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

When you spend hours crafting the perfect LinkedIn post, the last thing you want is for a poorly cropped graphic or a pixelated thumbnail to ruin your first impression. Visuals are powerful hooks on professional networks, but LinkedIn handles image rendering with specific rules that can make or break your design.

Whether you are sharing a data-heavy infographic, an industry announcement, or a casual team update, getting your dimensions right ensures your content looks sharp, professional, and optimized for engagement.

1. The Core LinkedIn Post Image Sizes at a Glance

Depending on the layout and where your audience is scrolling, LinkedIn supports three primary aspect ratios for standard feed images:

| Format | Recommended Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Square | $1080 times 1080text{ px}$ | $1:1$ | Versatile feed posts, quote graphics, infographics |
| Portrait (Vertical) | $1080 times 1350text{ px}$ | $4:5$ | Mobile-first content, step-by-step breakdowns, max engagement |
| Landscape (Horizontal) | $1200 times 627text{ px}$ | $1.91:1$ | Link previews, broad announcements, traditional banners |

2. Choosing the Right Format for Your Strategy

The Square Format ($1080 times 1080$ px)

• Why use it: Square is the ultimate “safe bet.” It renders consistently on both desktop and mobile devices without unexpected cropping. It occupies a balanced amount of visual real estate in the feed and works seamlessly if you plan to cross-post your visuals to Instagram or Facebook.
• Best for: Quotes, product highlights, and multi-image grid posts.

The Portrait Format ($1080 times 1350$ px)

• Why use it: If your goal is maximum engagement, portrait is your power move. Because over half of LinkedIn’s traffic is mobile-first, a $4:5$ ratio stretches down the phone screen, taking up valuable vertical space and physically pushing competing posts out of view.
• Best for: High-value infographics, frameworks, checklists, and dense thought-leadership carousels.

The Landscape Format ($1200 times 627$ px)

• Why use it: Landscape is LinkedIn’s legacy format and the standard for link previews. If you paste a URL into a post, LinkedIn automatically generates a preview card matching these dimensions.
• Best for: Sharing blog posts, news articles, press releases, or external content. (Note: If you use landscape for a standalone graphic, it leaves a lot of empty white space on mobile screens).

3. Beyond the Feed: Other Crucial LinkedIn Dimensions

A cohesive profile requires attention to more than just individual posts. Keep these specifications handy for branding your profile or company page:

• Personal Profile Picture: $400 times 400text{ px}$ ($1:1$ ratio). Keep your face centered, as LinkedIn displays profile photos inside a circular crop, cutting off the corners.
• Personal Background Banner: $1584 times 396text{ px}$ ($4:1$ ratio). Pro tip: Keep vital text and logos within a centered $1200 times 300text{ px}$ safety zone so they aren’t obscured by your profile picture or clipped on mobile viewports.
• Company Page Logo: $300 times 300text{ px}$ ($1:1$ ratio). Use a clean PNG with a transparent background to maintain sharpness across search results and notifications.
• Company Cover Banner: $1128 times 191text{ px}$. Note that company banners are much wider and shorter than personal banners, so design specifically for them rather than recycling assets.

4. Technical Specifications & Best Practices

To avoid automated compression, blurriness, or upload errors, stick to these platform guidelines:

• File Formats: Stick to JPEG or PNG for static images. PNG is generally preferred for graphics containing text or logos to prevent compression artifacts.
• File Size Limit: Keep your image files under 5MB for standard posts to guarantee fast loading speeds.
• The “Safe Zone” Rule: Never place critical text, borders, or logos right against the edge of your canvas. Different operating systems and device updates occasionally tweak rendering margins; a small inner buffer prevents elements from getting clipped.
• Never Upscale Small Images: If you start with a tiny image and stretch it to fit $1080 times 1080text{ px}$, LinkedIn’s algorithm will display a pixelated, blurry result. Always design at the recommended resolution or higher.

Summary Checklist

Before hitting “Post,” double-check that your graphic matches the layout you intended. If you want people to stop scrolling on their phones, lean into portrait ($1080 times 1350$); if you want clean, predictable formatting across all devices, stick to square ($1080 times 1080$). Correct sizing takes only a few extra seconds in tools like Canva or Photoshop, but it pays off with a polished, professional brand image.
