How Do I Find My Ring Size?

If you're unsure of how your ring size translates to US ring sizes, or if you simply don't know your ring size, you've come to the right place! We have a helpful little chart just for you.

Simply take a piece of string, yarn, or ribbon, and wrap it once around where you would like to wear your ring. Measure the amount of material that went around your finger on a ruler in millimeters. Match up the millimeters and look for your corresponding ring size. It's that easy. 

If this is a gift, and you're unsure of the receiver's ring size, note that the most common ring sizes are 6, 6.5, 7, 7.5, and 8. We offer a free one time ring resizing even if you get it wrong.
