Ring Sizing - International Conversion Chart and Measuring Tool

Finding or measuring your ring size

As with clothes, garments and shoes, rings also have sizing and unfortunately, this sizing exists in more than one scale which differs between countries.
There are a number of ways to find out your or your partners ring size:

  1. Go to a local jeweler and ask to measure your finger.  Local jewelers have special measurement rings which you can slide on your finger and feel which size is the most comfortable. This is the recommended method and the most accurate one.
  2. Print out our special ring sizing chart and wrap it around your finger to find out your size.  Make sure the PDF is not resized when printing.
  3. Take a ring you currently have that fits well and measure its inside diameter or put it on our ring sizing chart to see to which size it will fit best.

Our ring chart can be downloaded from here:
