Ring Size Guide

To ensure a well-fitting ring, it’s important to find your ring size by using a thin strip of paper or string and measuring your hand’s circumference.

If you’re unsure of your ring size, we recommend measuring several times. If your size falls between two numbers, always choose the larger size.

Given below is another chart, which can also be used in determining ring size. The chart lists out the inner diameter of rings in millimetres. This chart is normally used for double checking the results from the usual paper method. Apart from this, you can also make use of the ring you wear daily and cross-check the same with the chart given below.
