LinkedIn Post Size 2026: Image & Video Dimensions Guide

The best LinkedIn post image size is 1200 × 627 pixels with a 1.91:1 aspect ratio. This dimension displays perfectly on both desktop and mobile without cropping, ensuring your visual content looks professional across all devices.

Getting your dimensions right prevents awkward cropping, pixelation, and wasted effort on content that doesn't display correctly.

Key Takeaways

• Single image posts: 1200 × 627 pixels (1.91:1 landscape) or 1080 × 1080 (1:1 square)
• Portrait images: 1080 × 1350 pixels (4:5 ratio) take more feed space
• Carousel posts: 1080 × 1080 or 1080 × 1350 pixels per slide (PDF format)
• Video posts: 1920 × 1080 pixels (16:9) recommended, under 10 minutes
• File size limit: Keep images under 5-8MB for optimal loading

LinkedIn Image Post Sizes

According to LinkedIn's official specifications, images must meet specific requirements for optimal display.

Single Image Post Dimensions

File Requirements

• Supported formats: JPG, PNG, GIF
• Maximum file size: 5MB recommended (up to 36 megapixels technically supported)
• Minimum resolution: 552 × 289 pixels
• Color space: RGB

Why 1200 × 627 Works Best

The 1.91:1 landscape ratio is LinkedIn's default display format. When you upload this size:

• No automatic cropping occurs
• Images appear sharp on retina displays
• Content loads quickly on mobile
• Professional appearance is maintained

LinkedIn Carousel Post Dimensions

Carousels (document posts) have become LinkedIn's highest-engaging format. According to research from Metricool, carousels achieve 45.85% engagement rate—significantly higher than single images.

LinkedIn Live requires Creator Mode and approval. Apply through LinkedIn's Live application.

Mobile-First Optimization Tips

According to SocialPilot, over 60% of LinkedIn users browse on mobile. Optimize accordingly:

• Portrait (4:5) and vertical (9:16) formats take up more screen space on mobile, increasing engagement
• Keep important content centered—edges may be cropped differently on mobile vs desktop
• Use minimum 24pt font size for text overlays—smaller text is unreadable on phones
• Test on both devices before publishing—preview on mobile and desktop
• Compress files for faster loading on mobile networks (use TinyPNG)
• JPG for photos, PNG for text/logos—JPG compresses better for photos, PNG preserves text clarity

Portrait and Vertical: The Formats Winning in Q2 2026

LinkedIn's Q2 2026 feed update gives increased prominence to vertical and portrait content. Here's what the data shows:

Why Portrait (4:5) and Vertical (9:16) Are Growing

• More screen real estate: A 4:5 portrait image takes up approximately 65% more vertical feed space than a 1.91:1 landscape image on mobile
• Mobile-first users: With over 65% of LinkedIn traffic coming from mobile in 2026, portrait images stop the scroll more effectively
• Video shift: LinkedIn's feed now auto-plays vertical (9:16) videos in a TikTok-style viewer on mobile, giving them significantly more visibility than landscape videos
• Carousel impact: 4:5 portrait carousels get more swipes because each slide fills more of the screen

When to Use Each Format

Preparing for Future LinkedIn Image Changes

LinkedIn has been steadily shifting toward mobile-first, vertical-friendly formats. To future-proof your content:

• Save master files at the highest resolution your design tool supports — you can always scale down
• Create templates in both 1:1 and 4:5 so you can quickly adapt to format changes
• Monitor LinkedIn's creator updates at linkedin.com/creators for spec changes
• Test both formats and track which drives more engagement for your audience

Common LinkedIn Image Mistakes

1. Wrong Dimensions

Uploading images that don't match recommended ratios causes LinkedIn to crop important content. Always resize before uploading.

2. Low Resolution

Images under 1200 pixels wide appear blurry on retina displays. Use high-resolution source images.

3. Text in Crop Zones

Important text near image edges may be cropped differently on mobile vs desktop. Keep key content centered.

