The Ultimate Guide to LinkedIn Post Dimensions: Master Your Visuals for Maximum Engagement

In the fast-paced world of professional networking, first impressions happen in milliseconds. When a user scrolls through their LinkedIn feed, high-quality, perfectly proportioned visuals are what make them stop scrolling and lean in.

However, uploading an image that has been awkwardly cropped or compressed into pixelated blurriness can instantly undermine your professional credibility. To ensure your content always looks sharp, polished, and purposeful, here is the complete, up-to-date breakdown of LinkedIn post dimensions and design specifications.

Quick Reference: LinkedIn Feed Post Sizes

Choosing the right format depends on how much screen real estate you want to command. Here are the core dimensions for single-image and link posts:

| Post Type | Recommended Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Square Post | 1200 × 1200 px | 1:1 | Balanced feed presence, infographics, and quotes |
| Landscape Post | 1200 × 627 / 628 px | 1.91:1 | Standard photos and external URL link previews |
| Portrait / Vertical | 1080 × 1350 px (or 1200 × 1500 px) | 4:5 | Capturing maximum screen space on mobile devices |

Deep Dive: Choosing the Right Feed Format

1. Square Posts (1200 × 1200 px)

Square images offer a safe, reliable balance. They render predictably across desktop displays and mobile phones without aggressive auto-cropping. They are ideal for clean data visualizations, corporate announcements, and single-focus photos.

2. Portrait Posts (1080 × 1350 px)

If your primary goal is engagement, vertical formats win. Because over 60% of LinkedIn users browse via mobile devices, portrait images occupy significantly more vertical space on a smartphone screen, pushing competing posts out of view and driving higher interaction rates.

3. Landscape Posts & Link Previews (1200 × 627 px)

This is the classic wide format and the standard for automatically generated link previews when sharing articles or blog posts. Keep your core messaging centered horizontally, as minor side-cropping can occur on smaller displays.

Beyond Standard Images: Carousels, Videos, and Profiles

Carousel Posts (Document Uploads)

Document carousels (uploaded as PDFs) continue to be one of the highest-performing content formats on LinkedIn for thought leadership.

• Recommended Slide Size: 1080 × 1080 px (Square) or 1080 × 1350 px (Portrait)
• Format: Multi-page PDF
• Tip: Keep fonts legible (minimum 24px equivalent) so readers can digest slide decks seamlessly on mobile.

Video Specifications

Moving content requires a bit more breathing room regarding file size and orientation:

• Dimensions: 1920 × 1080 px (Landscape 16:9) or 1080 × 1080 px (Square)
• Max File Size: Up to 5GB (though faster, optimized files load more smoothly)
• Duration: From 3 seconds up to 10 minutes

Profile & Page Assets

Your personal branding extends far beyond individual posts. Keep your core profile dimensions optimized:

• Personal Profile Photo: 400 × 400 px (displayed as a circle, so keep faces/logos centered)
• Personal Background Banner: 1584 × 396 px (4:1 ratio)
• Company Page Logo: 400 × 400 px
• Company Page Cover Image: 1128 × 191 px

Best Practices for Crisp, Professional Visuals

• Watch the File Size: LinkedIn caps standard photo uploads at 5MB. Export graphics as PNG for crisp text lines, and use high-quality JPEGs for photographs to keep file sizes manageable.
• Respect the “Safe Zones”: Never place critical text, logos, or faces right along the extreme edges of your canvas. Different platforms and dynamic viewports can occasionally clip outer borders.
• Preview Before Publishing: Always use LinkedIn’s preview stage or test a draft on your mobile device before sending content live. Ensuring your layout looks pristine on a smartphone guarantees it will look great everywhere else.
