Master the Feed: The Ultimate Guide to LinkedIn Post Dimensions and Sizes

First impressions matter. In the fast-paced digital ecosystem of LinkedIn, where professionals scroll through endless feeds of insights, industry news, and updates, catching a user’s eye in milliseconds is everything. While your copy hooks them in, your visual asset is the anchor that stops their thumb mid-scroll.

However, nothing kills a professional aesthetic faster than a pixelated logo, a cropped-off infographic headline, or a banner that cuts off your face.

This comprehensive guide breaks down the exact LinkedIn post dimensions you need for images, videos, carousels, and profile branding to ensure your content always looks crisp, professional, and optimized for engagement.

1. Single Image Post Dimensions

When posting static images to your feed, you have three primary aspect ratio options. Choosing the right one depends heavily on your content and where your audience views it.

• Portrait (1080 × 1350 pixels | 4:5 Aspect Ratio): The Engagement Winner.
  With over 60% of LinkedIn traffic originating from mobile devices, vertical real estate is king. Portrait images take up the most vertical space on a phone screen, holding a reader’s attention longer. Best for: Text-heavy graphics, data charts, infographics, and storytelling visuals.
• Square (1080 × 1080 pixels | 1:1 Aspect Ratio): The Safe All-Rounder.
  Squares look neat, clean, and symmetrical on both desktop monitors and mobile feeds. They are versatile and work well if you plan to cross-post your visual assets to Instagram or X (formerly Twitter). Best for: Quote cards, single-idea graphics, and product shots.
• Landscape (1200 × 627 pixels | 1.91:1 Aspect Ratio): The Link Preview Standard.
  This is LinkedIn’s traditional horizontal format. While it works fine for wide photography, it leaves a lot of empty white space on mobile screens. Best for: Sharing external links, wide landscape photography, and formal company announcements.

Pro Tip: Always design your feed images with a minimum width of 1080 pixels. Going lower risks aggressive compression artifacts from LinkedIn’s renderer, making your text blurry. Keep crucial text elements well away from the outer edges to avoid awkward cropping across different viewports.

2. Carousel and Document Post Dimensions

LinkedIn document posts (often referred to as carousels or slide decks) are one of the platform’s highest-performing formats for organic reach and education. When you upload a multi-page PDF, LinkedIn renders it as a swipeable carousel.

• Recommended Dimensions:
  • Square Slides: 1080 × 1080 pixels (1:1 ratio)
  • Portrait Slides: 1080 × 1350 pixels (4:5 ratio) — highly recommended for maximum mobile presence
• File Specifications: Save your presentation or design as a PDF before uploading. Keep individual file sizes under 100MB, and ensure text contrast is high so it remains legible on dark-mode displays.

3. Video Post Dimensions

Video content continues to command high engagement on professional networks. Whether you are uploading native clips or video advertisements, keep these specs in mind:

• Square Video: 1080 × 1080 pixels (1:1 ratio)
• Landscape Video: 1920 × 1080 pixels (16:9 ratio)
• Portrait Video: 1080 × 1350 pixels (4:5 ratio) or full vertical 1080 × 1920 pixels
• Technical Limits: Aim for a 720p resolution or higher. LinkedIn supports MP4 files up to 5GB (though web uploads cap out at smaller sizes depending on desktop vs. mobile). Keep promotional or thought-leadership videos concise—shorter clips enjoy significantly higher completion rates.

4. Profile and Company Branding Dimensions

Your personal profile or company page is your digital landing page. If your banner or profile photo looks stretched or clipped, it undermines your authority before people even read your posts.

• Personal Profile Photo: 400 × 400 pixels (1:1 ratio). Keep your face dead-center, as LinkedIn crops profile pictures into a clean circle. Maximum file size is 3MB.
• Personal Background Banner: 1584 × 396 pixels (4:1 ratio). Crucial Warning: On mobile views, the LinkedIn mobile app aggressively crops the sides of your personal banner. Keep important text, logos, or contact info centered.
• Company Page Logo: 300 × 300 pixels.
• Company Page Cover Banner: 1128 × 191 pixels (roughly 5.9:1 ratio).

Final Thoughts

Formatting your assets correctly takes only a few extra seconds in graphic design tools like Canva, Figma, or Photoshop, but the payoff is immense. By designing natively for mobile dimensions (like 1080 × 1350 for posts and carousels), you maximize your visual footprint, respect your reader’s experience, and set your content up for peak professional engagement.
