Mastering LinkedIn Post Dimensions: The Ultimate Guide to Visual Specs

First impressions matter—especially in a professional feed packed with thought leadership, industry news, and networking updates. When you scroll through LinkedIn, what makes you stop? Odds are, it’s a striking image, a clean infographic, or a compelling video thumbnail.

However, there is nothing quite as jarring as a brilliant graphic that gets awkwardly cropped, awkwardly pixelated, or cut off mid-sentence. To build authority and make your content shine, you need to use the exact dimensions required by the platform.

Whether you are designing a single-image post, a multi-page document carousel, or setting up a personal profile banner, here is your complete guide to LinkedIn post dimensions and best practices for 2026.

1. Single Image Posts & Link Previews

Single images are the workhorses of LinkedIn content. They capture attention quickly and anchor your text updates.

• Recommended Size: 1200 x 627 pixels (Landscape) or 1200 x 1200 pixels (Square)
• Aspect Ratio: 1.91:1 (Landscape) or 1:1 (Square)
• Supported Formats: JPEG, PNG, GIF

Pro Tip: While horizontal images (1200 x 627) are great for link previews, square images (1200 x 1200) occupy more vertical real estate on mobile screens. Given that a significant majority of professionals browse LinkedIn on their phones, square images naturally command more attention as users scroll.

2. Document Posts & Carousels (PDFs)

Document carousels are currently one of the highest-performing content formats on LinkedIn. They invite swiping, keep readers engaged longer, and are fantastic for breaking down complex ideas, step-by-step guides, or case studies.

• Recommended Size: 1080 x 1080 pixels (Square) or 1080 x 1350 pixels (Vertical/Portrait)
• Aspect Ratio: 1:1 or 4:5
• File Format: PDF

Pro Tip: Design your carousels using vertical dimensions (1080 x 1350 px) if you want to maximize screen takeover on mobile devices. Always export your final slides as a high-quality PDF before uploading them directly via the document icon in the post composer.

3. LinkedIn Stories & Video Specs

Video content continues to expand its footprint on professional feeds, and getting your video dimensions right ensures your audience isn’t squinting at a tiny, letterboxed box.

• Standard Video Posts:
  • Landscape: 1920 x 1080 pixels (16:9 ratio)
  • Square: 1080 x 1080 pixels (1:1 ratio)
  • Vertical: 1080 x 1920 pixels (9:16 ratio)
  • File Size Limit: Up to 5 GB
  • Duration: 3 seconds to 10 minutes

Pro Tip: Vertical videos (9:16) mirror the native viewing experience of modern smartphones. If you are uploading clips from webinars, interviews, or quick tips, cropping them into a vertical format will dramatically boost completion rates.

4. Profile & Company Page Assets

Your visual identity extends far beyond your daily updates. Your profile and page headers act as your digital storefront.

• Profile Picture:
  • Dimensions: 400 x 400 pixels (minimum) up to 7680 x 4320 pixels.
  • Tip: Keep your face centered; LinkedIn automatically crops profile photos into a circle.
• Personal Background Banner:
  • Dimensions: 1584 x 396 pixels (4:1 ratio)
• Company Page Cover Image:
  • Dimensions: 1128 x 191 pixels

Pro Tip: For personal background banners, keep critical text or branding on the right-hand side. On desktop layouts, your profile picture overlaps the bottom-left corner of the banner, which can obscure important details if you aren’t careful.
