The Ultimate Guide to LinkedIn Post Dimensions (2026 Edition)

In the world of professional networking, first impressions matter more than ever. When users scroll through their LinkedIn feeds, high-quality, visually striking graphics are often what stop them in their tracks. However, nothing screams “unprofessional” quite like a pixelated graphic, a awkwardly cropped headshot, or text that gets cut off mid-sentence.

To help your content stand out and look polished, here is the complete, up-to-date guide to LinkedIn post dimensions and image sizes.

Why LinkedIn Image Dimensions Matter

LinkedIn’s algorithm favors engagement, and visual content consistently outperforms plain text. But aesthetics aside, using the correct aspect ratio and pixel dimensions ensures that:

• Your text and visuals remain legible: Cropping ruins infographics and meme-style text posts.
• Your branding looks consistent: Clean, sharp images reflect positively on your personal brand or company page.
• Your content optimizes across devices: What looks great on a desktop monitor also needs to render smoothly on mobile apps, where the vast majority of professionals view LinkedIn.

Standard LinkedIn Post Dimensions

Depending on what kind of story you are trying to tell, you will want to choose the right format. Here are the precise dimensions for the most common LinkedIn post types:

1. Single Image Posts (Square & Landscape)

The classic single-image post is a workhorse for announcements, quotes, and event promos.

• Square Image (Recommended): 1080 x 1080 pixels (1:1 Aspect Ratio)
  • Why use it: Square images take up a healthy amount of real estate on both mobile and desktop feeds without forcing the user to click to expand.
• Landscape/Horizontal Image: 1200 x 627 pixels (approx. 1.91:1 Aspect Ratio)
  • Why use it: Great for sharing blog post banners, website link previews, or cinematic landscape photography.

2. Vertical / Portrait Posts (The Feed Grabber)

If you want to maximize the screen space your post occupies in the mobile feed, vertical images are your best bet.

• Portrait Image: 1080 x 1350 pixels (4:5 Aspect Ratio)
  • Why use it: Because most professionals browse LinkedIn on their phones, vertical posts push neighboring text and distractions out of view, dramatically increasing your visibility and dwell time.

3. Document / Carousel Posts (PDF Carousels)

Carousels are among the highest-performing content formats on LinkedIn for education, storytelling, and deep-dive guides. When uploading a PDF as a document post, slide dimensions matter immensely:

• Square Slides: 1080 x 1080 pixels (1:1)
• Portrait Slides (Recommended): 1080 x 1350 pixels (4:5)
  • Tip: Keep your text margins clean, use large fonts, and avoid overcrowding individual slides to make swiping effortless.

4. Link Preview Images

When you paste a URL into a text post, LinkedIn automatically generates a link preview card.

• Link Preview Image: 1200 x 627 pixels
  • Tip: If the automatically pulled image looks blurry or cropped incorrectly, you can often customize it on your website’s Open Graph (OG) settings or upload a native image alongside a clean link.

Beyond the Feed: Profile & Cover Image Dimensions

Your overall profile setup dictates whether people trust your content enough to click “Follow” or “Connect.” Make sure your profile assets are also optimized:

• Personal Profile Picture: 400 x 400 pixels (minimum), though higher resolutions like 800 x 800 work well as long as it stays under the file size limit. Keep your face centered, as LinkedIn crops profile pictures into a circle.
• Personal Background / Banner Image: 1584 x 396 pixels (4:1 Aspect Ratio)
• Company Page Logo: 300 x 300 pixels
• Company Page Cover / Hero Image: 1128 x 191 pixels

Best Practices for Designing LinkedIn Visuals

1. Keep Critical Text Centered: Avoid placing important text, logos, or faces right near the edges of your graphics where UI overlays (like document navigation arrows or mobile cropping) might obscure them.
2. Watch the File Size: LinkedIn supports PNG, JPEG, and GIF formats for standard images (usually up to 5MB or 10MB depending on the type). Keep your files compressed so they load instantly on slower mobile networks.
3. Design for Mobile First: Over 60% of LinkedIn traffic originates from mobile devices. If your text is hard to read on a smartphone screen, your audience will simply scroll past.
4. Maintain Contrast: High-contrast color combinations make your graphics pop against LinkedIn’s clean white and gray interface.

By mastering these dimensions, you ensure that your hard work in copywriting and design isn’t undermined by awkward auto-cropping. Next time you schedule a campaign or share a carousel, use these specs to make your brand shine!
