Quick help. avatar size problem

hey guys my avatar size is 310 by 100 but why does it show up so small?

because the maximum dimensions for a non-premium av is 160 x 64 (pixels).

the maximum file size for a non-premium av is approximately 19.5 kb.

oooooooooooo lol
how do you become premium ?

nvm i got it lol
thanks streak
