The Ultimate Guide to LinkedIn Post Image Sizes: Dimensions, Specs, and Best Practices

When you spend hours crafting a thought-provoking LinkedIn post, the last thing you want is for your accompanying image to look pixelated, cut off, or awkwardly stretched. On a professional network driven by visual first impressions, image dimensions matter.

Because LinkedIn dynamically handles images across desktop browsers and mobile apps, uploading just any image won’t cut it. To stop the scroll, maximize your screen real estate, and keep your personal brand or company page looking sharp, you need to use the exact right dimensions.

Breaking Down the Three Core Feed Image Formats

Not all image orientations are created equal. Depending on the narrative style of your post, you should select the format that strategically fits your goal.

1. The Portrait Image (1080 × 1350 px) — The Scroll-Stopper

• Aspect Ratio: 4:5
• Why use it: Portrait is the undisputed champion for organic engagement on LinkedIn. It is the tallest format LinkedIn will display in the mobile feed without forcefully cropping or clamping the top and bottom. Because it occupies the most vertical pixels on a phone screen, users are forced to interact with it longer.
• Best for: Deep-dive infographics, educational graphics, frameworks, and text-heavy summaries.

2. The Square Image (1080 × 1080 px) — The Versatile All-Rounder

• Aspect Ratio: 1:1
• Why use it: Square images look clean, modern, and symmetrical. They render exceptionally well whether someone is viewing your post on a desktop monitor, tablet, or smartphone. They are also the gold standard if you plan to cross-post the exact same graphic to Instagram or Facebook.
• Best for: Single quote cards, product shots, clean data charts, and multi-image posts.

3. Landscape Image / Link Previews (1200 × 627 px) — The Professional Standard

• Aspect Ratio: 1.91:1
• Why use it: This is LinkedIn’s native default landscape shape. It is most frequently seen when you share an external URL and LinkedIn automatically generates a link preview card. If your image isn’t built to this ratio, LinkedIn will automatically letterbox it with white/gray margins or awkwardly crop the sides.
• Best for: Sharing blog posts, news articles, press releases, or traditional landscape photography.

Golden Rules for Perfect LinkedIn Images

Knowing the pixel dimensions is only half the battle. To ensure your creative assets look professional, keep these technical and design guardrails in mind:

• Watch the File Size: LinkedIn caps standard image uploads at 5MB to 10MB. If your file is too large, compression tools or upload errors can ruin your flow. Aim to compress your JPEGs and PNGs without losing crispness.
• Stick to Safe Formats: Stick to JPG, PNG, or GIF for standard images. Avoid formats like WebP or HEIC unless you are strictly operating from a specific device ecosystem, as cross-platform compatibility can occasionally trigger upload bugs.
• Design for Mobile First: Over 60% of LinkedIn traffic happens on mobile devices. If you include text inside your graphics, ensure the font size is large enough to read easily on a small screen, and keep critical text clustered toward the center to protect it from edge distortions.
• Consistency in Multi-Image Posts: If you are uploading a grid of multiple photos, ensure they all share the exact same aspect ratio (
