The Ultimate Guide to LinkedIn Post Image Sizes in 2026

When you are scrolling through your LinkedIn feed, what catches your eye first? Usually, it is not the text—it is the visual. Whether it is a striking infographic, a team milestone photo, or a sleek carousel, images are the hook that stops the scroll.

However, nothing kills a professional vibe faster than a pixelated, awkwardly cropped, or awkwardly stretched image. LinkedIn’s layout has specific preferences, and hitting those exact dimensions ensures your content looks polished, credible, and engaging.

This complete guide breaks down everything you need to know about LinkedIn post image sizes to make your brand look its absolute best.

Why Image Dimensions Matter on LinkedIn

LinkedIn is a professional network, and presentation is everything. When your image dimensions match LinkedIn’s native container requirements:

• No Awkward Cropping: Your entire message or focal point remains visible without getting cut off at the edges.
• Crisp Resolution: High-quality images signal attention to detail and professionalism.
• Higher Engagement: Posts with optimized visuals naturally draw more views, comments, and shares because they are easier and more enjoyable to consume.

The Cheat Sheet: LinkedIn Image Sizes at a Glance

Here is a quick reference table for the most common LinkedIn post types:

| Post Type | Recommended Dimensions (Pixels) | Ideal Aspect Ratio |
| :— | :— | :— |
| Standard Feed Post (Single Image / Square) | 1080 x 1080 | 1:1 |
| Portrait Feed Post (Vertical) | 1080 x 1350 | 4:5 |
| Landscape Feed Post (Horizontal) | 1200 x 627 | 1.91:1 |
| Link Preview Thumbnail | 1200 x 627 | 1.91:1 |
| Document / Carousel Post | 1080 x 1080 (or 1080 x 1350) | 1:1 or 4:5 |

Breaking Down the Best Formats for Your Strategy

1. The Square Post (1080 x 1080 px)

• Best for: General updates, quotes, product highlights, and multipurpose sharing.
• Why it works: Square images take up a comfortable amount of vertical space on both desktop and mobile feeds without dominating the entire screen. They are versatile and safe because they rarely suffer from unexpected mobile cropping.

2. The Portrait Post (1080 x 1350 px)

• Best for: Infographics, step-by-step guides, tall photography, and deep-dive visuals.
• Why it works: Vertical images are absolute real-estate winners on mobile devices. Because most people browse LinkedIn on their phones, a 4:5 aspect ratio takes up more of the screen, naturally forcing users to slow down their scroll as they take in your content.

3. The Landscape Post (1200 x 627 px)

• Best for: Wide photography, landscape imagery, and traditional banner-style graphics.
• Why it works: While landscape images take up less vertical space, they are fantastic for cinematic shots or standard graphics. However, keep your most important text and elements centered, as mobile feeds can sometimes compress the view.

4. Link Previews (1200 x 627 px)

• Best for: Sharing blog posts, news articles, or external landing pages.
• Why it works: When you drop a URL into a LinkedIn post, it automatically generates a preview card. Ensuring your website has an Open Graph (OG) image set to 1200 x 627 pixels guarantees that your link preview looks sharp and enticing rather than blurry or cropped off-center.

5. Document & Carousel Posts (1080 x 1080 or 1080 x 1350)

• Best for: Educational slide decks, step-by-step frameworks, and storytelling.
• Why it works: PDF documents uploaded as carousels are one of the highest-performing content formats on LinkedIn. Using a 1:1 square or 4:5 portrait layout for your slides ensures maximum readability across all devices.

Pro-Tips for Flawless LinkedIn Visuals

• Design for Mobile First: Over 60% of LinkedIn traffic comes from mobile devices. Always preview your graphics on a smaller screen to ensure text is large enough to read easily.
• Keep Text Minimal: Let your imagery do the heavy lifting. If you include text on your graphics, keep the font bold, clean, and concise. Avoid cluttering the corners where UI elements (like profile icons or expansion buttons) might overlap.
• Stick to Supported File Formats: Save your final designs as PNG for graphics with sharp lines and text, or JPEG for photographs to keep file sizes optimized. LinkedIn supports files up to 5MB.

By following these dimensions, you ensure your content looks intentional, professional, and primed for maximum engagement.
