Ring Size Guide
A simple 3-step method to check your ring size:
- Take a ring that is already in your size and put it on a white paper.
- Draw the inner circle of it on the paper.
- Then, check the diameter of it and use the table below to find your ring size.
When choosing a wide-fit ring, such as this design, we recommend sizing up either a half size or a full size.
