Recommended LinkedIn Carousel Dimensions
| Format | Aspect Ratio | Resolution (Pixels) | Performance |
|---|---|---|---|
| Portrait (Best) | 4:5 | 1080 x 1350 px | Highest Engagement |
| Square | 1:1 | 1080 x 1080 px | Standard |
| Landscape | 16:9 | 1920 x 1080 px | Low Mobile Retention |
Why 4:5 Portrait Ratio Dominates LinkedIn
Over 80% of LinkedIn interactions happen on mobile devices. A 4:5 aspect ratio (1080x1350px) occupies up to 30% more vertical screen space than a traditional square graphic, forcing the reader to pause their scroll and focus entirely on your carousel content.
