LinkedIn Post Dimensions: Complete Reference Guide

Understanding LinkedIn Post Dimensions: Why Size Matters

Getting your LinkedIn content dimensions right isn't just about following technical rules—it’s about making a strong professional impression. When your images are pixelated, videos don't load properly, or carousels appear unprofessional, you are doing more than missing out on engagement. You risk harming your brand's credibility on a platform built for professional networking, where every detail contributes to your reputation.

The Connection Between Size and Success

Properly sized visuals are key to stopping the scroll. A post formatted correctly is more likely to be favored by the LinkedIn algorithm, which can lead to better reach. For example, posts with custom images receive 2x higher comment rates. This precision ensures your message is delivered clearly, without awkward cropping or a loss in quality, directly influencing how your audience sees your professionalism.

Why It's Crucial for Your Brand

The importance of using correct LinkedIn post dimensions is clear when you consider the platform's large user base of over 900 million members worldwide. In this busy feed, businesses that get these specifications right often stand out. When visuals are correctly sized, they capture attention more effectively, which encourages likes, comments, and shares that help build stronger professional connections. You can learn more about how LinkedIn post sizes affect engagement.

Single Image Posts: Perfect Dimensions and Best Practices

A single image post is a foundational piece of visual communication on LinkedIn. It's a direct and effective way to grab attention in a crowded professional feed. While LinkedIn supports various image sizes, using the correct LinkedIn post dimensions is crucial for ensuring your content appears professional and isn't awkwardly cropped on different devices, from desktop to mobile.

Recommended Dimensions and File Specifications

For the best results, the ideal dimension for a single image is 1200 x 627 pixels. This size corresponds to a 1.91:1 aspect ratio and is specifically designed to fit neatly within the feed's layout. It's also important to keep your file size in check; images should not exceed 5MB. A smaller file size ensures quick loading times, which is vital for stopping a user's scroll and making an impact. You can learn more about these requirements by exploring the official LinkedIn image guidelines on sendible.com.

To help you choose the right format, the table below provides a quick reference for LinkedIn's image post requirements.

LinkedIn Image Post Dimension Requirements

Format Type	Dimensions (pixels)	Maximum File Size	Best Use Case	Aspect Ratio
Single Image (Recommended)	1200 x 627	5MB	Standard image posts, announcements, and sharing links.	1.91:1
Square Image	1080 x 1080	5MB	Mobile-first content, infographics, and bold statements.	1:1
Vertical Image	1080 x 1350	5MB	Showcasing detailed visuals, infographics, or mobile-optimized content.	4:5

This table shows the recommended landscape format alongside square and vertical options, giving you the flexibility to choose the best format for your specific content goals.

The infographic below illustrates how the dimensions for a single image post compare to other common visuals on LinkedIn, such as company page banners and link thumbnails.

As the chart demonstrates, single images and link thumbnails share almost identical landscape dimensions. This consistency helps create a uniform visual experience when you share content.

Strategic Use of Image Formats

While the standard 1200 x 627 pixels is a safe bet, don't overlook other formats. Square images with a 1:1 aspect ratio (e.g., 1080 x 1080 pixels) often perform very well, especially on mobile devices where they take up more screen space. Vertical images with a 4:5 aspect ratio (e.g., 1080 x 1350 pixels) are also excellent for showcasing longer infographics or detailed visuals.

Experimenting with different formats can significantly impact your engagement. If you're looking for creative ways to apply these sizes, our guide on 10 social media post ideas for businesses offers practical examples of how various formats can be used to achieve different objectives.

Video Post Specifications: Formats, Sizes, and Technical Requirements

Video content on LinkedIn requires careful attention to detail to achieve professional results that properly represent your brand. Getting the technical specifics right is the first step toward creating videos that engage, rather than frustrate, your audience. Following these guidelines helps prevent common playback issues and poor visual quality.

Core Video Requirements

To ensure your video displays correctly, it's best to size it at 1080 x 1080 pixels for a square format or 1920 x 1080 pixels for a landscape orientation. LinkedIn recommends a minimum resolution of 720p to maintain clarity. The platform allows a maximum file size of 5GB, giving you plenty of room for high-quality uploads.

A key difference to remember is the duration limit. You can upload videos up to 15 minutes long from a desktop computer, but the limit is shorter at 10 minutes when uploading from the mobile app. For more detailed specifications, you can find additional information about LinkedIn video sizes on sendible.com.

File Formats and Compression

LinkedIn supports a variety of common video file formats, which ensures compatibility with most video editing software.

• Supported Formats: ASF, FLV, MPEG-1, MPEG-4, MKV, WebM, H264/AVC, MP4, VP8, VP9, WMV2, and WMV3.
• Unsupported: Certain formats like AVI, QuickTime, and MOV may need to be converted to a supported format before you can upload them.

Balancing file size with video quality is important for a good user experience. To make sure your videos are set up for success on LinkedIn and other social platforms, it's helpful to review a guide to effective video compression for social media. This will help you keep your visuals sharp without creating large files that load slowly in the feed.

