How to Create a LinkedIn Carousel: From Idea → Export
You've seen the swipeable slides that get more saves than a regular post. You open Canva, pick a template, and 40 minutes later you're stuck on slide 3 wondering if the dimensions are right.
There's no mystery here - LinkedIn carousels are PDFs. What trips people up is sequencing: writing slides before the structure is set, designing before the copy is finalised, picking a tool before knowing what kind of carousel they're making.
The seven-step process below runs in the order that produces the fewest revisions. Idea first, design last.
Key Takeaways
- A LinkedIn carousel is a PDF (or PPT/DOC) uploaded via "Add a document" - there's no separate carousel feature like Instagram.
- Hard limits: 100 MB file size, 300 pages. Engagement sweet spot: 8–12 slides at 1080×1350 px (4:5 portrait).
- Lock idea, outline, and copy before opening a design tool. Designing first is the biggest reason carousels stall mid-build.
- Always export PDF. PPTX/DOCX lose fonts and alignment across devices.
- Slide 1 is the entire hook. If it doesn't earn the first swipe in two seconds, the rest is wasted.
Short Answer
How do you create a LinkedIn carousel? Write the idea and outline first, then draft slide copy in a doc, then design in a tool like Canva or Figma at 1080×1350 px, then export as PDF (under 10 MB), then upload through LinkedIn's "Add a document" button. Aim for 8–12 slides with one idea per slide. Skipping the copy step before designing is the most common reason carousels never get finished.
LinkedIn doesn't have a dedicated carousel post type - what people call a "carousel" is technically a document post. You upload a PDF (or PPT/DOC) under 100 MB and up to 300 pages, and LinkedIn renders it as a swipeable deck in the feed. Source: LinkedIn Help - Upload and share documents on LinkedIn
What a LinkedIn carousel actually is
A LinkedIn carousel is a document post. You compose a post, click "More" → "Add a document," and upload PDF, PPT, PPTX, DOC, or DOCX up to 100 MB and 300 pages. Each page becomes a slide.
There's no separate carousel uploader. Two consequences follow:
- You can't stitch a series of images into a carousel. Instagram works that way; LinkedIn doesn't. Combine slides into one document file before uploading.
- You can't edit a document post after publishing. Typo on slide 4? Delete and re-upload. Every step before export matters more than people think.
A LinkedIn carousel is not a feature. It's a side effect of how LinkedIn renders multi-page documents. Treat it like designing a printable PDF that happens to live in a feed.
Specs that matter
Lock the canvas before you design anything. Mismatched dimensions are the single most common reason carousels look amateurish.
| Spec | Value | Notes |
|---|---|---|
| File format | PDF (recommended), PPTX, DOC, DOCX | Only PDF renders fonts consistently across devices |
| Max file size | 100 MB | Aim under 10 MB; under 3 MB is ideal |
| Max pages | 300 | Engagement sweet spot is 8–12 slides |
| Recommended dimensions | 1080×1350 px (4:5 portrait) | ~33% more vertical screen space than square |
| Alternative | 1080×1080 px (1:1 square) | Use only if repurposing for Instagram |
| Avoid | A4, US Letter, 16:9 horizontal | Render at lower effective resolution on mobile |
| Color mode | RGB | CMYK looks dull on screens |
| Min body font | 32 pt at 1080 px wide | Anything smaller is unreadable on mobile |
| Safe zone | 80–100 px from edges | LinkedIn's UI overlays parts of the slide |
Pick 4:5 portrait for one reason: vertical screen space. On mobile, a 1080×1350 carousel occupies roughly a third more pixels than a square, which directly correlates with dwell time.
LinkedIn applies the dimensions of the first page to your whole deck. If page 1 is 1080×1350 and page 2 is 1080×1080, page 2 gets cropped or padded with white bars. Set the canvas size once at the start of the project - don't change it mid-design.
The 7-step process: Idea → Outline → Slide structure → Design → Copy → Export → Upload
The order matters. Most failed carousels were built in the wrong sequence.
Idea. Pick one specific problem one specific reader has. "How to write LinkedIn hooks" is too broad. "5 hook formulas for B2B founders in their first month on LinkedIn" is a carousel. Stuck? See LinkedIn carousel ideas for 30+ angles.
Outline. Write the slide-by-slide outline in a plain doc - not a design tool. One line per slide, one idea per slide. A 10-slide outline takes 15 minutes in a doc and two hours in Canva.
Slide structure. Map the outline onto a template: hook → context → content slides (one idea each) → summary → CTA. The structure stays the same whether you're teaching or storytelling.
Design. Open the design tool. Set canvas to 1080×1350. Build a template with brand colours, one display font, and one body font. Don't write final copy - paste outline as placeholder. The job here is layout, not writing.
Copy. With layout locked, refine the sentences. Pressure-test every line: does it earn the next swipe? A 12-slide carousel with one idea per slide outperforms a 6-slide deck with three ideas crammed onto each.
Export. Canva: Share → Download → PDF Standard. Figma: Export → PDF. Google Slides/PowerPoint: File → Download as PDF. Flatten if available - it locks fonts. Verify under 10 MB; compress with Smallpdf if not.
Upload. LinkedIn: "Start a post" → "More" → "Add a document." Choose the file, add a title (under 60 characters), write the post body. Preview on mobile before publishing - once posted, you can't edit.
The single biggest change you can make to your carousel process is to write all the copy in a plain text doc before opening a design tool. People who design first end up with carousels that look pretty but read poorly. People who write first end up with carousels that read well - and design always catches up.
