gauged both my holes in both ears myself. had 10's in the top holes and double 0s in the bottom holes. i like them while i was into it considering i had them since i was 15 up until like about a year and a half ago i just took them out one day for no reason. haven't wore any since. even tho my top holes haven't shrunk a bit and my bottoms are around a 4 maybe a little smaller.
