How do I measure my finger for a ring? This page will help you find your ring size by using an existing ring and our printable ring sizer. 

To ensure the correct ring size, we have some helpful advice for you:

• Find a ring that fits your finger perfectly. Keep in mind that the fingers on your dominant hand tend to larger than on your non-dominant hand.
• Pay attention to temperature when measuring a finger size. Fingers are sensitive to heat; usually smaller in the winter and larger in the heat of summer or after exercise.
• Please note that a ring size may depend on the design of a ring; a wide ring may require a larger size, therefore, order one size larger than you would for a narrow ring.
• If your size is between two sizes, you should choose the larger of the two.

If you do now have access to a printer you can take a ruler or a caliper and measure the inside diameter of your existing ring.
