Envato Community Customization Options

So it looks like we can now customize our profiles in this new community site, but what are the proper specs? The Profile Background and User Card Background don’t specify the exact dimensions which I would find pretty useful. It says the default width that it will be, but not the height. Maybe I’m missing something, but does anyone know where to find this information?

I would also like to know about that. And also what is the difference between user card and profile background?

Still don’t know the specs.
