Creating a brilliant carousel only to find out the text is cut off or the images are pixelated when you upload it is incredibly frustrating.
LinkedIn document posts (carousels) have specific technical requirements. If you want your content to look professional and perform well in the algorithm, you need to follow the exact LinkedIn carousel size and specifications.
The Optimal Dimensions
When designing your slides, you have two primary choices for dimensions.
1. Portrait (Recommended)
2. Square (Standard)
Technical Specifications
Beyond just the width and height, you must adhere to LinkedIn's file constraints to ensure a successful upload.
Designing for the "Safe Zones"
LinkedIn's native document viewer overlays several UI elements on top of your PDF. If you place important text or logos in these areas, they will be hidden.
The Easiest Way to Handle Specs If you don't want to memorize aspect ratios, safe zones, and PDF export settings, use a dedicated LinkedIn Carousel Maker. The software automatically sets the correct canvas size, enforces safe zones, and exports a LinkedIn-optimized PDF with one click.
A Note on Image Quality
While you want to keep the file size reasonable, you must maintain image quality. When exporting your PDF from Canva, Figma, or Photoshop, ensure you are not compressing images so heavily that text becomes blurry. A crisp, easy-to-read document signals professionalism and increases the likelihood that a user will read to the final slide.
