The Ultimate Guide to LinkedIn Post Image Sizes in 2026

When scrolling through your LinkedIn feed, what catches your eye first? Is it a wall of dense text, or a striking, perfectly framed visual that stops your thumb in its tracks?

In a professional network crowded with thoughts, insights, and announcements, visuals are your secret weapon. But there is nothing quite as jarring as a stunning graphic with its head chopped off, text cut off at the margins, or a blurry, pixelated preview.

LinkedIn’s display algorithms and UI updates constantly, meaning image dimensions matter more than ever. To help you maximize your engagement, look professional, and make every pixel count, here is the complete, definitive guide to LinkedIn post image sizes for 2026.

Why Image Size Matters on LinkedIn

Before diving into the numbers, it’s worth understanding why getting your dimensions right is crucial:

1. First Impressions: Your content represents your personal brand or your company. Crisp, properly formatted images signal professionalism and attention to detail.
2. Algorithm Favorability: LinkedIn prioritizes user experience. Images that render cleanly without awkward cropping encourage longer dwell time, which signals to the algorithm to push your post to a wider audience.
3. Multi-Device Compatibility: Your audience is viewing LinkedIn across desktop monitors, tablets, and a massive variety of mobile phone screens. Responsive dimensions ensure your image looks great everywhere.

LinkedIn Image Size Cheat Sheet (2026)

Here are the optimal dimensions for every type of image post on LinkedIn:

1. Standard Single Image Posts (Landscape & Square)

When you share a single photo or graphic directly into the feed, you have two primary options that perform exceptionally well:

• Landscape Image: 1200 x 627 pixels (1.91:1 ratio)
• Square Image: 1200 x 1200 pixels (1:1 ratio)

Pro-Tip: While landscape fills more horizontal space on desktop, square images (1200 x 1200 px) dominate mobile screens, taking up significantly more vertical real estate as users scroll. If your audience is primarily mobile-first, square is often the safest bet.

2. Vertical / Portrait Posts (The Engagement Winner)

If you want to maximize screen real estate and capture maximum attention in the feed, vertical imagery is your best friend.

• Vertical Image: 1080 x 1350 pixels (4:5 ratio)

This is the exact same aspect ratio popularized by Instagram and Facebook for high-impact portrait posts. It pushes the boundaries of how much vertical space your post occupies without getting awkwardly cropped by LinkedIn’s preview window.

3. Document / Carousel Posts (PDFs)

Document uploads (which render as swipeable carousels) are one of the highest-performing content formats on LinkedIn for thought leadership, tutorials, and step-by-step guides.

• Recommended PDF Page Size: 1080 x 1080 pixels (Square) or 1080 x 1350 pixels (Portrait)
• File Format: PDF

When designing carousels, keep your text size readable (at least 16–24pt equivalent in your design tool) and avoid cluttering the edges of the canvas so nothing gets obscured by UI navigation arrows.

4. Link Preview Images

When you paste a URL into a LinkedIn post, the platform automatically generates a thumbnail preview based on the website’s Open Graph (OG) image tag.

• Link Preview Image: 1200 x 627 pixels

Pro-Tip: Always check your link preview before publishing. If the image looks cropped or blurry, upload a custom image directly to the post alongside your link, or ensure your website’s meta tags are optimized.

5. Profile & Company Page Assets (Bonus)

While not “feed posts,” keeping your profile visuals sharp ties your entire content strategy together:

• Personal Profile Picture: 400 x 400 pixels (minimum)
• Personal Background Banner: 1584 x 396 pixels
• Company Page Logo: 300 x 300 pixels
• Company Page Cover Image: 1128 x 191 pixels

Best Practices for Designing LinkedIn Visuals

Knowing the dimensions is only half the battle. To ensure your posts actually convert views into engagement, keep these design rules in mind:

• Design for the “Safe Zone”: Keep important elements—like text, logos, and focal points—centered or well within the margins. Avoid placing crucial text right at the absolute edges where mobile UI elements or cropping might cut them off.
• High Contrast and Legibility: Many users browse LinkedIn in Dark Mode or on smaller screens outdoors. Use high-contrast color palettes and clean, sans-serif fonts so your text is legible in a fraction of a second.
• Less Text, More Impact: Images should complement your caption, not duplicate a wall of text. Use bold headlines, striking charts, or emotive photography that entices people to stop scrolling and read your accompanying text.
• Stick to Supported Formats: Stick to PNG for graphics with crisp lines and text, and JPEG for photographs to keep file sizes optimized and prevent compression artifacts.
