I'm designing the UI of a mobile game in Unity, playable in Portrait orientation on both phones and tablets, iOS and Android. I would like to place a banner ad at the bottom, possibly wide as the screen width. I need to know how much space will the banner occupy in height, to optimize the placement of UI elements without having them covered by the banner, and without leaving more empty space than needed.
Since there are many different screens, in terms of size, resolution, ppi and aspect ratio, is it possible to predict the height of the banner on all possible screens at a specific aspect ratio? Or at least the range of minimum and maximum possible height?
Thank you in advance for your help.
