Question 1

What is the best size for a LinkedIn carousel?

Accepted Answer

The most recommended size is 1080 x 1350 pixels, a 4:5 portrait ratio, because it takes up the most vertical space in the mobile feed. 1080 x 1080 pixels, a 1:1 square, is a reliable alternative that looks good on both desktop and mobile.

Question 2

What aspect ratio should a LinkedIn carousel be?

Accepted Answer

Use a 4:5 portrait ratio for maximum mobile impact, or a 1:1 square ratio for a clean, balanced look. Avoid wide 16:9 landscape slides, which appear small on phones.

Question 3

How do I upload a carousel to LinkedIn?

Accepted Answer

LinkedIn carousels are document posts. Export your slides as a PDF (PowerPoint and Word files also work), then choose 'Add a document' when you create a post. Documents support up to 300 pages and 100 MB.

Question 4

How many slides should a LinkedIn carousel have?

Accepted Answer

LinkedIn allows up to 300 pages in a single document post. Most high-performing carousels stay between about 5 and 12 slides so readers actually finish them, but there is no strict minimum.

Question 5

Is the LinkedIn Carousel Size Checker free to use?

Accepted Answer

Yes, it is completely free and runs entirely in your browser. Enter any width and height to instantly see whether it matches a recommended LinkedIn carousel size.
