The Ultimate Guide to LinkedIn Post Dimensions: Stop Getting Your Content Cropped

You’ve spent hours drafting a brilliant thought-leadership post, pairing it with a sleek graphic you designed down to the last pixel. You hit publish, feeling confident. Then, you look at it on your phone: the top of your headline is awkwardly cut off, the sides are pixelated, and your carefully centered logo is hidden behind a UI element.

What went wrong? You fell victim to bad dimensions.

LinkedIn is a visual and professional battleground. With over 60% of its traffic originating on mobile devices, platform layout quirks can make or break your reach. Using the correct dimensions ensures your brand looks sharp, trustworthy, and authoritative.

This comprehensive guide breaks down the optimal LinkedIn post dimensions for every format, keeping your feed looking pristine.

1. Single Image Posts: The Core Feed Formats

When uploading a single image to the LinkedIn feed, you have three primary aspect ratio choices. Each serves a different tactical purpose.

| Format | Recommended Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Portrait (Vertical) | 1080 × 1350 px | 4:5 | Text-heavy graphics, infographics, charts, and max mobile engagement |
| Square | 1080 × 1080 px (or 1200 × 1200 px) | 1:1 | Cross-platform posting, simple quote cards, and clean brand imagery |
| Landscape | 1200 × 627 px | 1.91:1 | Link previews, wide photography, and cinematic announcements |

Which one should you pick?

• Go Portrait (1080 × 1350 px) for maximum impact: Because mobile users scroll vertically, portrait images consume the most screen real estate, holding a viewer’s gaze longer.
• Go Square (1080 × 1080 px) for safety: If you plan to cross-post your graphic to X, Instagram, or Facebook, square is your safest compromise. It scales gracefully across desktop and mobile without unwanted surprises.

2. Document Posts & Carousels (PDF Slides)

Document uploads—commonly known as carousels—are one of the highest-performing content types on LinkedIn because they force users to swipe, drastically increasing “dwell time” (how long someone lingers on your post).

• Recommended Dimensions: 1080 × 1080 px (Square) or 1080 × 1350 px (Portrait).
• File Format: Export your presentation or slides as a PDF.
• Best Practice: Keep text sizes readable (at least 24pt equivalent) and maintain generous margins so LinkedIn’s side buttons don’t block your copy.

3. Video Specifications

Native video performs exponentially better on LinkedIn than sharing external YouTube or Vimeo links. Whether you are recording talking-head clips or promotional motion graphics, adhere to these guidelines:

• Landscape Video: 1920 × 1080 px (16:9 aspect ratio)
• Vertical/Portrait Video: 1080 × 1920 px (9:16 aspect ratio)
• Square Video: 1080 × 1080 px (1:1 aspect ratio)
• File Size & Limits: Up to 5 GB and a maximum length of 10 minutes (though concise videos under 30 seconds see the highest completion rates).
• Pro-Tip: Always burn captions directly into your video file. Most professionals browse LinkedIn at work with the sound muted by default.

4. Link Previews & Open Graph Images

When you paste a URL into a LinkedIn post text box, the platform automatically scrapes an image from that webpage to generate a thumbnail preview.

• Recommended Dimensions: 1200 × 627 px (1.91:1)
• The Fix: If your link previews always look blurry or cropped incorrectly, ensure your website’s Open Graph (OG) meta tags are hard-coded to a 1200 × 627 pixel asset.

5. Profile and Company Page Assets

Your personal profile and company page act as your digital storefront. Blurry banners or cut-off profile pictures instantly erode professional trust.

• Personal Profile Picture: 400 × 400 px (1:1 ratio, cropped into a circle—keep your face dead-center).
• Personal Banner/Cover Photo: 1584 × 396 px (4:1 ratio). Note: On desktop, your profile picture overlaps the bottom-left corner of your banner, so keep vital text and logos aligned toward the right side.
• Company Page Cover Photo: 1128 × 191 px.

Quick Design Rules to Live By

1. Mind the Compression: Always export your graphics as PNG if they contain sharp typography, UI mockups, or logos to prevent ugly artifact blurring. Use JPG for photographic backgrounds.
2. Design for Mobile First: Since the vast majority of your audience views LinkedIn on a smartphone, tiny fonts and cluttered margins will cause instant drop-offs. Keep text large, bold, and high-contrast.
3. Check Before You Post: Save your layouts as templates in Canva, Figma, or Photoshop using these exact dimensions. A minute spent double-checking your pixel ratios guarantees your content looks polished and commands the attention it deserves.
