Use 1200x627 for landscape images, 1080x1080 for square and carousel slides, 1080x1350 for portrait, 1584x396 for banners, and keep all files under 5MB to ensure LinkedIn visuals render cleanly on every device.

Getting your LinkedIn visuals sized correctly goes far beyond following a spec sheet. It directly affects how professional your brand appears. Pixelated images, improperly loaded videos, and awkwardly cropped carousels can undermine credibility on a platform where professional perception is everything.

LinkedIn regularly adjusts its feed layout and rendering behavior, so staying current with linkedin post sizes 2026 is essential for keeping your visuals sharp and well-optimized across both desktop and mobile.

How Proper Sizing Drives Better Results

Correctly sized visuals stop people mid-scroll. Posts that render cleanly are more likely to receive favorable treatment from the LinkedIn algorithm, which can amplify your reach. Precise formatting also ensures your message comes through without awkward cropping or quality loss. Research shows that posts featuring custom-sized images can receive up to twice the comment rate of those with default or poorly formatted graphics.

Why Dimensions Matter for Brand Perception

With over 900 million LinkedIn members, brands that follow correct specifications gain a measurable edge in attention and engagement. Well-formatted visuals catch the eye more effectively, which translates into stronger professional connections and deeper audience interaction.

Single Image Posts: Sizes, Ratios, and Tips

The single image post remains a cornerstone of LinkedIn visual content. Using the right linkedin post dimensions ensures your content displays professionally and avoids unwanted cropping on any device.

Specifications and File Requirements

The standard recommendation is 1200 x 627 pixels at a 1.91:1 aspect ratio. Keep file sizes under 5MB to ensure fast loading.

Dimension Reference Table

Format Type Dimensions (pixels) Maximum File Size Best Use Case Aspect Ratio

Standard Landscape 1200 x 627 5MB Link shares, announcements, general image posts 1.91:1

Square 1080 x 1080 5MB Mobile-optimized content, infographics, bold statements 1:1

Vertical / Portrait 1080 x 1350 5MB Detailed visuals, tall infographics, mobile-first designs 4:5

The landscape format is the default recommendation, but square and vertical options each have strategic advantages depending on your content goals.

Notably, single image posts and link preview thumbnails share nearly identical landscape dimensions, which creates a consistent visual experience when sharing content with URLs.

Choosing the Right Format Strategically

Square images tend to perform well on mobile because they occupy more screen real estate. Vertical images are ideal for detailed graphics and infographics that benefit from extra height. Experimenting with different formats and measuring engagement can reveal which shape resonates most with your specific audience.

When you share a URL, LinkedIn auto-generates a thumbnail preview. To control how this preview appears, set your website's Open Graph image to 1200 x 627 pixels. This prevents poor cropping and improves click-through rates for articles, blog posts, and landing pages.

Core Specifications

Use 1080 x 1080 pixels for square video or 1920 x 1080 pixels for landscape. LinkedIn recommends a minimum resolution of 720p. The maximum file size is 5GB.

Desktop uploads can be up to 15 minutes long, while mobile uploads are capped at 10 minutes.

Supported File Types and Compression Notes

Accepted formats include ASF, FLV, MPEG-1, MPEG-4, MKV, WebM, H264/AVC, MP4, VP8, VP9, WMV2, and WMV3.

Formats such as AVI, QuickTime, and MOV may require conversion before uploading.

Striking the right balance between file size and visual quality is important to avoid slow load times that cause viewers to scroll past.

Protecting Text and Logos in the Safe Zone

Even with correct overall dimensions, LinkedIn may clip the edges of your visuals. To safeguard essential elements such as text, logos, and CTAs, keep them within the center 80 percent of the canvas. This buffer prevents accidental cropping on mobile screens and ensures your core message remains visible.

Carousel posts turn a single LinkedIn post into a swipeable, multi-slide presentation. The recommended slide dimensions are 1080 x 1080 or 1080 x 1350, and every slide must use the same size for a cohesive look.

Structuring Slides for Maximum Impact

A successful carousel is not just a collection of random images. It is a deliberate narrative designed to hold attention from the first swipe to the last.

  • Hook With the First Slide: The opening slide must be visually arresting and clearly communicate the value of swiping through the rest of the deck.

  • Maintain Visual Consistency: Use the same fonts, color palette, and logo placement across every slide to reinforce brand recognition.

  • Create a Logical Flow: Each slide should connect naturally to the one before it. Break complex topics into digestible, sequential steps.

  • End With a Call to Action: The final slide should prompt the viewer to take a specific step, whether that is commenting, visiting a link, or sharing the post.

For example, an agency could use a carousel to walk through a client case study: the opening slide introduces the challenge, the middle slides detail the strategy and execution, and the closing slides present results alongside a CTA to learn more.

Document Posts: PDFs, Guides, and Whitepapers

Document posts are among LinkedIn's highest-performing content types. For PDF uploads, use 1080 x 1080 pixels per page or a vertical 4:5 ratio. LinkedIn allows documents up to 100 pages and 100 MB. Design the first page like a book cover with a bold, attention-grabbing headline to maximize swipe-through rates.

Profile and Company Page Visual Specs

The visuals on your LinkedIn profile and company page function as your digital first impression. Following the correct dimension guidelines is critical for establishing credibility and reinforcing brand identity. Think of these specifications as strategic assets that strengthen your professional presence.

Keeping these visuals polished complements every post you publish and pairs well with using a reliable LinkedIn post scheduler to manage your content calendar.

Personal and Company Banners

The recommended banner size is 1584 x 396 pixels at a 4:1 ratio. Center important design elements because profile photos overlap parts of the banner, particularly on mobile.

Well-designed banners can increase profile views by as much as 30 percent.

Profile Photos and Logos

Use 400 x 400 pixels for a crisp, professional image. LinkedIn displays photos in a circular crop, so center faces and logos within the frame.

Event Cover Photo Dimensions

For LinkedIn Events, the recommended cover image is 1600 x 900 pixels at a 16:9 aspect ratio. Keep text and logos centered to avoid mobile cropping.

Article Header Image Dimensions

The optimal header image for long-form LinkedIn articles is 2000 x 600 pixels. This wide banner format creates a strong visual opening and improves click-through from the feed.

Designing for Mobile Users

More than 60 percent of LinkedIn traffic originates from mobile devices, making mobile optimization non-negotiable.

Tips for the Mobile Feed

Square images are generally the most versatile format for mobile viewing. Always verify readability, check for unintended cropping, and confirm that load times remain fast.

Cross-Device Testing

Preview every piece of content on multiple devices before publishing to confirm clarity and correct rendering. Consulting additional social media dimension references can help you fine-tune your approach further.

Accessibility: Alt Text and Captions

Add descriptive alt text to every image for improved accessibility and search engine visibility. For videos, always include captions since a large share of LinkedIn video content is watched without sound. These steps broaden your audience reach and improve the overall user experience.
