LinkedIn is one of the most powerful platforms for B2B marketing, personal branding, and professional networking. However, many marketers miss out on engagement simply because their visuals are not optimized for the platform. Using the right sizes for profile pictures, banners, posts, videos, and ads ensures your content looks professional and performs better.

1. LinkedIn Profile Picture Size

Your profile picture creates the first impression for connections, recruiters, and clients. Optimizing it is crucial:

  • Recommended size: 400 x 400 pixels
  • Format: PNG or JPEG
  • Tips: Use a clear, professional headshot. Avoid cluttered backgrounds and ensure proper lighting.

2. LinkedIn Banner / Background Size

The banner image represents your brand or company identity. Correct dimensions help it display perfectly on all devices.

  • Personal profile banner: 1584 x 396 pixels
  • Company page banner: 1128 x 191 pixels
  • Tips: Keep logos and text away from edges. Use consistent brand colors.

3. LinkedIn Post Image Sizes

Visual posts attract more engagement than text-only posts. Optimizing image sizes ensures clarity and professionalism.

  • Multiple image carousel: 1080 x 1080 pixels (square images)
  • Tips: Use high-resolution images. Keep brand colors consistent and avoid overly complex designs.

  • Resolution: 1080p (1920 x 1080 pixels)
  • Aspect ratios: 1:2.4 – 2.4:1 (horizontal and vertical)
  • Duration: 3 seconds – 10 minutes
  • Format: MP4
  • Tips: Add subtitles, consistent branding, and an engaging thumbnail.

5. LinkedIn Company Logo Size

  • Tips: Use readable fonts, branded cover pages, and visually appealing graphics for better engagement.

8. Best Practices for LinkedIn Visual Content

  • Use branded templates consistently across all posts and ads.
  • Optimize for mobile users; LinkedIn’s majority audience is mobile.
  • Keep text and CTAs away from the edges of images and videos.
  • Test multiple formats—carousel posts, video snippets, PDFs—to see what performs best.
  • High-quality visuals with readable text improve engagement rates significantly.
