Hi Roman,
Thank you for contacting us. Please note that this forum can only answer Mobile Ads SDK setup and support. You are asking a question about ad sizing. I can refer you to
AdManager Support and here's a
page that may help you find the right ad sizes for your needs, and another
page that describes expandable ads that proportionally grow to fit their space. Of course, if you have trouble implementing these ads on the app side then this forum is the place to turn to.
Regards,
Aryeh Baker
