Mastering LinkedIn’s visual real estate is one of the most practical ways to stand out in a crowded feed. Whether you are building your personal brand or managing a corporate page, blurry, awkwardly cropped, or pixelated images instantly undermine your credibility.
Because LinkedIn formats your content differently across desktop monitors and mobile screens, getting the dimensions right matters. This comprehensive guide covers the optimal LinkedIn post image sizes, profile dimensions, and layout rules to keep your content looking crisp.
1. LinkedIn Feed Post Image Sizes
When posting images directly to your feed, you have three primary orientation options. Choosing the right one depends entirely on the type of content you are sharing.
| Format | Recommended Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Square | 1200 x 1200 px (or 1080 x 1080 px) | 1:1 | Infographics, quote cards, general updates |
| Portrait / Vertical | 1080 x 1350 px | 4:5 | Mobile-first content, deep dives, high engagement |
| Landscape | 1200 x 627 px | 1.91:1 | Link previews, horizontal landscape photography |
- The Square Format (1:1): This is the ultimate “safe bet.” It renders reliably without unexpected crops on both mobile apps and desktop browsers.
- The Portrait Format (4:5): If engagement is your primary metric, portrait is your best friend. Because a large majority of professionals browse LinkedIn on their phones, a 1080×1350 px image takes up significantly more vertical screen space, forcing readers to slow down as they scroll.
- The Landscape Format (1.91:1): This is the traditional widescreen format. While it works well for landscape photography, it leaves a lot of empty, wasted space on mobile screens and is mostly recommended for link share thumbnails.
2. Profile and Company Page Dimensions
First impressions happen in fractions of a second. If your header image is blurry or cut off by your profile picture, visitors notice.
- Personal Profile Photo: 400 x 400 px (1:1 ratio, cropped into a circle; keep your face centered).
- Personal Background Banner: 1584 x 396 px (4:1 ratio). Keep in mind that your profile photo sits in the bottom-left corner on desktop, so avoid placing critical text or logos there.
- Company Page Logo: 400 x 400 px.
- Company Page Cover Banner: 1128 x 191 px (Note: Keep key text and branding centered to account for responsive scaling across different screens).
3. Carousels and Document Posts
Document posts (PDFs uploaded as swipeable carousels) remain one of the highest-performing formats on LinkedIn for educational and thought-leadership content.
- Recommended Slide Size: 1080 x 1080 px (Square) or 1080 x 1350 px (Portrait).
- File Format: Always upload as a clean PDF.
- Design Tip: Keep text sizes large (at least 24pt equivalent) and ensure your margins leave plenty of breathing room so LinkedIn’s native UI elements don’t overlap your text.
Quick Technical Checklist Before You Publish
- File Formats: Stick to PNG for graphics, charts, and images containing text (to prevent compression artifacts and blurry edges) and JPG for standard photographs.
- File Size Limits: Keep single feed images under 5 MB.
- Design for Mobile First: Over half of your audience is viewing your graphics on a smartphone screen. If you have to squint to read your graphic on a small screen, scale up your fonts and simplify your layout.
