Mastering LinkedIn Image Sizes: The Complete Optimization Guide
First impressions matter—especially on a professional platform where recruiters, clients, and partners decide within seconds whether to engage with your profile or scroll past your posts.
Using blurry, stretched, or awkwardly cropped images instantly cheapens your personal brand. To help you stand out, this guide breaks down every exact dimension, format, and best practice for LinkedIn profile graphics, banners, and feed posts.
1. Personal Profile Images
Your profile assets establish your identity before anyone even reads your headline.
- Profile Picture:
- Dimensions: $400 times 400$ pixels (1:1 aspect ratio)
- Max File Size: 8 MB
- Formats: JPG or PNG
- Pro Tip: Keep your face centered. LinkedIn crops profile photos into a strict circle, so make sure your corners won’t clip important parts of your headshot.
- Personal Background Banner:
- Dimensions: $1584 times 396$ pixels (4:1 aspect ratio)
- Max File Size: 8 MB
- Formats: JPG or PNG
- Pro Tip: Watch the overlap! On both desktop and mobile devices, your circular profile photo overlaps the bottom-left corner of your banner. Keep key text, logos, and graphics centered or pushed toward the right side to prevent them from getting blocked.
2. LinkedIn Feed Post Sizes
Choosing the right canvas size for your feed content determines how much screen estate your post commands. Since the majority of users browse LinkedIn on mobile devices, optimizing your dimensions drastically boosts visibility.
| Format | Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Portrait | $1080 times 1350$ px | 4:5 | Maximum mobile engagement; infographics and top-performing creator posts. |
| Square | $1080 times 1080$ px | 1:1 | Safe, reliable format that renders consistently across desktop and mobile. |
| Landscape | $1200 times 627$ px | 1.91:1 | Link previews, website shares, and formal corporate announcements. |
3. Specialized Content: Carousels & Video
If you want to share deep-dive educational content or moving media, stick to these specifications to avoid automatic compression errors:
- Carousel / Document Posts (PDFs or Slide Decks):
- Dimensions: $1080 times 1080$ pixels (Square) or $1080 times 1350$ pixels (Portrait).
- Keep each slide clean, legible, and formatted as a high-resolution PNG or PDF.
- Video Posts:
- Dimensions: $1920 times 1080$ pixels (16:9 Landscape) or $1080 times 1080$ pixels (Square).
- Max File Size: Up to 5 GB. Keep clips concise to maintain high viewer completion rates.
Quick Rules of Thumb for Design Success
- Use PNG for Graphics & Text: If your graphic includes heavy typography or logos, export as a PNG to prevent fuzzy pixelation. Use JPG for standard photographic images.
- Preview Before Publishing: Always check how your profile banner and posts look on a mobile phone screen before moving on. Mobile formatting cuts off edges much more aggressively than desktop monitors.
