LinkedIn Post Image Size Guide for 2026

Mastering the Size of LinkedIn Post Images: The Definitive Guide

Visuals can make or break your professional content. Whether you are building your personal brand or managing a corporate company page, using the wrong image dimensions on LinkedIn often leads to awkward cropping, pixelated graphics, or skipped posts.

Because LinkedIn serves a professional audience across both desktop computers and mobile phones, understanding the correct sizing requirements ensures your content always looks sharp and deliberate.

The Best Image Sizes for LinkedIn Feed Posts

Choosing the correct dimension depends entirely on the format of your post. Here are the core specifications to keep your visuals crisp:

• Landscape (1.91:1 Aspect Ratio): 1200 x 627 pixels
  • Best for: Link previews, broad landscape photography, and website shares. This format fits the classic feed card layout perfectly without unexpected edge clipping.
• Square (1:1 Aspect Ratio): 1080 x 1080 pixels
  • Best for: Standard single-image posts, quote cards, and infographics. Square posts take up more vertical feed space than landscape, making them a reliable choice for both mobile and desktop viewers.
• Portrait (4:5 Aspect Ratio): 1080 x 1350 pixels
  • Best for: High-engagement visual storytelling. Because a significant portion of LinkedIn users browse via mobile devices, portrait images claim the most physical screen estate in the mobile feed, driving higher view times and interaction.

Quick Reference: Other Essential LinkedIn Image Dimensions

If you are updating your wider profile or setting up interactive documents, keep these auxiliary dimensions handy:

| Asset Type | Recommended Dimensions | Aspect Ratio |
| :— | :— | :— |
| Profile Photo | 400 x 400 pixels | 1:1 (Circular crop) |
| Personal Banner / Cover | 1584 x 396 pixels | 4:1 |
| Company Page Cover | 1128 x 191 pixels | ~5.9:1 |
| Carousel / Document Slides | 1080 x 1080 pixels | 1:1 (or 1080 x 1350 for portrait) |

Key Technical Best Practices

1. File Size and Formats: Stick to JPEG or PNG for static images. Ensure your files stay under the 5MB limit for standard post uploads to avoid error messages.
2. Avoid Upscaling: Always design your assets at or above the recommended pixel dimensions. If you upload an image that is too small, LinkedIn will stretch it, resulting in a blurry, unprofessional appearance.
3. Mind the Mobile Experience: Keep important text and focal points centered. Aggressive scaling on smaller screens means edge details can easily get lost or clipped.

By aligning your graphics with these dimensions, you ensure your professional updates capture attention for all the right reasons.
