LinkedIn carousel size

The LinkedIn carousel size checker helps you confirm the slide dimensions before design or export. It compares the common LinkedIn carousel dimensions, calculates the aspect ratio from custom width and height values, and gives a practical fit result.

Use it for LinkedIn carousel size, LinkedIn carousel post size, LinkedIn carousel dimensions, LinkedIn carousel aspect ratio, LinkedIn carousel format, and LinkedIn document post size checks before uploading a PDF.

SlideDrift's published size guide and editor constants use 1080 x 1350 px as the default 4:5 portrait carousel size. The app also supports 1080 x 1080 px square slides for reusable layouts.

The size guide also lists 1920 x 1080 px landscape as useful for screenshots, webinar summaries, and presentation-style content, though portrait usually gives stronger mobile feed presence.

For a standard LinkedIn carousel, export as PDF, keep every page the same size, and open the final file before uploading. LinkedIn's document upload guidance supports PDF, PPT, PPTX, DOC, and DOCX, with a maximum file size of 100 MB and 300 pages.

PDF is usually the safest option because it preserves the visual layout better than editable document formats. If the PDF has complex layers, flatten or merge them before upload.

Basic planning is free and available without an account. The tool shows deterministic suggestions first so visitors can get a usable carousel direction immediately.

Anonymous visitors get 1 AI-assisted generation. Free accounts can use credits for more AI suggestions, and paid SlideDrift plans include monthly AI tool allowances before credits are charged.

AI suggestions help refine topics, angles, audiences, hooks, and briefs. SlideDrift remains the place where the final carousel is generated, edited, exported, and posted.

Enter 1080 x 1350 to confirm that the carousel matches SlideDrift's default portrait format before exporting a PDF.

Enter a Canva or Figma custom size to see whether the ratio is good for LinkedIn, may crop, too wide, or too tall.

Use the slide count guidance to decide whether the deck should be a 6-slide checklist, 8-slide framework, or deeper 9-12 slide tutorial.

Once the size is right, create the carousel in SlideDrift. The standard SlideDrift carousel format uses a 4:5 portrait canvas, then exports as a LinkedIn-ready PDF.

Templates can help avoid sizing mistakes because the frame, text scale, margins, and export workflow are already designed for LinkedIn carousel posts.
