Dimensions

The dimensions of an ad refer to its width and height in pixels. Every platform or publisher may require specific dimensions to ensure proper display.

Why do we test it?

Validating dimensions is crucial to ensure that your banner ad fits the allocated ad space without distortion or cropping. Incorrect dimensions can result in poorly displayed ads that hurt engagement. Moreover, adhering to standard dimensions allows for compatibility across various platforms and devices, ensuring that the ad reaches the intended audience effectively.
