9 16 Sizing Guide for Social Media Videos
Learn how to use the 9:16 vertical video format for social media, with sizing tips, platform guidelines, editing tools, and design best practices.
Understanding the 9:16 Aspect Ratio for Mobile Video
The 9:16 aspect ratio is a vertical video format where the width measures 9 units and the height measures 16 units. Unlike the traditional 16:9 landscape orientation, 9:16 is known as portrait orientation, making it ideal for mobile-first viewing experiences. As smartphones dominate content consumption, this format fills the entire vertical display, eliminating the need for users to rotate their devices and creating a more immersive experience from the first frame.

- It fully occupies vertical screen space on mobile devices.
- It matches the natural orientation of phone cameras.
- It creates a personal, direct feeling for viewers.
- It removes friction—no need to flip the phone to watch.
