Vertical video ads

Vertical video ads are video ads displayed in a vertical way that fulfill the screen of a mobile device.

Vertical video has a 9:16 aspect ratio, while landscape video has a 16:9 aspect ratio and square video has a 1:1 aspect ratio. Almost all videos are landscape, as they were optimized for movies and television.

Since last year, vertical video ads are available on YouTube. Vertical video ads are also available on Instagram and Facebook.
