What size should a LinkedIn carousel be?

1080 x 1080 pixels for square pages or 1080 x 1350 for portrait, exported as a PDF and posted as a document. Portrait fills more of the mobile feed; square is the safest all-round choice.

What file type is a LinkedIn carousel?

A PDF uploaded as a document post. LinkedIn turns each page of the PDF into one swipeable slide — you cannot build a carousel from separate image files.

How many slides can a carousel have?

LinkedIn allows up to 300 pages, but most effective carousels stay between 6 and 12. Short enough to finish, long enough to teach something.

What is the maximum file size for a carousel?

100 MB. In practice, keep it far smaller by exporting at the exact page dimensions rather than at print resolution, so it uploads quickly and displays reliably.

Should I use square or portrait pages?

Portrait (1080 x 1350) takes up more vertical space in the feed, which tends to help visibility on mobile. Square (1080 x 1080) is more forgiving if your content mixes wide charts and text.

Why does text on my carousel look cut off?

The document viewer has rounded edges and overlay controls. Keep text and key details inside a margin of about 60 pixels on every side of the page.

LinkedIn Carousel Size Guide

A LinkedIn carousel is a PDF uploaded as a document post, so the page size of that PDF decides how every slide displays. This guide gives you the recommended dimensions for square and portrait carousels, the page count and file size limits, and the safe margins that keep text clear of the on-screen controls — everything you need to set up your document correctly the first time.

How it works

1Choose square (1080 x 1080) or portrait (1080 x 1350) pages.
2Set your design document to that exact page size before you start.
3Keep text inside the safe margins, about 60 pixels from every edge.
4Export as a PDF, then upload it to LinkedIn as a document post.

Set the page size before you design

The most common carousel mistake is designing at an arbitrary size — often a US Letter or A4 page — and discovering the proportions only after export. A letter page is taller and narrower than anything LinkedIn displays well, so slides end up with dead space or cramped type. Decide on square or portrait first, set your document to exactly 1080 x 1080 or 1080 x 1350 pixels, and design inside that frame from the start.

Most design tools let you set a custom canvas in pixels. If yours works in inches or points, set the unit to pixels for this project, or multiply: at 96 DPI, 1080 pixels is 11.25 inches.

Design for a phone screen

Most people read carousels on mobile, where a 1080-pixel page shrinks to a few hundred. Treat every slide like a billboard: one idea per page, headline-sized type, and heavy contrast between text and background. If you need more than a sentence or two to make a point, split it across two slides rather than shrinking the font.

Respect the safe margins. The viewer rounds the corners of your pages and floats navigation controls on top, so anything within about 60 pixels of an edge risks being clipped or covered. Page numbers, logos and calls to action all belong inside that inner zone.

Exporting the PDF

Export at the exact page size — do not scale up or add bleed and crop marks, which change the dimensions LinkedIn sees. Keep the file well under the 100 MB limit; a text-and-flat-colour carousel should come out at a few megabytes at most. If your export is far larger, your images are oversized: downsample them to the page dimensions.

Before you post, open the PDF and swipe through it once. Order errors and missing pages are easy to miss in a design tool and very public on LinkedIn.

Carousel or multi-image post?

If your content is a sequence that must be read in order — a framework, a story, a step-by-step — use a carousel. If it is a set of related photos that stand alone, a multi-image post of up to nine images is simpler and keeps the photos viewable at full size. The feed post image page covers the dimensions for that format.
