Video Aspect Ratio

Aspect ratio defines the proportional relationship between the video's width and height. Common aspect ratios include 16:9, 4:3, and 1:1.

Why do we test it?

Ensuring that the aspect ratio matches platform requirements is vital for preventing distorted visuals. An incorrect aspect ratio can result in ads being rejected or shown incorrectly on screens, affecting campaign performance.
