Measure your finger
You will need a piece of string to wrap around your finger, then follow these steps.
The number closest to the pen mark is the circumference of the ring.
Your finger size will expand and change throughout the day depending on the elements such as weather. It is a good idea to measure in the morning and again in the afternoon to determine the best size. The fit should be comfortable but not be able to slide off the finger too easily. Check your length against this chart.
