Ring Size Guide

All our ring sizes are in HK sizing. Ring sizes may fit differently depending on the thickness of the band and the temperature of your fingers throughout the day. You may size up slightly (half size) for thicker bands for more comfort if you wish.

 

How do I measure my ring size?

We recommend getting accurately sized at a local jewellery store. However, if you are unable to, there are alternative ways to find out your ring size.

If you already own a ring that fits comfortably on the intended finger, you can measure the inner diameter of this ring in millimetres. We can use this measurement for made to order and custom rings. Additionally, please refer to the chart below to find out the corresponding international ring size conversions.

 

 

If you do not have a ring to measure from, use a piece of semi-stiff paper/card similar to the width of the ring you want to purchase. Use it to wrap around your finger and then tape the card together and try it on like a real ring. Make sure it is secure but not too loose and ensure it can fit over your knuckle. This will give you a fairly accurate measurement that you can then compare with the information in the chart given below. Do note that finger sizes change throughout the day according to temperature changes, so do this a few times to eliminate incorrect measurements. Please note that though this is only accurate to a certain extent, and the best way is still to get measured professionally.

Alternatively, consider purchasing a reusable ring sizer online. These are fairly inexpensive and can be kept for future use.
