The Complete Guide to LinkedIn Post Image Sizes: Stop the Scroll and Maximize Engagement

Let’s face it: we’ve all spent hours crafting the perfect professional text hook, pouring our expertise into a LinkedIn post, only to attach an image that gets awkwardly cropped, heavily pixelated, or totally ignored in the feed.

Visuals are no longer optional on LinkedIn—they are the ultimate mechanism for stopping the scroll. With over 60% of traffic coming from mobile devices, your image dimensions can make or break your reach. Uploading a random screenshot or the wrong aspect ratio means LinkedIn will automatically crop your masterpiece, cutting off text and ruining your layout.

This guide breaks down everything you need to know about LinkedIn post image sizes, formats, and best practices to ensure your content always looks sharp and drives engagement.

1. Standard Feed Post Image Sizes

When posting a single image to your feed, you have three primary layout options. Choosing the right one depends entirely on what you are sharing and where you want your viewer’s eyes to land.

| Format | Recommended Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Square | 1080 x 1080 px | 1:1 | Infographics, quote cards, safe all-rounder |
| Portrait / Vertical | 1080 x 1350 px | 4:5 | Mobile optimization, tall graphics, highest engagement |
| Landscape | 1200 x 627 px | 1.91:1 | Link previews, wide landscape photography, banners |

• Square (1080 x 1080 px): The safest, most versatile choice. It renders predictably on both desktop and mobile feeds, taking up a solid chunk of visual real estate without risking strange alignment issues.
• Portrait (1080 x 1350 px): The heavyweight champion for mobile engagement. Because it utilizes the maximum vertical height allowed by the LinkedIn feed, it forces users to slow down their scroll. Note: Avoid going taller than 4:5 (like Instagram Stories dimensions), or LinkedIn will crop the top and bottom.
• Landscape (1200 x 627 px): Best reserved for link previews or wide cinematic photography. Because it’s short vertically, it leaves a lot of blank space on mobile screens, making it less effective for pure engagement posts.

2. Special Content Formats: Carousels, Videos, and Articles

Different formats require tailored dimensions to prevent automatic compression and awkward scaling:

• Document / Carousel Posts (PDF Slides): Carousels consistently yield some of the highest engagement rates on LinkedIn. Design your slides at 1080 x 1080 px (Square) or 1080 x 1350 px (Portrait), and always export and upload them as a PDF to preserve formatting.
• Native Video Thumbnails: For landscape videos, stick to 1920 x 1080 px (16:9). If you are producing mobile-first video content, vertical formats like 1080 x 1920 px (9:16) work seamlessly. Always upload a custom thumbnail to ensure crisp quality.
• Article Header Images: If you publish long-form content using LinkedIn Articles, use a 1200 x 627 px header image to ensure it looks clean at the top of your piece.

3. Profile and Company Page Dimensions

Your personal brand relies heavily on your profile presentation. Make sure your static profile assets match these guidelines:

• Profile Picture: 400 x 400 px minimum (1:1 aspect ratio). Keep your face centered, as LinkedIn overlays a circular mask on the display.
• Personal Cover/Banner Image: 1584 x 396 px (4:1 aspect ratio). Keep critical text and logos away from the bottom-left corner, where your profile picture overlaps on desktop.
• Company Page Cover Image: 1128 x 191 px.

4. Technical Specifications & File Best Practices

Getting the dimensions right is only half the battle. To keep your images crisp and avoid platform compression errors, keep these technical rules in mind:

• File Size Limit: Keep your post images under 5 MB (though files under 2 MB load faster and perform better).
• File Formats: Use JPEG for photographs and complex color gradients (smaller file size); use PNG for graphics, charts, screenshots, or text-heavy images to keep text crystal clear.
• Color Space: Design your graphics using RGB color profiles (not CMYK), as CMYK can distort colors when rendered on digital screens.

Summary Checklist for Your Next Post

1. Designing a graphic or quote? Go with 1080 x 1080 px (Square) or 1080 x 1350 px (Portrait).
2. Export format: Save as a PNG for text-heavy graphics or JPEG for photos.
3. The Mobile Test: Always preview your post on your phone before hitting publish to ensure no vital text or imagery gets cut off by responsive formatting.
