The Ultimate Guide to LinkedIn Post Image Sizes

When you scroll through your LinkedIn feed, some posts instantly catch your eye, while others look pixelated, awkwardly cropped, or downright messy. Often, the difference between a high-performing post and one that gets ignored isn’t just the writing—it’s the image dimensions.

Using the correct image size ensures your visuals look crisp, professional, and completely uncropped across both desktop and mobile devices.

📐 The Core LinkedIn Post Image Sizes

Depending on how you want to present your content, LinkedIn supports three primary image aspect ratios for standard feed posts:

| Format | Recommended Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Landscape | 1200 x 627 pixels | 1.91:1 | Link previews, blog shares, wide landscape photography |
| Square | 1080 x 1080 pixels | 1:1 | Infographics, quote graphics, product snapshots, flexible layouts |
| Portrait | 1080 x 1350 pixels | 4:5 | Maximizing mobile screen space and boosting engagement |

🔍 Choosing the Right Format for Your Goal

1. Landscape (1200 x 627 px) — The Classic Link Preview

This wide, horizontal format is LinkedIn’s traditional standard. It is most commonly seen when you drop a URL into a post and LinkedIn automatically generates a preview thumbnail.

• Pros: Great for external website links, news articles, and cinematic landscape photography.
• Cons: Because it takes up less vertical space, it can easily get lost on mobile screens where users scroll quickly.

2. Square (1080 x 1080 px) — The Safe All-Rounder

If you aren’t sure what layout to use, a square image is your safest bet. It displays cleanly and consistently whether someone views your post on a giant desktop monitor or a compact smartphone.

• Pros: Balanced look; ideal for charts, graphics, and simple product photos.
• Cons: Doesn’t capture as much feed real estate as a portrait image.

3. Portrait (1080 x 1350 px) — The Engagement Magnet

Because the majority of LinkedIn users browse on their phones, vertical content reigns supreme. A 4:5 portrait image stretches down the screen, forcing people to slow down their scroll to look at it.

• Pros: Dominates mobile feeds, leading to higher visibility and better engagement rates.
• Cons: Can look slightly oversized if viewed on certain desktop layouts, though LinkedIn handles it gracefully with letterboxing.

📑 Special Formats: Carousels and Documents

If you like uploading swipeable document carousels (PDFs) to share step-by-step guides or multi-page breakdowns, stick to these dimensions for each individual slide:

• Square Slides: 1080 x 1080 pixels (1:1 ratio)
• Portrait Slides: 1080 x 1350 pixels (4:5 ratio)

Square and portrait document carousels prevent text clipping and ensure that readers don’t have to pinch or zoom to read your text.

💡 Quick Technical Rules of Thumb

• File Size: Keep your image files under 5 MB.
• File Formats: Stick to JPEG/JPG for photos (smaller file size, rich colors) and PNG for text-heavy graphics, logos, or solid illustrations.
• Resolution: Always design at a higher resolution (at least 1080 pixels wide) so your graphics don’t pixelate when compressed by LinkedIn’s servers.
