Tips for finding your ring size: 
Measure your finger in warm temperatures at the end of the day.
When considering a wide band, move up a size from your measurement, for comfort’s sake.
Different countries have different ring-size systems. All sizes listed here are standard American sizes. The average woman’s ring size is about 6. 
Your ring size will be about half a size larger on your primary hand (i.e., the hand you write with).
