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. The average man’s ring size is about 10.

Your ring size will be about half a size larger on your primary hand (i.e., the hand you write with).
