LinkedIn Carousel Size
LinkedIn carousels are document posts: you upload a PDF and each page becomes a swipeable slide. Design slides at 1080×1080 px (1:1 square) for the safest fit, or 1080×1350 px (4:5 portrait) for more height on mobile. Keep it to ~8–12 slides.
| Placement | Pixels | Ratio | |
|---|---|---|---|
| Square (recommended) — 1:1 Safest; fits desktop + mobile |
1080×1080 | 1:1 | |
| Portrait — 4:5 More height on mobile feed |
1080×1350 | 4:5 | |
| File format Export slides to one PDF, upload as document |

| Slides Max 300 pages; 8–12 performs best |

It's a PDF, not images
LinkedIn has no native carousel for photos — you create one by uploading a PDF document. Each PDF page becomes a slide. Design at 1080×1080 px (1:1) so slides look right on both desktop and mobile.
Square vs portrait
Square 1:1 (1080×1080) is the safe default. Portrait 4:5 (1080×1350) grabs more vertical space in the mobile feed but can be cut off on desktop. Keep critical text away from the bottom edge.
Keep it short
Technically a PDF can be up to 300 pages, but 8–12 slides hold attention best. Put the hook on slide 1 and a clear CTA on the last slide.
