Easy Size SelectionTo find your perfect fit, simply use a piece of thin string to wrap around the base of your finger. Mark where the string meets, then measure that length against a ruler to get your finger's circumference. Match your measurement with the correct smart ring size. We recommend choosing one size smaller than your measurement, as the string method tends to give a looser fit. Going one size down helps prevent the smart ring from slipping off.
