LinkedIn Carousel Posts: Specs, Sizes, Examples

A LinkedIn carousel is a document post. You design your slides, export them as one multi-page PDF, upload it through the Add a document button in the LinkedIn composer, and LinkedIn turns each page into a swipeable frame in the feed. There is no carousel button, because LinkedIn removed the native carousel post in 2023. The PDF route is the format, not a workaround, and it is currently the highest-engagement post type on the platform. This guide covers the live specs from LinkedIn's own help pages, what the format looks like when it works, and how to produce a slide set that reads as one designed piece.

Can you still do carousels on LinkedIn?

Yes, in two ways, neither of them called a carousel in the interface.

• A document post. Upload a multi-page PDF, PPT, PPTX, DOC, or DOCX and each page becomes a slide viewers page through in the feed. This is what most people mean by a LinkedIn carousel.
• A multi-image post. Attach several separate photos to one post. LinkedIn calls it a multi-photo post, and viewers tap or swipe between the images.

The thing that no longer exists is the old native carousel. LinkedIn retired it along with profile videos and clickable in-image links in 2023, telling creators the features were not doing enough to help them share their experience (Social Media Today's report on the removal). Anything you read that describes clicking a carousel option in the composer predates that change.

The two surviving formats are not interchangeable. A document post keeps a fixed page order, renders type crisply because it is a vector or high-resolution PDF page, and can be downloaded by anyone who sees it. A multi-image post is easier to assemble but caps every image at 5 MB and forces the whole set into LinkedIn's photo aspect ratio range. Long-form teaching content goes in a document. A set of unrelated photos goes in a multi-image post.

LinkedIn carousel size, file limits, and format specs

These are the numbers LinkedIn publishes. Note that the document post limits are file limits, not design limits: LinkedIn does not publish a recommended pixel size or aspect ratio for organic document posts, only the constraints below.

The details behind those rows:

• 300 pages and 100 MB. LinkedIn's help page on uploading and sharing documents states that "the file size cannot exceed 100MB and 300 pages" and that the supported types are "PPT, PPTX, DOC, DOCX, and PDF." Nobody should ever hit 300. It is a ceiling, not a target.
• Every page has to be the same size. The same page adds that "PDFs with multiple sized pages must be fit to the same page size." A deck where one slide exports at a different dimension is the single most common broken carousel.
• You cannot swap the file later. LinkedIn's document uploads FAQ lets you revise the post title and description but not the document itself; fixing a typo on slide 4 means deleting the post and starting over, which throws away the engagement it has already earned. Proof the whole deck before you upload.
• Viewers can download it. The same FAQ describes viewing a document in full screen and clicking the download icon. Treat every slide as something that can leave LinkedIn as a file with your name on it.
• Multi-image specs are stricter than they look. LinkedIn's help page on sharing photos says "you can upload a maximum of 20 photos in a multi-photo post," that "the size limit for an upload is 5 MB," that a photo "must be at least 552 (w) x 276 (h) pixels, but we recommend 1080 (w) pixels," and that the aspect ratio "can range from 3:1 to 4:5 (width:height)." A tall 4:5 slide is the tallest shape allowed.

So what size should you actually design at? Since LinkedIn publishes no organic document spec, pick a shape and hold it across every page. Square at 1080 x 1080 and portrait at 1080 x 1350 are both safe and both common, and portrait claims more vertical space in the feed. For paid document placements LinkedIn is more prescriptive: its document ads specifications list vertical, horizontal, and square as accepted ratios, recommend keeping the document under 10 pages, and ask for standard PDF page layouts such as Letter, A4, or Tabloid, with layered PDFs flattened. Those recommendations are worth borrowing even for organic posts, especially the page count.

If you also need the profile-level image specs, the LinkedIn banner size guide covers the background photo and company Page cover dimensions.

How to create a carousel for LinkedIn

The upload flow comes straight from LinkedIn's document help page. It takes under a minute once the PDF exists.

1. Design your slides and export one PDF. Same page size on every page, in reading order. This is the whole job; the rest is uploading.
2. Click Start a post in the sharebox at the top of your LinkedIn homepage. On mobile, tap Post.
3. Click More, then the document icon. LinkedIn labels it Add a document. On mobile it is the More icon, then Document.
4. Click Choose file and pick your PDF from your computer, Dropbox, or Google Drive.
5. Add a title. This title shows under the document in the feed, so make it a reason to open rather than a filename. Click Done.
6. Write the post description. Hashtags and mentions are optional. The description is what earns the first swipe, so it carries as much weight as slide one.
7. Click Post.

Two things to check before you publish. Flatten the PDF if your design tool exported layers, and open the file at 100 percent to confirm no page came out at a different size, because LinkedIn requires uniform page dimensions and a mismatch is easier to see in the PDF than in the feed.

LinkedIn carousel examples and the structures that repeat

Look at LinkedIn carousel examples that get shared and the same handful of shapes keep showing up. They are structures, not templates, and they are what actually differentiates a good deck from a slow one.

• The numbered breakdown. A cover that promises a count, then one idea per page, then a closing page. Predictable in the good way: the reader knows exactly how much is left.
• The framework walkthrough. One model or process, one step per page, with a diagram page that shows the whole thing assembled. Works because the assembled page is worth saving on its own.
• The before and after. Two-page pairs comparing a weak version to a stronger one. The comparison does the teaching without much copy.
• The data cut. One chart or number per page pulled from something you measured, with the source stated. This is the format that gets quoted back at you.
• The teardown. A real artifact, an ad, a landing page, an email, annotated page by page. Concrete beats abstract, and it gives every page an obvious visual.

