews, horizontal photography |

• Pro Tip on Portrait Mode: Over half of all LinkedIn browsing happens on mobile devices. A vertical $4:5$ image ($1080 times 1350$ px) takes up the maximum vertical real estate allowed in the mobile feed, forcing competing posts out of view. If you want eyes on your content, portrait is your secret weapon.

2. Personal Profile Image Dimensions

Your profile is your digital storefront. If your personal branding graphics are fuzzy, potential clients or employers will assume a lack of attention to detail.

• Profile Picture: $400 times 400$ pixels (minimum $300 times 300$ px).
  • The Trap: LinkedIn crops your square photo into a circle. Center your face and keep vital logos or details away from the extreme corners, or they will get chopped off.
• Background Banner (Cover Photo): $1584 times 396$ pixels ($4:1$ ratio).
  • The Mobile Trap: While your banner looks expansive on a desktop browser, LinkedIn automatically crops the left and right margins on mobile phones. Keep all essential text, logos, and focal points within a centered safe zone to prevent important information from disappearing on small screens.

3. Company Page Image Specifications

Running a company page requires a slightly different set of specs to look official and authoritative:

• Company Logo: $300 times 300$ pixels (Square, 1:1). Use a clean PNG file with a transparent background so it looks crisp in search results and notifications.
• Company Cover Photo: $1128 times 191$ pixels (Ultra-wide landscape). Unlike personal banners, this is a much shorter strip, so design it natively rather than trying to reuse your personal banner assets.

4. Carousels and Documents (The Document Post Hack)

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

• Document Slide Size: $1080 times 1080$ pixels (Square) or $1080 times 1350$ pixels (Vertical).
• Format: Always upload as a clean PDF file rather than a PowerPoint conversion to prevent formatting shifts and text pixelation.

Quick Golden Rules for Crisp LinkedIn Graphics

1. Never Upscale Small Images: If you stretch a tiny image to fit $1200$ pixels wide, LinkedIn’s compression algorithm will turn it into a pixelated mess. Always design at or above the target resolution.
2. Choose the Right File Format: Use JPEG for standard photographs (smaller file sizes) and PNG for graphics containing text, UI mockups, or logos to keep lines sharp.
3. Mind the Edges: When designing carousels or text-heavy infographics, leave a generous margin around all four sides. Different device viewports crop edges differently.

By sticking to these exact measurements, you’ll ensure your content always looks clean, intentional, and optimized to stop the scroll.
