Image Aspect Ratio

The aspect ratio defines the proportional relationship between the width and height of the image. Common ratios include 1:1, 16:9, and 4:3.

Why do we test it?

Ensuring the correct aspect ratio is important for maintaining visual consistency across different devices and formats. A distorted aspect ratio can make an ad look unprofessional, reducing its effectiveness. Keeping a correct ratio guarantees that the ad displays as intended, regardless of where it's viewed, ensuring optimal brand representation.
