Ring Size Guide
Go to a Jewellery Store
Get your ring sized (in HK size) by any jewellery store for free in person. This is the most reliable method and will ensure that your rings arrive as the perfect fit. Remember to get the HK size.
Use the Inner Diameter of Your Existing Ring
Step 1: To find out your ring size, take a ruler and measure it with the largest inner diameter of your ring.
Step 2: Using the table below, match the diameter of the ring to your ring size. If your ring size is in between sizes, choose the one nearer to your measurement. For example, if the inner diameter of the ring is 15.6mm, it is between size HK 10 and HK 11. Since 15.6mm is closer to 15.5cm, pick HK 10.
Using string or paper
Step 1: Wrap a string or paper of your choice around the base of the finger. Mark on the string or paper where they intersect with a marker or pen
Step 2. Unwind the paper or string and measure the distance between the 2 marks in millimeters (mm).
