A health lab on your finger, with a subscription-free experience and premium features like blood pressure and glucose trend coming soon. Circular Ring sizes are different from standard ring sizes. We recommend finding your size before purchasing your ring. Purchase our Circular Ring sizing kit to find your optimal size, then come back and order the right size. Sizing Tips: Circular Ring 2 is available in 9 sizes, from US 6 to US 14 (no half sizes). Ring sizes run about one half size above standard ring sizes. For example, if you normally wear a size 9, we recommend choosing a size 10. You can wear the Circular Ring 2 on any finger, but all four fingers aside from the thumb give the most accurate readings. The thumb still works but with less precision. The Circular ring is best worn on your non-dominant hand. Finger size changes during the day! Sizing is most accurate midday. The Circular logo of the ring should face the top of your finger, and the flat sensor part should face your palm. ‍Between Sizes? Choose the larger size but make sure it’s snug enough not to fall off. If you have large knuckles, choose the smallest size that slides over them comfortably.
