LinkedIn Personal Profile Image Sizes
Your LinkedIn profile is often the first impression professionals have of you. These image specifications ensure your profile looks polished across all devices.
Profile Photo
Your profile photo appears throughout LinkedIn—in search results, comments, messages, and connection requests. LinkedIn crops this image to a circle, so keep your subject centered.
| Specification | Requirement |
|---|---|
| Recommended Size | 400 × 400 pixels |
| Maximum Size | 7680 × 4320 pixels |
| Aspect Ratio | 1:1 (square) |
| File Format | JPG or PNG |
| Max File Size | 8 MB |
Pro Tip: Use a high-quality headshot with good lighting. Your face should fill approximately 60% of the frame. Avoid logos or group photos for personal profiles.
Profile Banner (Background Image)
The banner image is prime real estate for personal branding. Use it to showcase your expertise, promote a project, or reinforce your professional identity. Note that it displays differently on desktop and mobile—keep key elements centered.
| Specification | Requirement |
|---|---|
| Recommended Size | 1584 × 396 pixels |
| Aspect Ratio | 4:1 |
| File Format | JPG or PNG |
| Max File Size | 8 MB |
Pro Tip: Your profile photo overlaps the bottom-left corner of the banner on desktop. Design with a 20-40 pixel margin around important elements, and always preview on both desktop and mobile before publishing.

LinkedIn Feed Post Image Sizes
Organic posts in the LinkedIn feed support multiple image formats. Choosing the right dimensions ensures your content looks professional and captures attention as users scroll.

| Square | 1200 × 1200 pixels | 1:1 | Versatile for desktop & mobile |
| Portrait | 1080 × 1350 pixels | 4:5 | Mobile-first, maximum visibility |
File Specifications: JPG or PNG format, maximum 5 MB per image. LinkedIn supports images up to 36 megapixels, but optimize file size under 5 MB for faster loading.
Link Preview Images
When you share a link, LinkedIn automatically pulls the Open Graph image from the page. For best results, ensure your website's OG images are properly sized.
| Specification | Requirement |
|---|---|
| Recommended Size | 1200 × 627 pixels |
| Minimum Size | 640 × 360 pixels |
