Size Guide

at aiza objects, our rings are available in half sizes (15.5, 16, 16.5, etc.). if you require a specific size, please contact us and we will be happy to create a custom fit for you.

we recommend measuring your ring size using one of two methods: measure the inside of an existing ring and refer to the internal diameter (mm) column, or measure your finger with string or paper and use the finger circumference (mm) column.

MEASURING TIPS

  1. measure at the end of the day in a room-temperature room for best accuracy.
  2. don’t pull the paper too tightly around your finger.
  3. if you’re between sizes, choose the larger one.
