Aspect Ratio
The width-to-height proportion of a video, like 16:9 (landscape), 9:16 (vertical) or 1:1 (square).
Aspect ratio describes a frame's shape. Landscape 16:9 suits YouTube and desktop; 9:16 fills a phone screen for TikTok, Reels and Shorts; 1:1 and 4:5 are square and portrait formats that perform well in feeds. Posting the wrong ratio wastes screen space and hurts reach.
Repurposing a horizontal video for short-form means reframing it to 9:16 without cropping out the subject.
