The following are the suggest sizes so that they will be displayed with proportions and appropriate sizes. SelBuk adjusts them when they are oversize, but it is recommended to fit them to the right size given. That is to keep proportions and do not show white backgrounds or any other color. If you want to use iPhone and iPad with different users, we suggest the iPad format, because in iPhone there is not much difference as it is in iPad.
