How to find out your ring size if you don't know it? 


Op. 1: DIAMETER Measurement:

  1. The easiest way to find the right size is to measure the diameter (from the inside) of a ring that fits you.
  2. Then check that DIAMETER equivalency to NILA BLISS size (which is the same as the USA & CANADA sizes)

 

Op. 2: CIRCUMFERENCE Measurement:

  1. Wrap a thin piece of paper (or a string) around the finger you are measuring for the size.  
  2. Mark where the end of that piece of paper meets the other side. 
  3. Measure the length to the mark, this will tel you the circumference size.
  4. Then check that Circumference equivalency to the NILA BLISS size (which is the same as the USA & CANADA sizes)

 

For ADJUSTABLE rings:

  • These normally come in a diameter of 17 mm – Size 6 1/2, and you will be able to adapt it to your size going up or down from there.

 

TIPS:

  • Remember that in summer or hot weather, your fingers can widen up.
