If you don’t know how to measure your ring size just follow these steps:

1. Wrap a piece of string or paper around the base of your finger.
2. Mark where the ends meet.
3. Measure the length in millimeters (mm).
4. Find your ring size on the chart. If your measurement falls in between two sizes, it's recommended to choose the larger size for a comfortable fit. For example, if your measurement is 59mm, it corresponds to size 9, but if it's 61mm, it's best to select size 10.
