How to find your ring size.

Measure the Diameter:


If you already own a ring that fits perfectly, you can measure this to find your perfect ring size. To do this, measure by popping the ring on to a ruler and measure the inner diameter of your own ring, make sure you are measuring the interal diameter so the space you can see through the inside of the ring. Use this measurement to compare against the ‘diameter’ in our table to find your closest fit.


OR


Measure the Circumference:


If you would prefer to measure using a different method, for example if you cannot find a ring to measure the diameter of, you can instead measure the circumference of your finger.  You’ll need a piece of string a pen and a ruler to measure this, the circumference, is the outer measurement all the way around your finger,
 

  1. Find a piece of string or strip of paper no wider than about centimeter.
  2. Wrap it around the base of the appropriate finger.
  3. Use a pen to mark the point on the string/paper where it overlaps, forming a complete circle.
  4. With a ruler, measure the length from the starting end of the string/paper to the pen mark.
Once you have found your measurement, this is the circumference of your finger. You can compare this measurement to the ‘circumference’ row in our table to find your closest fit.
