## Definition

9:16 is the vertical video aspect ratio used for TikTok, Instagram Reels, YouTube Shorts, and Snapchat, measuring 9 units wide by 16 units tall.

## Extended Definition

The 9:16 aspect ratio fills the entire screen on mobile phones held in portrait orientation. It became the dominant format for short-form social video with the rise of TikTok in 2020. Standard resolution is 1080x1920 pixels. Content designed for 9:16 places key elements in the center of the frame to avoid safe zone issues (platform UI overlaps at top and bottom). When creating 9:16 content from horizontal footage, creators use reframing tools that track subjects and crop intelligently. BlitzReels exports in 9:16 by default for short-form workflows and supports safe zone preview overlays.
