How to Choose Your Size

1. Measure Your Finger Circumference
Here’s how:
  • Prepare a thin string or strip of paper.
  • Wrap the string or paper around the base of the finger where you plan to wear the Circul Ring.
  • Mark the point where the string overlaps.
  • Unwrap it and measure the length, then compare it with the Circul Ring size chart.
    2. Confirm Your Choice
    • Once you wear the Circul Ring, you should be able to bend your finger easily.
    • When moving your hand, the ring should not feel loose or slide off.
    • After wearing it for an extended period, there should be no noticeable indentations or discomfort on your finger.
    • Ensure it can easily pass over your knuckle but does not rotate freely at the base of your finger.


      Benefits of the Circul Ring's Adaptive Design

      1) Precision Fit：
      The Circul Ring features an adaptive design that replaces the traditional thirteen sizes with just three, ensuring optimal sensor contact with the skin. For example, when pregnant, a woman's fingers may swell, but the Circul Ring automatically adjusts to maintain comfort and data accuracy.
      2) All-Day Comfort：
      Utilizing FreeFit™ technology, the Circul Ring adjusts to fit your finger, providing unparalleled comfort whether you are active or resting. Fitness enthusiasts may experience temporary finger swelling during strength training, but the ring’s design ensures it won’t feel restrictive during workouts.
      3) Versatile Wear：
      One ring fits any finger, easily adapting to various life changes without missing any health data. For arthritis patients, the Circul Ring’s adaptive features allow them to wear it comfortably, even in discomfort, while still obtaining health monitoring data.
