Key takeaways
- The LinkedIn carousel maker exports your slides as one PDF, 1080 px wide in the 4:5 portrait shape, and runs in your browser.
- LinkedIn recommends images 1,080 px wide with an aspect ratio between 3:1 and 4:5, so 1080 x 1350 is the tallest slide inside that range.
- Photo posts accept JPG, PNG, WebP, HEIC or GIF files up to 10 MB each, with up to 20 images per post.
- A carousel is uploaded to LinkedIn as a document post, which the feed shows as swipeable slides.
A LinkedIn carousel maker turns slides you type into a single PDF sized for LinkedIn: 1080 px wide, in the 4:5 portrait shape, with one idea on each slide. You then upload that PDF as a document post, and the whole process happens in your browser.
How do you make a LinkedIn carousel?
- Write the slides
Put one idea on each slide: an opening slide with the hook, then the steps or main ideas, then a closing slide. - Choose the shape
The 4:5 portrait format covers the largest share of a phone screen. - Style it and check it
Keep the text big enough to read on a phone and away from the edges of each slide. - Export
Download the single PDF and upload it to LinkedIn as a document post.
What size should LinkedIn carousel slides be?
LinkedIn turns a document post into slides that readers swipe through in the feed. For images, LinkedIn's own guidance is a width of 1,080 px and an aspect ratio anywhere from 3:1 to 4:5. A 1080 x 1350 portrait slide sits at the tall end of that range, so it fills the most space on a phone without being cropped.
What are the LinkedIn image sizes in 2026?
A photo post takes JPG, PNG, WebP, HEIC or GIF files. Each file can be up to 10 MB, and one post can hold up to 20 images. LinkedIn recommends 1,080 px of width and an aspect ratio between 3:1 and 4:5 for photo posts. Two other common formats:
| Where it appears | Pixels | Aspect ratio |
|---|---|---|
| Feed post, horizontal | 1200 x 627 | 1.91:1 |
| Profile cover (banner) | 1584 x 396 | 4:1 |
To check a file you already have, run it through the LinkedIn image size checker.
What does the tool do with your file?
Everything happens on your device. The tool reads the pixel dimensions in the browser, draws the content onto a canvas, crops it to the shape you chose and encodes it again at the exact export size. No upload request is sent, and metadata such as an EXIF location is left out of the exported file.
Why does the slide shape matter in the feed?
People browse LinkedIn mostly on their phones, and a taller image covers more of the screen. Among the shapes most feeds display without cropping, 4:5 portrait is the tallest, so it stays in view longer than a wide horizontal image.
The format earns the first glance. How many people see the post after that depends on the reactions it gets in its first hours.

What should you do after the carousel is posted?
A well-sized file gets the first look; reactions in the first hours decide who sees it next. On LinkedInLikes, members like each other's posts by hand from their own LinkedIn accounts. You sign up with email, get 100 starter points for your own posts and add more by liking other members' posts.
