"Normal" sizes for magnets

[LoveDisneyx4]

This might be silly to ask but what's the normal size of most of the magnets the DISigners make? I know that they can be adjusted but most seem to want to print out normal paper size (8x11ish)?? What's normal for Minnie/Mickey head with name inside? The porthole ones? The Mickey head with smaller Minnie/Mickey heads around the outside area? Name fills? I don't want them all to be 8x11 size. Is it personal preference? Just as long a the names can be read?
