How to Make a LinkedIn Carousel: Sizes, Examples, and How to Post

To make a LinkedIn carousel, create a multi-page document, export it as one PDF and upload it with the document option in a normal post. LinkedIn calls this a document post. Use a carousel when the reader needs a sequence or visual comparison; a single short point may be clearer as text.

The steps below cover canvas choices, export checks and publication. The design sizes are working presets, not platform-required dimensions or engagement guarantees.

TL;DR

• 📄 A LinkedIn carousel is a document post. Upload a multi-page file and each page becomes one swipeable slide.
• 🧩 There is no carousel button. Use the document upload option, then LinkedIn renders the PDF as a carousel in the feed.
• 📐 Choose a design preset. Portrait 1080 x 1350, square 1080 x 1080 and landscape 1920 x 1080 are options to test for readability.
• 🧾 LinkedIn recommends PDF. PPT, PPTX, DOC and DOCX are also accepted; inspect the exported and uploaded file.
• 🔁 Every slide needs the same dimensions. Mixed page sizes can break the display or make the deck look sloppy.
• 🪶 Keep it light. LinkedIn permits up to 300 pages and 100 MB. Shorter decks and smaller files are practical choices, not guarantees of engagement.
• 🪝 The caption still matters. Use the carousel for depth, then use the post text to frame the promise and earn the first swipe.

What is a LinkedIn carousel?

A LinkedIn carousel is a post where readers swipe sideways through several slides inside the feed. It feels like a native carousel, but the actual post type is a document post.

Here is what is happening behind the scenes. You create a file with multiple pages. Each page is one slide. You upload that file to LinkedIn as a document. LinkedIn turns the pages into a swipeable deck that people can move through without leaving the feed.

That is why the most practical answer is: a LinkedIn carousel is a PDF document post.

LinkedIn's document guidance, checked October 4, 2026, recommends PDF and also accepts PPT, PPTX, DOC and DOCX. Export one file with consistent page sizes, flatten multi-layer PDFs when needed, and check fonts and links before upload. The guidance does not promise identical rendering across devices.

LinkedIn carousel size and dimensions

Choose the LinkedIn carousel size before you design the first slide. Resizing a finished deck is painful, and mixed page sizes can break the display.

The simple rule: every slide in the PDF must use the same dimensions.

On a narrow screen, scroll sideways to read every column.

Start with portrait or square if it fits the material. A landscape deck can be appropriate for an existing diagram, but shrinking a dense presentation into a phone-sized viewer can make labels hard to read. Preview it at a realistic small size instead of inferring readability from the canvas ratio.

For preset comparisons and export checks, see our LinkedIn carousel size guide. None of these pixel dimensions is an official document requirement.

The official document limits are 300 pages and 100 MB, checked October 4, 2026. These are ceilings, not targets. Keep the file compact without making it unreadable, and remove repetitive slides. After publication you can edit the post description or remove the post, but not replace its document, so review the file before posting.

How to post a carousel on LinkedIn

Once the deck is ready, posting it is straightforward. The upload flow changes small labels from time to time, but the underlying process is the same.

1. Design your slides. Choose a consistent canvas that fits the material. Put one idea on each slide, with readable text and enough spacing. Check labels and any source notes at phone size.

2. Export the deck as one PDF. Do not upload one file per slide. Export the full deck as a single PDF, with every page the same size. Open the PDF before posting and quickly check that the order, spacing, and page sizes look right.

3. Start a new LinkedIn post. Go to your feed and click the normal post composer. You are not looking for a special carousel composer.

4. Add a document. Choose the document option, sometimes shown as a document icon or hidden behind a more menu. This is the option that turns your PDF pages into swipeable slides.

5. Upload the PDF. Select the PDF and give the document a short title. The title should describe the value of the deck, not your internal file name. A title like 7 client onboarding mistakes is clearer than carousel final v4.

6. Write a hook caption. The caption above the carousel still does important work. The first line should tell people why the deck is worth swiping. If you want to check how the caption will look before you publish, use the LinkedIn post preview.

7. Publish and stay nearby. After you post, reply to early comments while the conversation is fresh. A carousel can hold attention, but comments still help the post become a real discussion.

If the caption is the part slowing you down, draft a few options with the LinkedIn post generator, then rewrite the best one until it sounds like you. The upload is mechanical. The hook is where the post earns the swipe.

What makes a good LinkedIn carousel?

A good LinkedIn carousel feels easy to finish. The reader understands slide one immediately, knows why to keep swiping, and gets one clean idea per slide.

The basic shape is simple:

• Slide one earns the stop with a clear problem, promise, or tension.
• Each middle slide moves one step forward.
• The last slide gives a next step, such as save this, try this, comment with a question, or use the framework.

The mistake is treating every slide like a mini blog post. A carousel is not the place for dense paragraphs. It is closer to a guided sequence of thoughts. One slide, one point. If you need three paragraphs to explain a slide, the idea probably needs two slides.

Here are a few LinkedIn carousel examples by structure, without pretending they came from a famous brand.

The how-to teardown. Use this when your reader wants a process. Slide one names the outcome. The next slides walk through each step. The final slide summarizes the sequence and gives the reader one thing to try. Example concept: how to turn a client call into three LinkedIn posts.

The listicle. Use this when the value is a set of examples, mistakes, prompts, or checks. Slide one promises the number. Each middle slide gives one item and one short explanation. Example concept: 9 first lines that make a LinkedIn post easier to read.

The story. Use this when the lesson only makes sense with context. Slide one opens with the tension. The middle slides show what changed. The final slide lands the lesson. Example concept: the post I almost deleted, and what it taught me about writing for the right people.

The framework. Use this when you want people to remember a way of thinking. Slide one names the framework. Each middle slide explains one part. The last slide shows how the pieces fit together. Example concept: a 4-part checklist for turning expertise into a post idea.

If you are stuck on the angle, start with LinkedIn post ideas. Many text post ideas become better carousels when the reader needs a sequence, a checklist, a visual comparison, or a framework they might save. For ready-made structures, see our LinkedIn carousel examples, six slide-by-slide skeletons you can adapt.

Check whether the carousel was useful

Before publication, ask someone in the intended audience to read the exported deck on a phone. Can they identify its point, read each label and use the final step without your explanation? Remove a slide that only repeats another one.

After publication, record the goal and observation period, then compare similar topics and formats at the same age. Relevant replies, saves or follow-up work can matter for different goals. A swipeable format alone is not evidence of extra reach or a causal dwell-time advantage.

How to write the slides without sounding generic

The hardest part of a LinkedIn carousel is not exporting the PDF. It is writing the words that go on each slide.

A strong deck needs the same things as a strong text post: a clear hook, a specific reader, one point at a time, and a reason to keep going. Our guide on how to write a LinkedIn post applies almost directly. The first slide is your hook. The middle slides are your body. The final slide is your close.

Before you design, write the deck in plain text. One line for the first slide. One idea for each middle slide. One final line that tells the reader what to do next. If it does not work as a simple outline, design will not fix it.

The deck is only as strong as the words on each slide. WriteHero helps you turn a rough idea into hook options, slide copy, and a caption that still sounds like you. Use the LinkedIn post generator to draft the words, then use the LinkedIn post preview to check the caption before you publish.

Once the words are ready, lay them out on your chosen consistent canvas, inspect the exported PDF and upload it as a document. WriteHero's post generator can help with text; it is not an automatic carousel design generator.
