How to Measure Your Ring Size
There are several simple ways to find your ring size.
Option 1: Measure a Ring You Already Own
If you already have a ring that fits comfortably on the finger you plan to wear your new ring on, this is one of the easiest and most accurate methods.
- Place the ring on a ruler.
- Measure the inside diameter from one inner edge to the other, excluding the metal.
- Compare your measurement with the Inside Diameter column in our ring size chart above.
- If your measurement falls between two sizes, we recommend choosing the larger size.
Option 2: Measure Your Finger
If you do not have a ring to measure, you can use a strip of paper, string or dental floss.
- Wrap it comfortably around the base of your finger.
- Mark the point where the ends overlap.
- Lay it flat and measure the length in millimetres using a ruler.
- Compare the measurement with the Circumference column in our ring size chart.
- If your measurement falls between two sizes, we recommend choosing the larger size.
