Excellent question! The dimensions of the digital ads are not customizable because we are following the Interactive Advertising Bureau (IAB) suggested dimensions for digital advertising. 

These standard dimensions allow flytedesk digital to serve ads on your website. 

Note: If you want to sell custom digital ads, you can use our curated "In-House Digital" medium and customize your digital offering. Please remember that flytedesk digital will not be able to serve customized digital ads.
