Check out the steps below to determine the size of your ring:
Take a string piece and wrap it around your finger's base.
Mark the string, with a point where the end meets, using a pen.
Measure the string with the help of a ruler.
For determining your ring size, look at the chart below to find your ring size by choosing the closest measurement.
How to Achieve Best Results?
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.