Carousel Posts and Multi-Image Content: Advanced Formatting Guide

Carousel posts offer a way to tell a deeper story, effectively turning a single LinkedIn post into a multi-slide presentation. You can guide your audience through a detailed narrative, a step-by-step process, or a collection of related insights, all within one post.

For the best viewing experience, the recommended LinkedIn post dimensions for carousel slides are either square at 1080 x 1080 pixels or a taller vertical orientation at 1080 x 1350 pixels. It is vital to maintain a single, consistent size for all slides in your carousel. This ensures a seamless transition as users swipe from one slide to the next.

Design and Flow for Maximum Impact

A successful carousel is much more than a random assortment of images; it is a carefully structured journey for the viewer. Think of it as a mini-presentation designed to capture and hold attention.

• Strategic Structure: Your first slide is your hook. It must be compelling and clearly communicate the value of swiping through the rest of the content.
• Visual Consistency: Uphold your brand identity across every slide. This means using the same fonts, color scheme, and logo placement to create a professional and recognizable look.
• Narrative Progression: Each slide should logically follow the previous one. Whether you are telling a story or explaining a complex topic, break it down into easy-to-follow, digestible parts.
• Clear Call-to-Action: The final slide should prompt a specific action. You can ask a question to spark conversation, or guide users to find a link in the comments for more information.

For example, a marketing agency could use a carousel to showcase a project case study. The first slide might present the client's challenge, subsequent slides could detail the strategy and execution, and the final slides could display the successful results, ending with a call-to-action to "Learn more about our services."

Profile and Company Page Visual Specifications

Your LinkedIn profile and company page visuals act as your digital handshake. They form the first impression for every professional interaction on the platform. Following the correct dimension guidelines is essential for establishing credibility and strong brand recognition. Think of these specifications not just as technical requirements, but as strategic assets that build your professional presence.

Personal Profile and Company Page Banners

The banner image is valuable visual real estate. For both personal profiles and company pages, the recommended size is 1584 x 396 pixels. This wide format, a 4:1 aspect ratio, needs careful planning. Your profile photo often covers parts of the banner, especially on mobile devices. To ensure visibility across all screens, place important information like logos or text toward the center-right.

A well-designed banner can make a significant difference. Data indicates that profiles with strong banner and profile images can see an increase in views by up to 30%. You can discover more insights about optimizing LinkedIn banners on lemlist.com to make the most of this space.

Profile Photos and Company Logos

Consistency is key to branding, and that starts with your core visuals. A professional profile photo should be at least 400 x 400 pixels. Similarly, a company logo requires a 400 x 400 pixel dimension.

LinkedIn displays these square images as circles across the site, so it's important to center your image correctly to prevent awkward cropping. Using high-quality, properly sized images creates a polished and trustworthy brand identity. These visuals set a professional tone for every post you publish, which you can manage more easily when you learn how to schedule social media posts.

Mobile Optimization and Cross-Device Compatibility

Optimizing your content for mobile devices is not just a good idea; it's a fundamental part of a successful LinkedIn strategy. This goes beyond simple responsive design. It involves understanding how different LinkedIn post dimensions appear across various screen sizes to deliver a consistent, professional experience for every user. Since your content will be seen on smartphones, tablets, and desktops, a mobile-first mindset is essential for maintaining quality and engagement.

Designing for the Mobile Feed

The way your audience interacts with content on a smartphone is very different from on a desktop. Feeds are vertical, and screen real estate is at a premium. This is why certain formats, like square images, are often recommended for their wide compatibility. This is especially important considering that over 60% of LinkedIn traffic now comes from mobile devices. Each format, from square to landscape, serves different content goals and device optimization needs.

Testing Across Platforms

To ensure your content looks great everywhere, regular testing is a must. Before you publish, take a moment to preview your posts on different devices to check for common issues.

• Check for readability: Is the text on your images clear and easy to read without zooming in?
• Verify cropping: Does your main visual or video get awkwardly cut off on a vertical phone screen?
• Assess loading times: Will your high-resolution image or video load quickly for someone on a mobile data connection?

This quick quality check is a simple step that can prevent the brand damage that comes from unprofessional or poorly formatted posts.

Using it will help you steer clear of common upload errors and keep your content looking professional.

Actionable Implementation Checklist

Use this checklist to maintain high standards and prevent sizing mistakes before they happen. Building these steps into your process will save you time and improve how well your content performs.

• Verify Dimensions Before Uploading: Always confirm your image or video matches the recommended size for its format. For example, use 1200 x 627 pixels for images in shared link posts.
• Check File Size: Make sure your image is under 5MB and that videos are within LinkedIn's limits to prevent upload failures.
• Preview on Mobile: Before you hit "post," check how your content looks on a mobile device. This ensures that no important text or visual elements get cropped out on smaller screens.
• Maintain Aspect Ratio: For a clean and professional look, keep aspect ratios consistent across related visuals. For instance, all slides in a carousel post should use a 1:1 (square) ratio for a smooth scrolling experience.
