Determining your ring size at home

If you have a ring that fits you comfortably, you can use a ruler to determine the inside diameter of the band and compare it to the chart bellow.  

Alternatively, you can follow the bellow method:

1. Cut a strip of paper and wrap it around your finger. Be sure it fits comfortably tight, not too loose nor too tight 
2. Mark the spot where the paper meets around the finger
3. Unwrap and measure the distance with a ruler; this will be the band's circumference

Please keep in mind this guide is not definitive and ring size can vary slightly due to swelling, time of day and season. The most accurate way to determine your size is to visit a local jewelry store and ask to be sized.
