Help changing my Avatar

Ok I have a pic selected that I want to change it to. When I crop it to where I want it to display and all and hit submit it keeps saying too low area… no clue how to get it to get that to go away.

what your little tutorial shows me is exactly what I am doing

Edit: Nvm I got it finally the picture I was trying to use apparently was messed up or something found a different one and it worked xD
