Unsure about your QRNT Ring size? Purchase our QRNT Ring Sizing Kit.

QRNT Slim fits more snug due to raised sensors on the inside. Consider swelling and knuckle width when choosing your fit. QRNT Slim should be worn on the index, middle, or ring finger. It is most accurate when worn on the index finger of your non-dominant hand. We recommend sizing up from your usual ring size.