4. Oversized Files

Images over 5MB load slowly, hurting engagement. Compress before uploading using tools like TinyPNG.

Why the "Recommended" Photo Size Often Underperforms in 2026

LinkedIn's official documentation still lists 1200 × 627 as the recommended single-image size, and it remains technically correct—nothing breaks at that ratio. But "recommended" and "highest-engagement" are two different categories. The Q2 2026 feed weights vertical real estate more heavily than horizontal: a 1080 × 1350 portrait occupies roughly 2.15x the pixel footprint of a 1200 × 627 landscape on a mid-size phone screen, and that difference translates directly to dwell time. Dwell time, not impressions, is the variable the ranker uses to decide who else sees your post. The reason most guides still default to landscape is legacy thinking—LinkedIn used to be desktop-first, and 1200 × 627 was optimized for the right-rail feed of 2018. That layout no longer exists. Default to portrait unless you have a specific reason (link previews, ad placements with mandatory ratios) to use anything else.

The Hidden Cost of Mixing Aspect Ratios Across Posts

Profiles that rotate randomly between square, landscape, and portrait formats train the algorithm to treat their content as inconsistent, which dampens reach across all posts—not just the format that performed worst. A profile that commits to one primary aspect ratio (typically 4:5 portrait or 1:1 square) for at least 80% of its posts compounds reach faster because the algorithm builds a consistent dwell-time baseline for that creator. This pattern matters most for new accounts and accounts under 10,000 followers; established creators have enough signal density to absorb format variation.

Photo Size Mistakes That Pass Technical Checks but Lose Engagement

A post can meet every dimension spec LinkedIn publishes and still underperform. The most common failure is text-in-image at the wrong scale: legible on a 27-inch monitor while you design, illegible on a 6-inch screen where 80% of LinkedIn views happen. The fix is a hard rule—if your headline copy is under 36px in the source file at 1080 × 1350, redesign before you upload. The second failure is the "edge bleed" problem: important content placed within 60 pixels of any edge gets visually clipped on the feed because LinkedIn applies rounded corners and a subtle inset on mobile. Designers think in rectangles; LinkedIn's mobile feed renders in rounded squares. The third failure is contrast collapse on dark mode—dark gray text on a black background reads in your design tool, then disappears when half your audience views it through LinkedIn's dark theme. Test every image once in light mode and once in dark mode before publishing.

The Carousel-vs-Portrait Decision Frame Most Creators Get Wrong

The reflexive advice—"carousels get more engagement, so build carousels"—skips a step. Carousels reward swipe behavior, which means they punish posts where the value is front-loaded. If your strongest insight lives on slide 1, a carousel actively reduces reach because viewers stop after the first frame and the engagement signal stalls. The frame to use instead: choose carousel when your insight is sequential (steps, frameworks, before-and-after), choose portrait when your insight is singular (a stat, a quote, a chart). Forcing a carousel structure onto singular insights produces filler slides ("Here's why this matters") that train your audience to scroll past your future posts.

When to Break the 1080 × 1350 Default

Three scenarios justify deviation. Native video for thought-leadership content performs better at 1080 × 1920 (9:16) because it inherits the LinkedIn Video tab's vertical placement, which has its own discovery surface. Link-share posts to long-form content (newsletters, articles, podcasts) should use 1200 × 627 because LinkedIn's link unfurler crops anything else awkwardly and a clean unfurl meaningfully increases clickthrough. Sponsored content with a defined CTA—especially lead gen forms—often performs best at 1:1 square because square ads avoid the truncation that landscape ads suffer in the in-feed sponsored slot.

Frequently Asked Questions

What is the best image size for LinkedIn posts in 2026?

The best LinkedIn post image size is 1200 × 627 pixels with a 1.91:1 aspect ratio. This landscape format displays correctly across all devices without cropping. For more feed presence, use 1080 × 1350 pixels (4:5 portrait).

What size should LinkedIn carousel images be?