What they share: a cover page that states the payoff in one line, a fixed one-idea-per-page rhythm, and a final page that asks for something specific. What a good LinkedIn carousel looks like at a glance is a deck where you could cover the text and still tell it is one set.

On whether the format is worth the effort, Socialinsider's LinkedIn benchmarks, built from 1.3 million posts across 16,645 business pages between January 2024 and December 2025, put native documents at a 7.00 percent average engagement rate, ahead of multi-image at 6.45 percent, video at 6.00 percent, single image at 5.30 percent, and text at 4.50 percent, against a platform average of 5.20 percent. That is Pages data from one analytics vendor rather than a LinkedIn figure, and it measures business pages rather than personal profiles, so read it as a ranking of formats rather than a number to forecast against. As a ranking it is consistent: swipeable documents outperform everything else measured.

Designing a slide set that holds together

A carousel is a sequence, not a stack of images, and consistency across pages is what makes it read as one thing.

• Slide one sells the swipe, nothing else. One short line of large type. A dense cover page reads as work and gets scrolled past.
• Design for a phone-sized frame. The document viewer sits inside a feed post, so your page is rendered small. If the type would not survive being printed on a business card, it is too small.
• Lock one grid and keep it. Same margins, same type sizes, same position for page numbers and your handle on every page. This single decision does more for perceived quality than any amount of illustration.
• Keep the page count near ten. LinkedIn's own document ads guidance recommends under 10 pages. The 300-page ceiling is irrelevant to anyone making a carousel.
• Stay well inside the edges. The viewer chrome and page counter sit over the frame, so keep anything important away from the borders.
• Give the last page a job. Follow, comment, a named resource. A deck that just stops leaves the intent unspent.
• Watermark lightly. Because viewers can download the PDF, a small handle or URL on each page travels with the file.

What a LinkedIn carousel template fixes, and what it does not

A LinkedIn carousel template in Canva, Figma, or PowerPoint solves layout and page size: uniform dimensions, a working grid, text boxes in the right place. That is genuinely most of the mechanical risk removed. What it does not solve is looking like yours. Template decks are recognizable, and the popular ones are recognizable to exactly the audience you are posting to. The practical split is to keep a template for structure and replace the artwork, palette, and type with something specific to you, so the set has a system that is not shared with a thousand other posts.

Using a LinkedIn carousel generator for the artwork

The reason most carousels never get made is that page four through nine are the same design problem repeated, and doing it by hand is slow. A LinkedIn carousel generator changes the unit of work: instead of laying out each page, you describe the topic, the visual style, and the role each page plays, then generate the artwork as a matching set. The carousel graphics generator is built for exactly that, with slide roles for the hook, the middle content pages, and the closing call to action, plus a consistency instruction that carries identical margins, palette, and decorative motifs across the whole sequence. It outputs 4:5 or 1:1 slides, which both work as document pages once you export them at a single size.

One honest limitation. Image models still render small type unreliably, so the workflow that works is to generate the page art clean, with open space where the copy belongs, then set the actual text in Canva, Figma, or Keynote and export the PDF from there. You get a consistent visual system without trusting a model to spell. The same approach covers quote cards and, if the profile behind the posts needs work too, LinkedIn headshots. The AI social media post generator hub collects the rest of the formats.

If you are producing the same content for Instagram, the mechanics diverge completely: separate image files rather than one PDF, a 20-slide cap, and a different ratio range. The Instagram carousel guide covers that flow, and the Instagram post size reference has the pixel dimensions.

LinkedIn carousel ads are a separate product

Carousel ads still exist as a paid format in Campaign Manager, and they have nothing to do with document posts. They are a row of clickable cards, each with its own headline and destination URL. Per LinkedIn's carousel ads specifications: use "a minimum of two cards and a maximum of ten cards," images at a recommended 1080 x 1080 pixels in a 1:1 ratio, up to 4320 x 4320 pixels, a 10 MB maximum file size, JPG, PNG, or non-animated GIF, and up to 150 characters of introductory text to avoid truncation. Cards render at 312 x 312 pixels, which is small, so one idea per card and no fine print.

Paid document ads are the closer analogue to an organic carousel: same file types, same 100 MB and 300 page limits, up to five documents per ad. For the creative side of paid social generally, see AI generated ads.

The 5-3-2 rule and the 3-2-1 rule

Both come up constantly in LinkedIn advice and neither is a LinkedIn rule. The 5-3-2 rule is a content-mix ratio credited to TA McCann of Gist: for every ten posts, five share other people's relevant content, three are your own non-promotional content, and two are personal. The 3-2-1 rule is a looser variant of the same idea with different proportions, used inconsistently enough that it has no fixed definition. LinkedIn publishes neither. They are posting-cadence heuristics, so they say nothing about how to build a carousel, and treating them as platform requirements is a mistake.

The format is settled and the specs are short: one PDF, uniform page size, under 100 MB, aim for around ten pages, upload through Add a document. Everything that decides whether the carousel works happens before the upload, in a cover page worth swiping and a visual system consistent enough that the set reads as one piece.
