If you don't know your ring size, there are several ways you can measure it.
The easiest is to take a measuring tape and measure the circumference of your finger in millimeters, which will be equal to your ring size. That is if your finger measures 53mm all the way around, you use size 53.
It is important that your hands are not warmer or colder than they usually are. It does not take many fluctuations before the measurement can show either a size too large or a size too small in relation to the ring size.
You can also measure the diameter of a ring that already fits you and look in the table here to find your ring size.
