To find out your ring size wrap a piece of string, or a narrow strip of paper, around the base of the finger you want to measure. Make sure you can slide the string, or paper, easily over your knuckle.
Use a pen to mark where the end of the string meets the string wrapped around the finger. This bit might be easier if you get someone to help you.
Using a ruler measure the length of the string from the starting point to the pen mark in millimetres.
Check the measurement against the chart below to find your ring size.
Where two sizes are given in the chart below, such as P-Q, this corresponds to a finger size that falls between two meansurements, in this example between 56.23mm and 57.49mm.
The best time of day to measure your fingers is at the end of the day, because then they are at their biggest. Your fingers are at their smallest when they are cold so try to avoid measuring them at that time.
