Size Chart
To determine your ring size, measure your finger at the end of the day when it is neither hot nor cold. Measure the finger of the hand on which you intend to wear the ring. Wrap a strip of paper around the finger, ensuring that you leave enough room to slide the ring over your knuckle. Mark the spot where the paper strip meets and use a ruler to measure the length in millimeters (mm). This is the circumference of your finger, which corresponds to EU ring sizing. Choose your ring size based on the chart below. If you are between sizes, opt for the larger size.
