All rings are made in standard US sizes from 6 to 9. 

How to measure: 
1. Take a ring you already wear on the finger that you wish to wear your MIMO ring on. 
2. Using a ruler with mm measurement, measure the inner diameter of the ring across the centre of the ring opening. See diagram below.
3. Take that measurement in exact mm and locate which size it is closest to on our chart below. 
4. If you are in between sizes we recommend sizing up.
