# What is a LinkedIn carousel?

Canonical page: https://depost.ai/glossary/linkedin-carousel

**LinkedIn carousel:** A LinkedIn carousel is a multi-page PDF uploaded as a document post, which the feed displays as a set of slides readers swipe through one at a time.

Also called: LinkedIn document post, LinkedIn PDF post, swipe post.

Mechanically there is no carousel format on LinkedIn. You upload a PDF and the feed renders each page as a slide. That is why any tool that exports a PDF can produce one, and why the design constraint is page size rather than anything platform-specific.

They perform well because every swipe is a small decision the reader keeps making, and sustained attention is a strong signal. They also get saved more than text posts, which keeps bringing readers back long after the post stops circulating.

The format suits material with a natural sequence: a process, a checklist, a teardown, a before-and-after. One idea per slide, a first slide that works like a hook, and a last slide that tells the reader what to do next. Material without a sequence usually reads better as a text post than as slides invented to justify the format.

The most common failure is not design, it is text size. LinkedIn compresses uploads, so type that looked crisp in the design tool renders soft in the feed, and most amateur-looking carousels are a compression problem rather than a taste problem.

The caption still does real work. Readers meet the caption and the first slide together, and the caption is what earns the first swipe, so a carousel dropped into the feed with a one-line caption is leaving its own distribution on the table. Write it like a short post that happens to have slides attached.

Square pages are worth insisting on. They occupy more vertical space in the feed than landscape ones, which means more of a scrolling reader’s screen belongs to you.

**6.6%** average engagement on carousel posts, the platform’s highest-performing format (source: Benchmarks, 2026).

## In Depost AI

The Graphic Generator designs the carousel in your brand’s colors and type, learned from what you have published, and it arrives with the post rather than as a separate job afterwards. There is no second tool and no handoff, which is usually the reason carousels stop getting made.

## Questions people ask

### How many slides should a LinkedIn carousel have?

Eight to ten. Fewer feels thin, and completion rates fall off past ten. Each slide should carry a single idea.

### What size should LinkedIn carousel slides be?

Square works best, because it occupies more vertical space in the feed than a landscape slide. Export at a generous resolution and set type larger than feels necessary, since LinkedIn compresses what you upload.

- [Dwell time](https://depost.ai/glossary/dwell-time): Dwell time is how long a reader spends on a post before scrolling on, used as a ranking signal because it measures actual attention rather than the deliberate act of clicking a button. LinkedIn measures it from the moment at least half the post is on screen, and reports none of it to the person who wrote the post.
- [First comment](https://depost.ai/glossary/first-comment): The first comment is a comment the author adds to their own post at publication, conventionally used to carry links, sources, or a follow-up question without putting them in the post itself.
