LinkedIn carousel size: 1080×1350 pixels
Use 1080×1350 pixels (4:5 portrait) for LinkedIn carousel slides. It takes up the most of the mobile feed, where most people scroll. Square 1080×1080 (1:1) also works but shows smaller. Save all slides as one PDF, one slide per page, and upload it as a document post. The free maker below exports exactly 1080×1350.
Step by step
- Pick one size for every page: 1080×1350 (4:5) for the most feed space, or 1080×1080 (1:1) if you reuse square Instagram slides.
- Keep text away from the edges and use large type, since most people read on a phone.
- Export all slides as a single PDF, one slide per page, in the order you want people to swipe.
- On LinkedIn, start a post, choose “Add a document”, upload the PDF and give it a title.

FAQ
What is the best size for a LinkedIn carousel?
1080×1350 pixels, a 4:5 portrait ratio. It fills more of the mobile screen than square slides.
Can I use 1080×1080 square slides?
Yes. Square slides work fine, they just take up less height in the feed than 4:5 portrait slides.
What file format does a LinkedIn carousel use?
A PDF uploaded as a document post. Uploading several images instead shows them as a grid, not a swipeable carousel.
Do all pages need the same size?
Yes, use one size for every page so the carousel doesn't jump between slides.
