Sizing Guide
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:
- 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.
- Make sure that the string is pulled snug for the best accuracy
- 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)
- Use the circumference or inner diameter column in the chart below to find your size

My fingers change sizes depending if I'm hot or cold, haha. Having my own ring sizer is perfect!
