How can I tell my ring size?
Go get it sized
You can go to any jeweler and ask them.
Most jewelers should size you for free, or there are paper dozers you can print from the internet to use. Or you could go to an accessory store and try on rings in your approximate size to find out just for fun
Wal-Mart (go to jeweler center they have a thing they can masher you finger:)
Try on a ring then look at the size and if it fits then its your size