LinkedIn carousel slides should be 1080 × 1080 pixels (square) or 1080 × 1350 pixels (portrait). Upload as a PDF file with consistent dimensions across all slides. Maximum 100 pages per carousel.

Does LinkedIn compress images?

Yes, LinkedIn compresses uploaded images. To minimize quality loss, upload images as JPG or PNG under 5MB. Higher resolution source images (1200+ pixels wide) compress better and remain sharp after processing.

What's the LinkedIn video size limit?

LinkedIn accepts videos up to 5 GB in file size and 10 minutes in length. Recommended resolution is 1920 × 1080 pixels (1080p) in MP4 or MOV format. Videos under 90 seconds typically perform best for engagement.

How do I check if my LinkedIn image dimensions are correct?

Before uploading, check your image dimensions in any image editor. On Mac, right-click and select "Get Info." On Windows, right-click and select "Properties." Confirm the image matches LinkedIn's recommended 1200 × 627 pixels or your chosen format.

The Impact of LinkedIn's Algorithm on Image Dimensions

When it comes to LinkedIn post sizes, most marketers focus on the technical specifications, such as pixel dimensions and aspect ratios. However, what's often overlooked is the impact of LinkedIn's algorithm on how these images are displayed and engaged with. The algorithm prioritizes content that is likely to spark meaningful conversations and connections, which means that even if you're using the optimal image dimensions, your post may still not perform well if it's not relevant or engaging to your audience. For example, if you're posting a highly promotional image with little to no context, the algorithm may deprioritize it, regardless of its technical specifications. On the other hand, if you're posting a high-quality image with a compelling caption and relevant hashtags, the algorithm may give it more visibility, even if it's not perfectly optimized for dimensions. This highlights the importance of considering the algorithm's priorities when creating and optimizing your LinkedIn content.

Myth vs Reality: The "One-Size-Fits-All" Approach to LinkedIn Image Dimensions

There's a common misconception that there's a single, universal image dimension that works best for all LinkedIn posts. However, this "one-size-fits-all" approach is a myth that can lead to suboptimal results. The reality is that the best image dimension depends on the specific context and goals of your post. For example, if you're posting a carousel with multiple images, you may want to use a square format to create a consistent and cohesive look. On the other hand, if you're posting a single image with a lot of text overlay, a landscape format may be more effective. Additionally, different industries and audiences may respond better to different image dimensions and styles. For instance, a creative agency may use more experimental and avant-garde image dimensions to showcase their work, while a financial services company may stick to more traditional and conservative dimensions. By recognizing that there's no single "best" image dimension, you can tailor your approach to your specific needs and audience.

Advanced-Level: Using LinkedIn Image Dimensions to Create a Visual Hierarchy

For advanced marketers, creating a visual hierarchy is a crucial aspect of designing effective LinkedIn posts. A visual hierarchy refers to the way in which the eye is drawn to different elements within an image, and it can be used to guide the viewer's attention and create a clear narrative. By carefully selecting and optimizing your image dimensions, you can create a visual hierarchy that draws the viewer's eye to the most important elements of your post. For example, you can use a larger image dimension to create a prominent background element, and then use smaller dimensions for overlay text or graphics. You can also use different aspect ratios to create a sense of tension or balance, and to guide the viewer's eye through the image. By using image dimensions in this way, you can create a sophisticated and effective visual hierarchy that enhances the overall impact of your post.

The Role of Mobile Optimization in LinkedIn Image Dimensions

With the majority of LinkedIn users accessing the platform on mobile devices, mobile optimization is a critical consideration when it comes to image dimensions. However, mobile optimization is not just about using smaller image dimensions or compressing files to reduce load times. It's also about creating images that are specifically designed to be viewed on smaller screens, with clear and concise messaging, simple graphics, and a focus on the most important elements of your post. For example, you may want to use a square or portrait format to create a more immersive and engaging experience on mobile, or use images with a lot of negative space to create a clean and uncluttered look. Additionally, you should consider the different mobile devices and operating systems that your audience may be using, and optimize your images accordingly. By prioritizing mobile optimization, you can ensure that your LinkedIn posts look great and perform well across all devices.

