If you already have a ring that fits you, measure the inside diameter and choose the right size from the list.
If you don't have a ring, wrap a string around your fingers and mark the points where they meet. Now you have the circumference of your finger - choose the right size from the list.
For women, the most common size is 8.
For men, the most common size is 9.
(Size one up if you are unsure).
