Carousel size guide. The carousel's first slide, posted on LinkedIn by SlideDrift.

The best LinkedIn carousel size is 1080 × 1350 px, a 4:5 portrait page. Use 1080 × 1080 px for a square carousel you also want to post elsewhere. Either way, upload it as one PDF with every page the same size.

  • Portrait, 1080 × 1350 px: the most room in the mobile feed. The best default.
  • Square, 1080 × 1080 px: compact, and easy to reuse on other platforms.
  • The file: a PDF of up to 100 MB and 300 pages, every page the same size, with no layers or animations.

LinkedIn doesn't publish an official carousel size. A carousel is a document post, and LinkedIn's help page sets the file rules rather than pixel dimensions. In practice, carousels use one of three page shapes:

FormatDimensionsBest for
Portrait (4:5)1080 × 1350 pxMost carousels: the most feed space on a phone
Square (1:1)1080 × 1080 pxShort copy, quotes and posts you'll reuse on other platforms
Landscape (16:9)1920 × 1080 pxExisting presentation slides; small in the mobile feed

Here's this size guide as a carousel, made in SlideDrift.

  2. 02The default, 1080 × 1350, 4:5 portrait. Go portrait first. A 4:5 page fills more of the phone screen and gives every slide room for a big headline and one point.
  3. 03The alternative. Square, 1080 × 1080 px. Use square for short copy, quotes or a carousel you'll also post on Instagram. It holds less, so edit tighter.
  4. 04The file. Upload one PDF. Up to 100 MB and 300 pages. LinkedIn recommends PDF for the best quality.
  5. 05Before export. Same size, no layers. Fit every page to one size and flatten layered PDFs. Animations show as still images, so don't rely on them.
  6. 06Final check. Read it on a phone first. Open the PDF once: page order, text size, one size throughout. You can't change the document after posting.

Portrait or square?

Start with portrait, 1080 × 1350 px. It gives each slide more height for a big headline and one supporting point, and it fills more of the screen in the mobile feed.

Choose square, 1080 × 1080 px when:

  • you'll post the same carousel on Instagram or another platform;
  • each slide carries one short line, a quote or a single number;
  • you prefer compact, poster-like layouts.

Square slides hold less, so they need tighter editing. If a slide needs more than two short lines and one visual, go portrait.

PDF or PNG?

For a LinkedIn carousel, export a PDF. LinkedIn accepts PDF, PPT, PPTX, DOC and DOCX files, and recommends converting files to PDF for the best quality.

The PDF export guide covers export settings in more detail.

LinkedIn's file rules

From LinkedIn's help page:

  • File types: PDF, PPT, PPTX, DOC or DOCX.
  • Limits: up to 100 MB and 300 pages.
  • Page size: PDFs with pages of different sizes must be fit to one page size.
  • Layers: PDFs with multiple layers must be flattened or merged.
  • Motion: videos and animations show as still images.
  • After posting: you can edit the description or remove the post, but not change the document.

How many slides?

LinkedIn allows 300 pages, but most good carousels need 6 to 12.

SlidesBest for
3–5One quick point, a quote, a reminder
6–8A checklist, a mini framework, a list of mistakes
9–12A tutorial, a case study, an article summary
13+A detailed guide or research summary

The better question is how many slides the reader needs before the point is clear. The slide count guide goes deeper.

Keep it readable on a phone

The right size doesn't help if the text is too small to read.

  • One idea per slide, with a big headline.
  • Short lines instead of paragraphs.
  • High contrast between text and background.
  • Important text away from the edges.
  • No key information in tiny captions.

A quick test: look at each slide at phone size. If you can't read it at a glance, it's too dense.

FAQ

What size should a LinkedIn carousel be?

1080 × 1350 px, a 4:5 portrait page, is the best default. Use 1080 × 1080 px for a square carousel you also want to post on other platforms.

What file format should a LinkedIn carousel be?

A PDF. LinkedIn also accepts PPT, PPTX, DOC and DOCX files, but recommends PDF for the best quality.

How many pages can a LinkedIn carousel have?

Up to 300 pages and 100 MB. Most carousels work best with 6 to 12.

Should a LinkedIn carousel be square or portrait?

Portrait for most carousels, because it gives each slide more room and fills more of the mobile feed. Square suits short, visual or cross-platform carousels.
