LinkedIn Carousel Size: The Complete 2025 Guide

Getting the dimensions right for your LinkedIn carousel is crucial for a professional look. Here's everything you need to know:

Recommended Size: 1080 × 1080 pixels Square format works best on both desktop and mobile. FormaBit automatically generates all carousels at this size.

File Format: PDF LinkedIn accepts PDF files for carousel posts. Each page of the PDF becomes one slide. FormaBit exports directly in this format.

Maximum Slides: Up to 300 pages LinkedIn allows PDFs up to 300 pages, but we recommend 5-12 slides for optimal engagement. More than 15 slides tends to lose reader attention.

File Size: Up to 100MB LinkedIn's file size limit is generous. A typical FormaBit carousel is 2-5MB total.

Text Size Tips: - Headlines: 28-36px (FormaBit's default) - Body text: 16-18px - Keep text readable on mobile — avoid anything smaller than 14px
