Mastering LinkedIn Post Dimensions: The Complete Cheat Sheet for Maximum Feed Impact

Publishing on LinkedIn without verifying your image specs is like wearing a tailored suit with unhemmed pants: the core message might be solid, but the presentation misses the mark. Pixelated visuals, awkward center crops, or text cut off mid-sentence instantly undermine professional credibility.

Because LinkedIn users consume content across diverse screen sizes—from ultrawide desktop monitors to compact smartphone displays—getting your visual ratios right is essential for maximizing engagement and capturing feed real estate.

Quick Reference: LinkedIn Post Dimensions at a Glance

| Content Type | Recommended Resolution | Aspect Ratio | Maximum File Size / Format |
| :— | :— | :— | :— |
| Portrait / Vertical Image | 1080 × 1350 px | 4:5 | 5 MB (JPG, PNG) |
| Square Image | 1080 × 1080 px (or 1200 × 1200 px) | 1:1 | 5 MB (JPG, PNG) |
| Landscape / Link Preview | 1200 × 627 px (or 1200 × 628 px) | 1.91:1 | 5 MB (JPG, PNG) |
| Document / Carousel Slide | 1080 × 1350 px (Vertical) or 1080 × 1080 px | 4:5 or 1:1 | 100 MB (PDF, PPTX) |
| Native Video | 1080 × 1920 px (Vertical) or 1920 × 1080 px | 9:16 or 16:9 | 5 GB (MP4, MOV) |

1. Single Image Feed Posts

When uploading a single visual to your feed, layout choice determines how much screen space your content occupies.

• Portrait (1080 × 1350 px | 4:5 Aspect Ratio): This is the high-visibility choice for mobile mobile feeds. Vertical images take up roughly 58% more screen area than standard landscape posts, forcing users to scroll past your visual for longer.
  • Pro Tip: Keep key graphics and text within the central safe area to ensure clean rendering on desktop feeds.
• Square (1080 × 1080 px or 1200 × 1200 px | 1:1 Aspect Ratio): The universal middle ground. Square assets translate seamlessly between desktop and mobile feeds without unexpected cropping, making them ideal for cross-platform campaign repurposing.
• Landscape (1200 × 627 px | 1.91:1 Aspect Ratio): Ideal for charts, detailed infographics, or photo horizontal photography. While it takes up less vertical screen real estate, it avoids letterboxing on desktop screens.

2. Document & Carousel Posts (PDF Uploads)

Multi-slide document posts consistently drive high engagement on LinkedIn. Rather than using standard image carousels, creators typically design slides in Canva or Figma and upload them as a seamless PDF file.

• Optimal Dimensions: 1080 × 1350 pixels (4:5 vertical).
• Alternative: 1080 × 1080 pixels (1:1 square).
• Format: Export as a PDF (up to 100 MB max file size).
• Design Considerations: Leave roughly 10% margins around all edges. On mobile devices, LinkedIn overlays slide counters and navigation arrows along the bottom and top corners, which can obscure critical text.

3. LinkedIn Native Video Specifications

Video consumption on LinkedIn continues to shift toward short-form, mobile-first vertical formats.

• Vertical Video (1080 × 1920 px | 9:16 Aspect Ratio): Standard portrait format for mobile-first clip posts.
• Landscape Video (1920 × 1080 px | 16:9 Aspect Ratio): Standard horizontal video format, ideal for webinars, product demos, or interviews.
• Square Video (1080 × 1080 px | 1:1 Aspect Ratio): A versatile format that renders well across all devices.
• Technical Limits:
  • Duration: 3 seconds to 10 minutes.
  • Maximum File Size: 5 GB.
  • Supported Formats: MP4, MOV, AAC audio codec.

4. Banners, Profiles, & Articles

Beyond standard feed updates, brand presence on LinkedIn depends heavily on profile visuals and long-form headers.

Personal Profiles vs. Company Pages

• Personal Profile Photo: 400 × 400 px (1:1 ratio, circular crop).
• Personal Cover Banner: 1584 × 396 px (4:1 ratio).
• Company Logo: 400 × 400 px.
• Company Cover Banner: 1128 × 191 px (approx. 6:1 ratio).

Long-Form Articles & Newsletters

• Article Header Image: 1200 × 644 px (1.86:1 ratio).
• Newsletter Cover Image: 1280 × 720 px (16:9 ratio).

Visual Optimization Rules for LinkedIn

To ensure post assets look crisp and load quickly:

1. Use PNG for Text Heavy Graphics: JPG compression often creates blurry artifacts around typography and sharp vectors. Use PNG-24 for infographics, text quotes, and carousel slides.
2. Export at 2x Scale: For square graphics intended to display at 1080 px, design at 2160 × 2160 px. LinkedIn compresses uploaded files, and higher pixel density helps preserve sharpness on high-DPI (Retina) displays.
3. Respect Mobile Safe Zones: Keep vital elements—such as logos, callouts, and headline copy—centered. Mobile operating systems and the LinkedIn app UI overlay buttons, timestamps, and navigation cues around the outer edges of feed items.
