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

You’ve spent hours crafting a thought-provoking post, designing a slick graphic, or clipping a standout video snippet. You hit publish, feeling confident. But when you check the live feed on your phone, disaster strikes: key text is cut off in a weird spot, your gorgeous photo looks awkwardly zoomed in, and your brand logo is half-hidden behind a system interface.

Why does this happen? The culprit is simple: incorrect dimensions.

LinkedIn is notorious for auto-cropping images that don’t fit its preferred containers. Because more than 60% of professionals view LinkedIn on mobile devices, visual standards matter more than ever. If your content looks pixelated or poorly cropped, users will scroll right past it.

Mastering LinkedIn post dimensions doesn’t have to be a guessing game. Here is everything you need to know to optimize your visuals, boost engagement, and make your brand look world-class.

1. Single Image Feed Posts (The Core Formats)

When sharing a standalone image, you have three primary layout options. Choosing the right one depends entirely on how you want your audience to interact with your content.

• Square (1:1 Aspect Ratio) — Recommended: 1200 x 1200 pixels (or 1080 x 1080 pixels)
  • Best for: General updates, quote cards, infographics, and clean, balanced branding.
  • Why use it: Square is the ultimate “safe bet.” It renders consistently across desktop and mobile feeds without unexpected cropping surprises.
• Portrait / Vertical (4:5 Aspect Ratio) — Recommended: 1080 x 1350 pixels
  • Best for: High-engagement mobile optimization.
  • Why use it: Vertical images take up significantly more physical space on a smartphone screen. More screen presence means higher visibility, longer pause-time, and ultimately better engagement rates.
• Landscape / Horizontal (1.91:1 Aspect Ratio) — Recommended: 1200 x 627 pixels (or 1200 x 628 pixels)
  • Best for: Landscape photography, event photos, and automated link previews.
  • Why use it: While great for traditional wide-angle shots, landscape photos take up the least vertical space on mobile feeds, making them easier for users to scroll past quickly.

2. Carousel & Document Posts (PDFs)

LinkedIn carousels (created by uploading multi-page PDF documents) are one of the most powerful organic reach tools on the platform. Because users have to swipe through to read, it drastically increases dwell time—a key metric the LinkedIn algorithm loves.

• Recommended Dimensions: 1080 x 1080 pixels (Square, 1:1) or 1080 x 1350 pixels (Portrait, 4:5)
• File Format: PDF, PPTX, or DOCX (PDF is preferred to lock in styling)
• Max File Size: 100 MB total
• Pro Tip: Keep your text legible by using at least a 24pt font size, and leave a clean margin around the edges so the platform’s navigation arrows don’t cover your text.

3. Video Specifications

Native video continues to dominate professional feeds, outperforming external links by a wide margin.

• Landscape Video (16:9): 1920 x 1080 pixels
• Square Video (1:1): 1080 x 1080 pixels
• Vertical Video (9:16): 1080 x 1920 pixels (Ideal for mobile-first storytelling)
• Max File Size: Up to 5 GB
• Duration: 3 seconds to 10 minutes (though keeping videos punchy under 60–90 seconds yields the highest completion rates).
• Golden Rule: LinkedIn auto-plays videos on mute. Always burn captions or add text overlays to your videos; otherwise, you will lose the vast majority of viewers who watch with the sound off.

4. Profile and Company Page Assets

Your personal profile and company page act as your digital landing page. Blurry or misaligned graphics instantly cheapen your professional credibility.

• Personal Profile Picture: 400 x 400 pixels (1:1 ratio, displayed inside a circular crop—keep your face dead-center)
• Personal Cover / Banner Photo: 1584 x 396 pixels (4:1 ratio)
• Company Logo: 300 x 300 pixels (Transparent PNGs work best)
• Company Page Cover Photo: 1128 x 191 pixels (Always preview on both desktop and mobile, as responsive design shifts the horizontal edges)

Summary Checklist for Cleaner Design

Before you hit schedule or post, run through this quick optimization checklist:

1. Choose the right format: Default to 1200 x 1200 (Square) for flexibility or 1080 x 1350 (Portrait) for maximum mobile impact.
2. Select the correct file type: Use PNG for graphics, charts, and text-heavy cards to prevent compression blur; use JPG for standard photographs.
3. Watch the file size: Keep images under 5 MB and ensure videos are optimized to avoid upload errors.
4. Mind the margins: Keep core text and important branding elements centered. Avoid placing crucial details right on the outer edges where cropping is prone to happen.

By aligning your content with these exact dimensions, you ensure your message is delivered cleanly, professionally, and without awkward formatting interruptions.
