Do you really think this looks good?
The
maximum dimensions should be square to harm both Legacy and Standard as little as possible. Or at least less then 240px length to be a bit more fair towards Standard O.o There is no one saying your
own avatar needs to fill out the maximum dimensions. If you want a non-square avatar, by all means make it a bit less tall or a bit less wide.
Or just get rid of one of the postbit style options. Risk upsetting a huge number of people, but get rid of this particular problem.
Of course, perhaps I am the only member with a true dislike for big avatars, in that case I'll just have to use Modern (thanks for making me realize that btw!) or live with it I guess ;p
