How to Create a LinkedIn Carousel Post (A Step-by-Step Guide for 2026)

By The Right Mix

Scroll through LinkedIn for sixty seconds and you’ll notice something. The posts people actually stop for are rarely a wall of text. They’re the ones with a swipe arrow tucked in the corner, a bold headline on slide one, and a “there’s more, keep going” energy: the carousel.

There’s good reason for that reaction. According to Buffer’s analysis of more than 52 million posts across 200,000-plus accounts, carousels are currently the best-performing organic format on LinkedIn, comfortably outpacing images, video and plain text. If you’ve been putting off making one because “design isn’t your thing,” here’s the good news: it’s far more about discipline than talent, and you don’t need a design degree to get it right.

A Quick Reality Check Before You Start

Here’s something worth knowing before you open a design tool. LinkedIn doesn’t have a dedicated “carousel” button any more. What you’re actually creating is called a document post. You design your slides, export them as a single PDF (or a PowerPoint or Word file), and LinkedIn automatically turns every page into a swipeable card in the feed. Most people still call the end result a “carousel,” and we will too, but understanding what’s happening behind the scenes explains a few of the rules below, especially around sizing, file format, and why uploading separate images won’t get you the result you want. If you’ve come across older guides recommending a square 1200 x 1200px image, that was accurate once. Specs have shifted as the feature itself has matured, so it’s worth working from current guidance rather than a screenshot someone saved a few years ago.

1. Start With Your Hook, Not Your Design Tool

Before you open Canva, PowerPoint or Figma, write the headline for your very first slide. This single line decides whether anyone swipes through to slide two, so it deserves more of your attention than any font choice or colour scheme. Frame it as a bold claim, a surprising number, or a question your audience already asks themselves. “Why isn’t anyone commenting on your posts?” will always outperform “5 Social Media Tips.” If you run an NGO, that might be “Why do donors give once and never come back?” If the hook doesn’t land, the rest of the deck never gets seen.

2. Set Your Canvas to the Right Size

Most design tools let you set a custom page size before you start designing. For LinkedIn document posts, the safest options in 2026 are 1080 x 1080px (square) or 1080 x 1350px (portrait). Portrait takes up more screen space on mobile, where the bulk of your audience is scrolling, so it tends to hold attention a little longer. Whichever you choose, keep every single slide in the deck exactly the same size. LinkedIn applies the dimensions of your first page to the whole document, so one inconsistent slide further into the deck can throw off the entire layout.

3. Outline One Idea Per Slide Before You Design Anything

This is the step people skip, and it always shows. Write your content out as a simple list first: one slide, one idea, in a logical order, before you touch a design tool. Aim for somewhere between six and ten slides in total. Fewer than that and you probably didn’t need a carousel in the first place. More than that and people tend to drop off before they reach your call to action. If you can remove a slide without losing the thread of the story, remove it.

4. Design for a Thumb, Not a Desktop

Assume almost everyone will read this on a phone screen. Use a font size of at least 30pt, limit each slide to one core message (roughly 40 to 50 words is a sensible ceiling), and check that your text has strong contrast against the background. A small arrow, or the word “swipe,” tucked into the corner of each slide is a simple, effective nudge that keeps people moving through the deck instead of bouncing after slide one.

5. Keep Branding Consistent From First Slide to Last

Use the same colour palette, font pairing and logo placement on every single slide. This does two jobs at once. It makes your content instantly recognisable in a crowded feed, and it signals professionalism in the few seconds someone takes to decide whether your post is worth their time. That consistency matters more to how credible you look than any single “pretty” slide.

6. End With a Clear Next Step

Your final slide is not the place to trail off. Tell people exactly what you want them to do: follow you, leave a comment with their own experience, download a resource, or book a call. Carousels are particularly good at generating saves and shares, but only if you give people a reason to act once they’ve reached the end. It’s also worth testing this format on your personal profile as well as your company page. One 2026 industry study put personal-profile carousels at over 60% higher engagement than the same format posted from a company page, so the same deck can perform quite differently depending on where it’s published from.

7. Export as a PDF and Upload It as a Document

This is where most first attempts go wrong. Uploading separate images won’t create a swipeable carousel. LinkedIn will simply stitch them into a static photo grid instead. Export your finished deck as a single PDF, never as a PNG or JPG, keep the file comfortably under 10MB, and preview it on your phone before you publish. Fonts can shift slightly on export, and you want to catch that before your audience does.

To actually post it: click “Start a post,” select the document icon (sometimes labelled “Add a document”), upload your PDF, add a short, descriptive title, write a caption of under roughly 150 words to set up the topic, and publish.

Common Mistakes Worth Avoiding

  • Text smaller than 24 to 30pt that’s unreadable on a phone screen.
  • Two or three ideas crammed onto a single slide instead of one.
  • Skipping the preview step, so a substituted font or misaligned element goes live without anyone noticing.
  • Publishing only from a company page without testing your personal profile, where this format often performs better.
  • A one-line caption that gives the algorithm, and your reader, nothing to work with.

The Bottom Line

A high-performing LinkedIn carousel has very little to do with design talent. It comes down to discipline: one strong hook, one idea per slide, consistent branding throughout, and a clear ask at the end. Get those four things right, and the platform tends to do the rest. It’s the same principle behind where Instagram’s algorithm is heading in 2026 (see our December Must Read): platforms increasingly reward content people want to save and revisit, not just scroll past, and a well-built carousel is one of the simplest ways to earn that.

If you’d like a hand turning your own expertise into a carousel that actually gets seen, whether that’s the strategy behind it, the copywriting, or the design itself, that’s exactly the kind of work we love at The Right Mix. Book a call [insert booking link] and let’s build your next one together.

Quick-Action Checklists

Audit Your Existing Content

  • Are your page titles and headings phrased as questions your audience actually asks?
  • Does each page directly answer one clear question or solve one specific problem?
  • Are your facts and claims backed up with links to credible sources?
  • Does every blog post have a named author with a short bio?
  • Is your Google Business Profile claimed, complete, and recently updated?

Writing a New Article or Page? Follow This Framework

  • Define the intent: Is this piece meant to answer a quick question (GEO) or drive deeper exploration (SEO)? It can do both.
  • Write a clear headline that includes the question or topic your audience is searching for
  • Open with the answer, do not make the reader scroll to find it
  • Add an FAQ section at the bottom with 3–5 direct questions and concise answers
  • Name your author and include a two-line bio with relevant credentials
  • Link out to credible sources, it builds trust with both readers and AI tools
  • Add schema markup if your platform supports it (most modern website builders do)
