How to know your ring size

One of the issues that scares you when buying a ring online is to make sure it fits you!
Although we offer free returns on rings, we want you to get it right, and be able to start enjoying your Rio Design ring as soon as you get it.

So, here are two different ways you can measure your ring:

1- Measure the Diameter of a ring you have and fits you well

With the use of a ruler or a measuring tape, measure the inside  diameter of the ring. You should get the widest part of the ring, as shown in the figure 1.

Select a ring that fits you well. As shown in the picture, insert a small piece of  paper into your ring, rolled in a way that it feels all the inside space in the ring. Mark with a pen or marker where the roll overlaps the edge of paper.