Edge Cases: When Common Advice on LinkedIn Image Dimensions Backfires

While there are general best practices for LinkedIn image dimensions, there are also edge cases where common advice can backfire. For example, if you're posting a image with a lot of text overlay, using a large image dimension may actually make the text harder to read, rather than easier. Similarly, if you're posting a carousel with multiple images, using a consistent dimension throughout may create a sense of monotony, rather than visual interest. In these cases, it's often better to experiment with different image dimensions and formats to find what works best for your specific post and audience. Additionally, you should consider the cultural and linguistic nuances of your audience, as well as any specific brand or industry guidelines that may apply. By being aware of these edge cases and exceptions, you can avoid common pitfalls and create LinkedIn posts that are tailored to your unique needs and goals.

The Inverse Caption Rule: When Adding Visuals Means Writing Less

A pattern most creators get wrong: when you add a high-quality image, video, or carousel to a post, your caption should shrink, not expand. Posts that pair strong visuals with 200–500 character captions consistently outperform their long-caption counterparts because the image is doing the heavy lifting of communicating value, and a long caption competes with rather than complements the visual. The corollary is also true: text-only posts need the full 1,200–1,500 character range to earn the engagement that a visual would otherwise deliver. Auditing your own content: if your post has both a strong hero image and a 2,000-character caption, the algorithm and reader are forced to choose where to look, and engagement drops. Match the medium to the message — let visuals carry visual stories, and reserve long-form text for narrative or framework-style content.

The 30–60 Second Video Sweet Spot Most Creators Ignore

LinkedIn's 10-minute video maximum is misleading — the algorithm and audience attention curve favor a much narrower window of 30 seconds to 1 minute, with 90 seconds as an outer bound for content that genuinely requires depth. Videos in this range show meaningfully higher completion rates and feed retention than longer videos, even when the longer videos have higher production value. The mechanism is simple: LinkedIn's feed rewards completion, and a 45-second video with an 85% completion rate beats a 4-minute video with a 22% completion rate every time. For most B2B creators, this means cutting your video to the single sharpest insight, opening with a hook in the first 3 seconds (before captions auto-play), and trusting that the comments — not the video itself — are where the long-form conversation will happen. Save the 5-minute version for YouTube; LinkedIn rewards brevity in motion.

Portrait (1080 × 1350) Outperforms Square in 2026 — Here's Why

The conventional wisdom of "use 1080 × 1080 square images" is increasingly outdated. The 1080 × 1350 portrait (4:5) format now occupies meaningfully more vertical feed real estate on mobile — the device 70%+ of LinkedIn users browse on — which translates directly into more on-screen time per scroll, more dwell time, and a stronger engagement signal to the algorithm. Square images render at the same width but use 25% less vertical space, meaning they're scrolled past faster on average. The catch: portrait images require design discipline. Whitespace at top and bottom can feel empty if not used intentionally, and text overlays must be sized for mobile-first reading. The fix is to design your portrait posts so the focal element sits in the middle third, with branding or CTAs in the bottom safe zone where they won't be cut off by the "See more" interaction.

Carousel Slide Count Is Its Own Lever — and Most Creators Set It Wrong

The number of slides in a carousel materially affects performance independent of any individual slide's design. The 6–10 slide range consistently performs best: under 6 slides, completion is high but dwell time is too short to register as deep engagement; over 10 slides, completion drops sharply and the algorithm interprets early swipe-aways as a weak signal. The slide count also dictates per-slide text density — for 6–10 slides, aim for 25–50 words per slide so each one feels substantive without becoming a wall of text. Creators who treat carousels as "however many slides my idea needs" are leaving performance on the table; treating slide count as a constraint, and editing aggressively to fit 6–10 slides, almost always produces tighter, better-performing content.
