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.
