The Ultimate Guide to LinkedIn Post Dimensions

Scrolling through LinkedIn, your visual content is your digital first impression. A blurry graphic, a awkwardly cropped banner, or an image cut off at the edges can instantly tank engagement before a reader even looks at your text. Because LinkedIn is heavily optimized for mobile devices, knowing the exact dimensions for your posts, carousels, and profile assets is essential for building a polished professional brand.

Quick Reference: LinkedIn Image & Video Dimensions

To keep your feed looking sharp and professional, use this quick-reference table for standard post formats:

| Post Format | Recommended Size (Pixels) | Aspect Ratio | Best For |
| :— | :— | :— | :— |
| Portrait Post | 1080 x 1350 px | 4:5 | Maximum mobile screen estate, infographics, storytelling |
| Square Post | 1080 x 1080 px | 1:1 | Clean graphics, product photos, standard quote cards |
| Landscape / Shared Image | 1200 x 627 px | 1.91:1 | Photos, link previews, event banners |
| Carousel (Document PDF) | 1080 x 1080 px or 1080 x 1350 px | 1:1 or 4:5 | Step-by-step guides, slide decks, multi-page deep dives |
| Video Post (Vertical) | 1080 x 1920 px | 9:16 | Reels-style thought leadership clips, short tutorials |

Deep Dive: Choosing the Right Format

1. The Power of Portrait (1080 x 1350 px)

If you want to stop the scroll, portrait is king. Because most professionals browse LinkedIn on their smartphones, a 4:5 aspect ratio takes up significantly more vertical real estate in the mobile feed than a square or landscape image. Use portrait dimensions for heavy infographics, step-by-step breakdowns, and long-form visual summaries.

2. Carousel & Document Posts

Carousels (created by uploading a multi-page PDF document) remain one of the highest-performing content formats on LinkedIn.

• Square (1080 x 1080 px): Works well across both desktop and mobile layouts symmetrically.
• Vertical (1080 x 1350 px): Delivers a taller, more immersive swiping experience on mobile devices.
• Pro Tip: Keep critical text and logos away from the very bottom edge of your slides, where LinkedIn’s native swipe pagination indicators appear.

3. Link Previews

When you share a blog post, newsletter, or external link, LinkedIn automatically generates a preview using an image pulled from the target page.

• The ideal size for link preview images is 1200 x 627 pixels.
• If your website’s Open Graph (OG) image doesn’t match this ratio, LinkedIn may crop or distort it, so it’s always smart to configure your site’s metadata properly.

Profile Branding Essentials

Beyond your daily feed posts, your personal or company profile acts as your landing page. Make sure these foundational assets are properly dimensioned:

• Personal Profile Picture: Minimum 400 x 400 pixels (JPEG, GIF, or PNG; max file size 8MB). Keep your face centered, as the platform crops profile images into a circle.
• Personal Background Banner: 1584 x 396 pixels (4:1 aspect ratio). Note that profile pictures slightly overlap the bottom-left corner of the banner on desktop view, so avoid putting important text or logos there.
• Company Page Logo: 300 x 300 pixels.
• Company Page Cover Banner: 1128 x 191 pixels.

Best Practices for Sharp Visuals

• Stick to PNG or high-quality JPEG: Avoid heavily compressed JPGs that introduce pixelation and artifacting around text elements.
• Watch your text hierarchy: Keep text sizes large enough to be easily readable on a small smartphone screen. If someone has to squint to read your graphic, they will keep scrolling.
• Mind the safe zones: Leave a comfortable margin around the borders of your graphics so your content never feels cramped or accidentally clipped by platform UI overlays.
