At PINKBOX, our rings are measured in HK sizes. If you know your ring size, you can simply use the table to convert between the various popular ring size to the HK size.

If you need to find your correct ring size, please follow these easy steps:

1. wrap a piece of paper or string around your finger, mark the point where the two ends overlaps.

2. Measure the length of the string or paper against a ruler to obtain the circumference.

3. Divide the result by 3.14 to get the diameter of your finger

4. Look up the chart to obtain your correct ring size.
