Quick answer: A LinkedIn carousel is a document attached to a post, usually a PDF, that people swipe through page by page right in the feed. For a product launch it's the single best organic format on LinkedIn because it gives you 6–10 screens to make an argument instead of one image.

You can make one in an afternoon with no designer. Here's the complete workflow, including LinkedIn's actual file limits.

The specs

LinkedIn accepts PDF, DOCX, DOC, PPT, and PPTX files up to 100 MB and 300 pages (that's the document-ads limit LinkedIn publishes; organic posts use the same uploader). Ignore the big numbers. An organic launch carousel should be 6–10 pages. LinkedIn's own playbook recommends starting with 3–5 cards and testing more, which matches what actually works: short enough to finish, long enough to prove a point.

Design pages at 1080 px wide. Two ratios work:

  • 1080 × 1080 (square) is safe and reusable; the same pages work for Instagram.
  • 1080 × 1350 (4:5) fills more of the mobile feed, where most swipes happen.

Export as a PDF, one page per card.

The page order that works

The carousel has a job: cover, hook, proof, details, objection, CTA. Here's the exact 8-page structure I'd use for most product launches.

  1. Cover. The problem or the outcome, in a single line. Not the logo. Nobody swipes because a company logo looks nice.
  2. The hook. A specific claim or a number that makes the rest worth reading.
  3. The problem, in the reader's words. A screenshot of the painful workflow, or a line that describes what the reader does today.
  4. The product as the answer. One screenshot with one annotation showing what changed.
  5. How it works. Three steps, numbered. If it takes more than three, the product is doing too much for the story.
  6. Evidence or detail. A real metric, a comparison table, or a second screen. If you have no traction yet, use an honest capabilities page.
  7. The objection. Price, setup time, who it's not for. Addressing one out loud builds trust.
  8. Closing card. Product name, one-line summary, and the link in the caption.

The last page is often a wasted logo card. Make it a summary instead, because people screenshot and share the last page.

The caption

The post text does two jobs: state the post's premise and tell people to swipe. Keep the first 2–3 lines self-contained because LinkedIn truncates the rest. A formula that holds up:

  • Line 1: the claim or question.
  • Line 2: why it's worth swiping ("I walk through X in 8 cards").
  • Body: 2–3 lines of context.
  • End: the link. LinkedIn keeps links in organic document-post captions without demoting them the way X does.

Mistakes that show up every launch week

Building 14 cards. A carousel is not a pitch deck. Anything beyond 10 pages loses the casual swiper. Move the extra material to the landing page.

Screenshot salad. Six unannotated UI screenshots in a row is a manual, not a post. Every screenshot needs a one-line annotation that says what to look at.

Tiny text. Pages are viewed on a phone. If you have to zoom to read a card in the PDF viewer, it's unreadable in the feed. Headline 40+ px, body 24+ px is a reasonable floor.

No cover contrast. The cover is a thumbnail in a feed of people's faces and text posts. High contrast, one idea, readable at 120 px.

Reusing the Product Hunt gallery. The gallery is 1270 × 760 landscape at 1.67:1; the carousel is portrait or square. Same content, different composition. Recomposing matters, which is the same point as the social media image sizes table.

How the build actually goes

  1. Write the page outline as a list of one-liners before touching any design tool.
  2. Write the annotation for each page (what the reader learns on this card).
  3. Build the visual: cover, screenshots, steps, closing.
  4. Export PDF, open it on your phone, and swipe through in under 30 seconds.
  5. Post the PDF, caption, and link.

If you start with the product description rather than a blank page, a tool like Neatico generates the carousel pages and captions directly, then you export the PDF and post it. That keeps the whole thing to around 20 minutes.

Frequently asked questions

How many slides should a LinkedIn carousel be? 3–5 to start, 6–10 for a launch. The limit is 300 pages but nothing organic should approach it.

Do carousels work better than regular images on LinkedIn? They get more dwell time when the content is genuinely sequential, which is why how-to and breakdown posts do well. A weak carousel does not outperform a strong single image.

Can I include a clickable link inside the PDF? The PDF's links generally don't work in LinkedIn's document viewer. Put the link in the caption and repeat it on the last card as text.

Can I use the same carousel for Instagram? Square 1080 × 1080 pages can be exported as individual images for Instagram. 4:5 pages also fit Instagram's feed format. Story 9:16 does not, and needs its own composition.

When in the launch week should I post it? On or the day after launch, after the audience has seen the announcement. A carousel posted cold converts less than one posted after a short teaser.

Now go build the cover first. If the cover isn't worth tapping, the seven pages behind it don't matter.
