Easy Size SelectionTo find your ideal fit, simply wrap a piece of thin string around the base of your finger. Mark the meeting point, then measure that length with a ruler to determine your finger's circumference. Match your measurement to the correct smart ring size. We suggest selecting one size smaller than your measurement, as the string method often provides a looser fit. Choosing one size down helps avoid the smart ring from slipping off.
