The Ultimate Guide to LinkedIn Post Dimensions (2026 Edition)

Whether you are building your personal brand, driving B2B leads, or managing a corporate enterprise page, LinkedIn has evolved far beyond a digital resume. Today, it is a dynamic visual platform where storytelling meets professional networking.

However, nothing kills professional credibility faster than a pixelated logo, a cropped-off infographic, or a banner image that cuts off right across your face. Because LinkedIn dynamically resizes and optimizes content across desktop and mobile devices, nailing your image and video sizes is crucial.

This comprehensive guide breaks down the exact, up-to-date dimensions for every type of LinkedIn post and asset to ensure your content always looks sharp, polished, and professional.

1. Standard Shared Images & Photos

When you upload a standalone photo or a graphic alongside your text update, you want it to command attention as users scroll through their feeds.

• Recommended Dimensions: 1200 x 627 pixels (or a 1.91:1 aspect ratio)
• Square Alternative: 1080 x 1080 pixels (1:1 aspect ratio)
• Supported Formats: JPEG, PNG, GIF
• Maximum File Size: 5 MB

Pro Tip: While horizontal images (1200 x 627) take up traditional desktop width, square images (1080 x 1080) take up more vertical real estate on mobile feeds, giving your post a higher chance of stopping the scroll.

2. LinkedIn Documents (Carousels & PDFs)

Document posts—commonly known as LinkedIn carousels—are one of the highest-performing content formats on the platform. They encourage swiping, which increases “dwell time” (how long a user spends on your post) and signals to the algorithm that your content is valuable.

• Square Carousel: 1080 x 1080 pixels (1:1 aspect ratio)
• Portrait Carousel: 1080 x 1350 pixels (4:5 aspect ratio — highly recommended for mobile readability)
• Supported Format: PDF only (each page acts as a slide)
• Maximum File Size: 100 MB (up to 300 pages, though 8 to 12 slides is the sweet spot)

Pro Tip: Design your carousels in portrait mode (1080 x 1350) using tools like Canva. This forces the document to occupy maximum space on smartphone screens. Always save and export as a standard PDF before uploading.

3. Link Previews with Images

When you share an external link (to a blog post, landing page, or news article), LinkedIn automatically generates a preview card based on the Open Graph metadata of that webpage.

• Recommended Image Size: 1200 x 627 pixels
• Aspect Ratio: 1.91:1

Pro Tip: If the automatically generated preview image looks cropped or low-resolution, make sure the destination website’s featured image matches the 1200 x 627 pixel specification. Alternatively, you can upload a native image and paste the link in the text body (though engagement metrics vary by format).

4. Video Posts

Video content continues to capture high engagement on professional feeds, whether you are sharing a quick thought leadership clip, a product demo, or a webinar snippet.

• Landscape Video: 1920 x 1080 pixels (16:9 aspect ratio)
• Square Video: 1080 x 1080 pixels (1:1 aspect ratio)
• Vertical Video: 1080 x 1350 pixels or 1080 x 1920 pixels (9:16 aspect ratio)
• Duration: 3 seconds to 10 minutes
• Maximum File Size: 5 GB
• Supported Formats: MP4, ASF, AVI, FLV, MOV, MKV, WebM

Pro Tip: Vertical and square videos perform exceptionally well because most professionals browse LinkedIn on mobile devices. Always burn captions into your videos, as many users watch feeds with the sound off by default.

5. Profile & Page Branding Assets

Your profile or company page is your digital storefront. First impressions matter immensely here.

Personal Profile

• Profile Picture: 400 x 400 pixels minimum (can be larger, keep it square 1:1; max file size 8 MB). Ensure your face is centered, as it gets cropped into a circle.
• Background Banner (Header): 1584 x 396 pixels (4:1 aspect ratio).

Company Pages

• Company Logo: 300 x 300 pixels (Square format; appears next to all your posts).
• Cover Image / Hero Image: 1128 x 191 pixels.

Note on Banners: Keep important text and branding elements away from the bottom-left corner of personal profile banners, as the circular profile picture overlaps that area on desktop view.
