## Definition

16:9 means 16 units wide for every 9 units high: a horizontal, widescreen shape. Common pixel sizes are 1280 × 720, 1920 × 1080 and 3840 × 2160. It describes proportions, not one resolution; 9:16 reverses the shape for vertical video.

## Extended Definition

Read dimensions as width × height. Dividing 16 by 9 gives approximately 1.78, so a 16:9 frame is about 1.78 times as wide as it is tall. Both 1920 × 1080 and 3840 × 2160 have this shape, but the latter contains four times as many pixels. A larger export cannot recover detail missing from the recording.

For a webinar or two-person podcast, keep a widescreen master when slides or both speakers need the full width. To make a vertical excerpt, crop around the subject or fit the full recording inside a portrait canvas. A crop removes the sides; fitting preserves the source with space above and below. Review moving speakers, slide text and captions before exporting rather than stretching the image to fill the frame.
