You can measure your ring size at home in two simple ways:

  1. Cut a strip of paper and wrap it around your finger. A paper ring is formed. Take out the paper ring and measure its diameter on a scale in mm.
  2. Cut a strip of paper and wrap it around your finger. Mark the end where it meets. Open the paper strip and measure it on a scale in mm starting from the first end to the point you marked. It is the circumference. 

Now, follow the chart and choose the right size. If you are confused between two sizes then go for the next size.
