I like it middle, or somewhere between middle and top. At the bottom just looks odd to me.
was just about to say the exact same thing. (y) :thumbsup:Symbol should be half the height of the number and either slightly less than flush with the top or middle aligned, definetly not bottom. Generally, center the number without the symbol then add it. The number is dominant to the eye for balance (left to right). It will look out of balance if you center number(s) and symbol together. Every example above in the OP is out of balance.
