Ring size guide

To measure your ring size, you can measure either your finger or an existing ring you have.

How to measure your ring size:

  1. Take a short piece of string and wrap the string around your finger or the inside diameter of your ring. Make sure you do not wrap the string too tightly to get an accurate result.
  2. Mark where the string overlaps. Lie the string flat besides a ruler or measuring tape and measure the string.
  3. Note the measurement and use the chart below to determine your size.

Please note, in our Amber Lynx jewellery website we use the US ring size.
