How to Measure

Please see the diagram below and follow the steps to help measure the size of your fingers. This method of measurement will measure the circumference.


  1. Cut a thin strip of paper or a piece of string several centimetres long.
  2. Wrap it around the finger where you would want to wear your ring.
  3. Where the two sides of the paper/string meet mark it with a pen.
  4. Then lay this measurement down next to a ruler and measure in millimetres the length between the two pen marks.
  5. Once you have this circumference measurement in millimetres use the Ring Size Chart below to find out what size you are according to the country sizes.

Note: Please ensure the strip is wrapped around in a comfortable fitting, do not tighten it too hard.

Tip: You should measure your fingers in your normal climate or when the climate is higher as this is when your fingers are most swollen, this will prevent you from choosing a ring that is too small in size.

Note: The sizes used on Mirror Bella are in US and UK measurements.
