LinkedIn Carousel Size and Format Guide 2026
LinkedIn carousels need to be easy to read on mobile.
That is the most important rule.
You can have a beautiful design, but if the text is too small or the pages are inconsistent, people will stop swiping.
This guide explains practical LinkedIn carousel sizes, formats, and design rules for 2026.
How LinkedIn Carousels Usually Work
The common LinkedIn carousel-style workflow is to upload a multi-page document.
Each page becomes part of the swipeable experience in the feed.
LinkedIn supports document uploads, and official LinkedIn help notes that documents can be shared from the post composer. LinkedIn also recommends that PDFs with multiple sized pages should be fit to the same page size.
That page consistency is important.
If one page is square, another is portrait, and another is landscape, the preview can feel broken.
Recommended Carousel Sizes
There is not one perfect size for every carousel.
However, these formats are practical:
1. Square format
A square carousel is simple and safe.
Common size:
1080 x 1080 px
Best for:
- Simple frameworks
- Quote slides
- Checklists
- Short educational posts
- Repurposed Instagram content
Square slides are easy to design and work across many platforms.
2. Portrait format
A portrait carousel gives more vertical space.
Common size:
1080 x 1350 px
Best for:
- Educational carousels
- Step-by-step guides
- B2B breakdowns
- Visual storytelling
- Posts with more text hierarchy
Portrait formats often feel stronger on mobile because they use more screen space.
3. Landscape format
Landscape can work, but it is usually less ideal for swipeable feed content.
It may be useful for:
- Presentation-style content
- Wide diagrams
- Data visuals
- Screenshots
But for most LinkedIn carousels, square or portrait is easier to read.
Best Format to Upload
For LinkedIn document-style carousels, PDF is the most common workflow.
You create each slide as a page, export the full carousel as a PDF, then upload it as a document post.
For advertising use cases, LinkedIn’s Document Ads specifications mention PDF, DOC, DOCX, PPT, and PPTX support with limits such as 100 MB and 300 pages. Organic posting interfaces may vary, so always preview before publishing.
How Many Slides Should You Use?
Most LinkedIn carousels work well with 6 to 12 slides.
A simple post might only need 5 slides.
A deeper guide might need 10 or 12.
Avoid making the carousel longer just to make it feel bigger.
Every slide should earn its place.
A practical structure:
- Hook
- Problem
- Insight
- Point 1
- Point 2
- Point 3
- Example
- Checklist
- CTA
Keep Text Large
Most people will see your carousel on a phone.
That means small text is a problem.
Use large headings.
Keep body text short.
Avoid putting full paragraphs on slides.
If your slide needs more than three or four short lines of body text, consider splitting it into two slides.
Use Safe Margins
Do not place important text too close to the edge.
Leave breathing room around the slide.
Safe margins help your carousel feel more polished and reduce the risk of text feeling cramped in previews.
A simple rule:
Keep key text and visuals inside the central area of the slide.
Use Consistent Pages
Every page should use the same canvas size.
This matters for PDF exports.
If your PDF has mixed page sizes, LinkedIn may show inconsistent previews or create a poor reading experience.
Before exporting, check:
- Same page size
- Same margins
- Same orientation
- Same brand styling
- Same export quality
Export Checklist
Before posting your LinkedIn carousel, check this list:
- The first slide has a strong hook
- Every slide uses the same size
- Text is readable on mobile
- The PDF pages are in the correct order
- The file opens correctly before upload
- There are no blurry screenshots
- The final slide includes a CTA
- The caption gives context
How InfoBlog Helps
InfoBlog helps you turn source content into carousel-ready visuals faster.
You can start with a blog post, PDF, URL, or document, then generate a structured carousel without designing every slide manually.
That is useful when you want to repurpose long-form content into a format that works better on LinkedIn.
