Find your ring size with our convenient Ring Sizer. All you have to do is wrap the sizer around the widest part of your finger, and pull it tight for accurate sizing!

  • Made of soft flexible plastic in black with gold foil numbers
  • Adjustable, reusable, easy to use, and very handy to have around
  • Measures US ring size from 1 - 17 in full and half sizes


Rings are created true to standard US sizing. For the best fit we suggest having your finger(s) sized. We offer a physical ring sizer as well! Alternatively, you may follow the steps below to find your best fit:

  1. Wrap a string around your finger where you'd like your ring to be or place the string across the inner diameter of a ring that fits you from end to end.
  2. Make sure that the string is pulled snug for the best accuracy
  3. Mark the spot where the string meets and measure with a ruler in millimeters (circumference) or measure the string's distance across the center of the ring (inner diameter)
  4. Use the circumference or inner diameter column in the chart below to find your size

        I’ve always wanted to know what my ring size is, and I’m a little shy about asking to get it sized. And I’ve always wanted rings to jewelry collection, so I’m glad I finally know my size to start buying.