Tools comparison
There's no single best tool - only the right tool for your context.
| Tool | Cost | Ease | Templates | Export quality | Collaboration |
|---|---|---|---|---|---|
| Canva | Free / $15 mo Pro | Easiest | 1000+ carousel templates | PDF Standard 96 DPI; PDF Print 300 DPI | Real-time + brand kit on Pro |
| Figma | Free / $15 mo per editor | Moderate learning curve | Community templates | PDF export preserves vectors | Best-in-class real-time |
| Google Slides | Free | Easy, familiar | Limited carousel templates | Decent; fonts can shift | Excellent (Docs-like) |
| PowerPoint | $7+ mo (M365) | Easy, slide-native | Few carousel templates | High-quality, reliable | OneDrive-based, lags Google |
| Keynote | Free (Mac only) | Easy on Mac | Sparse for LinkedIn | Excellent PDF rendering | iCloud-only friction |
| Dedicated (AdobeExpress, Postiv, CarouselMaker) | Free / $10–20 mo | Easiest if templates fit | LinkedIn-specific, pre-sized | Pre-optimised | Weaker than Figma/Google |
Trade-offs:
- Canva is fastest for a first carousel, but you'll outgrow its brand controls if you make carousels weekly. Its templates are also why many Canva carousels look the same.
- Figma wins when you want pixel control. Avoid it if you've never used a vector tool.
- Google Slides is underrated: free, collaborative, clean PDF export.
- PowerPoint and Keynote are fine for one-offs but lack carousel-specific templates.
- Dedicated tools save time only if your design needs match their templates.
Picking one today? Start with Canva. Move to Figma when consistency matters more than speed.
Slide structure templates
Use these as starting points. Each is a copy/paste outline to adapt before opening a design tool.
Template 1: The how-to carousel (8 slides)
Slide 1 - Hook: "5 ways to [outcome] for [reader] (without [pain])"
Slide 2 - Context: Why this matters / what most people get wrong
Slide 3–7 - Methods 1–5: Name + one-sentence explanation + example
Slide 8 - Summary + CTA: "Save this. Comment which one you'll try first."
Template 2: The framework carousel (10 slides)
Slide 1 - Hook: "The [Name] framework for [outcome]"
Slide 2 - Problem this framework solves
Slide 3 - Overview: 3–4 named steps
Slide 4–8 - Each step: what to do + one example + common mistake
Slide 9 - Worked example: all steps applied to one real case
Slide 10 - CTA: "Follow [@handle] for more frameworks"
Template 3: The case study carousel (12 slides)
Slide 1 - Hook: "How we [result] in [time] for [client type]"
Slide 2 - Starting point: numbers, situation, constraint
Slide 3 - What wasn't working and why
Slide 4–5 - The decision and the pivot
Slide 6 - The system we built (high-level)
Slide 7–9 - Each step of the system in detail
Slide 10 - Result: before/after numbers
Slide 11 - What we'd do differently next time
Slide 12 - CTA: link, comment prompt, or follow ask
Three rules apply to all templates:
- Slide 1 is the entire hook. Name a specific reader, promise a specific outcome - same as the first 2–3 lines of a regular LinkedIn post.
- Each content slide is one idea. Two ideas means the reader finishes neither before swiping.
- The last slide is always a CTA. Save, comment, follow, or click - never "thanks for reading."

Common mistakes and how to fix them
Designing before writing. Burns 90 minutes on slide 1 before you realise the deck has no point. Fix: outline in a doc first.
Wrong canvas size. A4 or US Letter PDFs render at lower resolution on mobile. Fix: set canvas to 1080×1350 px first.
Tiny fonts. Below 32 pt on a 1080 px canvas is unreadable on a phone. Fix: preview on your own phone - if you squint, it's too small.
Mixing aspect ratios. Two square slides in a portrait deck cause cropping. Fix: lock dimensions on slide 1 and don't change them.
Overcrowded slides. Three bullets, an icon, and a footer fighting for attention. Fix: one idea per slide. Two paragraphs means two slides.
No CTA. Ending with "hope this helps" wastes the attention you earned. Fix: end with a specific next step.
Uploading PPTX instead of PDF. Fonts substitute and alignment shifts. Fix: always export to PDF, even though LinkedIn accepts PPTX.
Not previewing on mobile. Desktop preview hides text overlapping the mobile engagement bar. Fix: open the draft on your phone before publishing.
Document posts cannot be edited after publishing. If you spot a typo or layout issue post-upload, the only fix is to delete the post and re-upload - which kills any momentum the original post had. Always preview on a real phone before hitting publish.

FAQ
What's the file size limit for a LinkedIn carousel? 100 MB and 300 pages is the hard limit. Aim under 10 MB for fast mobile loading; under 3 MB is ideal.
Can I make a video carousel on LinkedIn? No. Document posts are static-only (PDF, PPT, PPTX, DOC, DOCX). Video is a separate post type.
How do I preview my carousel on mobile before publishing? Save the post as a draft, switch to the LinkedIn mobile app, and review there. This catches text overlapping the mobile engagement bar - an issue that doesn't show up on desktop.
Square or portrait? 1080×1350 px (4:5 portrait) for LinkedIn-only. It takes about a third more mobile screen space and improves dwell time. Use 1080×1080 (square) only when repurposing for Instagram.
How do I repurpose a carousel? Each slide can become a standalone text post or thread tweet. The hook slide becomes a post hook; content slides become a numbered list post; the CTA stays the CTA. See how to repurpose content for LinkedIn.
8 slides or 15? The sweet spot is 8–12. Fewer than 5 looks thin; more than 15 loses attention before the CTA. Anywhere between 7 and 13 is safe.
