Not sure about your ring size? No worries, we got you!

Precisely measure sizes 1 to 17 with our ring sizer. Here is how. Ring Sizer only measures whole and half sizes - not quarter sizes. Delivered to you in 3-6 business days in a USPS envelope, tracking not included.

Each ring sizer comes with a sizing card to help you determine what size you need for piercings, hoops, nose rings, septums, and ring band widths. 

Are you outside the US and don't want to pay for international shipping? Give a try to our DIY sizing guide here, but note that it will not be as accurate as using this nifty ring sizer.
