LinkedIn Carousel Size: Dimensions, PDF Limits and Export Checklist

For a text-led LinkedIn carousel, start with 1080 × 1350 px (4:5 portrait), export one PDF and keep every page the same size. Square 1080 × 1080 px also works. Those are design presets, not mandatory platform dimensions.

The actual document-upload ceilings are 100 MB and 300 pages. This reference was checked on October 3, 2026 against LinkedIn's document help. It covers organic document posts, not paid carousel-ad specifications.

LinkedIn carousel dimensions

On a narrow screen, scroll sideways to read every column.

Pick the canvas around the content. A wide process diagram may need landscape; a short explanation may need portrait. None of these sizes guarantees distribution.

PDF pages are described by page dimensions rather than a required pixel resolution. Set the canvas in your design tool, then check the exported page ratio. Do not merely increase image resolution while leaving the document at the wrong shape.

Official upload limits vs our recommendations

On a narrow screen, scroll sideways to read every column.

“6–12 slides” and “under 10 MB” can be useful working targets, but they are not LinkedIn rules or evidence of better performance. A five-page checklist is better than ten slides padded to meet a supposed optimum.

A concrete slide plan

Suppose the topic is reviewing a project brief before starting work. A six-page outline could be:

1. Name the mistake the reader can avoid.
2. Show the ambiguous request.
3. Ask what outcome would count as success.
4. Show one constraint that changes the decision.
5. Give a short review checklist.
6. State the next action.

This is an illustrative structure, not a measured winning post. Use your real evidence; do not add invented client results.

The downloadable storyboard worksheet gives you blank rows for the slide job, copy, visual and evidence check. It is a planning worksheet, not a designed slide deck or carousel generator. See carousel examples for more structures.

Export checklist

• All pages use the same size and are in the intended order.
• Body text is readable at a narrow mobile viewing size.
• Important words are away from the edges.
• Fonts, links and graphics survive export.
• Text remains selectable where possible, rather than every page being a flattened screenshot.
• The PDF is within 100 MB and 300 pages.
• Sensitive client information and unsupported results have been removed.

Leave enough room for readable copy. If a slide needs tiny type to fit, reduce the words or split the idea. A larger canvas is not a cure for a compressed article.

Upload, caption and corrections

Upload the finished file as a document, not a set of separate images. Keep a local source copy. LinkedIn's help says the document itself cannot be changed after upload; an incorrect PDF may require replacing the post.

Check the accompanying caption against the 3,000-character post limit. Use the character counter and post preview for the text. The preview does not validate a PDF's typography or reproduce every LinkedIn device.
