Additional Tips for the Best Fit

Allow adequate area for your knuckle to fit.
Keep in mind that various fingers on the same and opposite hands may have different sizes.
Take a measurement of the finger where the ring will be worn.
Take your finger measurement at the end of the day, when it is most likely to be the longest.
Order a size up (larger) if you are in-between sizes.
If your finger is cold or hot, make sure it is at room temperature.
Take two different measurements and choose a size in the middle of your knuckle that is substantially larger than your finger's base. A ring should fit perfectly over your knuckle but must not be too loose; otherwise, it will keep moving around your finger.
