Not sure?

Try on #1: Measure a ring you wear

The easier way to find out your ring size is by measuring a ring you already have. If the measure falls between two sizes, always choose the larger size.

We advice you not to consider the size of the ring edges or its thickness to evaluate your right size.

Still not sure?

Try one #2: Measure your finger(s)

Get a strip of paper with 1,5 to 2cm width, wrap it around the base of your finger and use a pen to mark where the tape touches the other end. Using a ruler measure the distance between the ends and you'll get the ideal size for you ring size.

Specialist's note: take more than one measurement with this method as it may vary depending on the time of the day or weather conditions.
