LinkedIn Carousel Size Guide
LinkedIn carousels are just PDFs uploaded as a "Document" post, one page per slide. Getting the dimensions right is the difference between a carousel that fills the feed and one that looks cramped.
Portrait (4:5)
Takes up the most vertical space in the feed. The default choice for carousels.
Square (1:1)
Safe and simple. Slightly less feed real estate than portrait.
Landscape (16:9)
Works, but reads small on mobile. Better suited to slide decks than swipe carousels.
| File formats | PDF (recommended), PPT, PPTX, DOC, DOCX |
| Max file size | 100 MB |
| Max pages | 300 slides |
| Safe text margin | Keep text 60-80px from every edge |
How to build one
- 1. Set a custom canvas size. In Canva, Google Slides, or PowerPoint, set your page/slide size to 1080 × 1350 px (or the closest inches equivalent, 8 × 10 in at 135 DPI works too).
- 2. Design every slide at that size. Keep body text inside a safe margin, LinkedIn's UI overlays the corner with a page counter.
- 3. Export as a single PDF. One PDF, one page per slide, in order.
- 4. Upload as a Document post. LinkedIn turns each PDF page into one swipeable slide automatically.
