Measure your finger
- Use a flexible measuring tape or a piece of string.
- Wrap it around the finger where you’ll wear your ring. If you’re planning a stack, consider where on your finger the ring will sit. If you’re using string, mark the spot where the ends meet with a pen.
- Place the string on a flat surface and measure it with a ruler in millimeters. Compare the length to a size chart to find your ring size. If your measurement falls between sizes, choose the larger one for comfort.
Measure an existing ring
- Select a ring that already fits your finger comfortably.
- Measure the inside diameter of the ring in millimeters.
- Compare the measurement to the size chart and find the closest match. The inner edge of your ring should line up with the outer edge of the circle on the chart.
