AuraSync Sizing Guide
Accuracy is paramount for the R6 Smart Ring. Due to the sophisticated internal sensors, an incorrect size will compromise the accuracy of your health data. Please follow these steps carefully to ensure the best performance.
1. The Right Finger, The Right Time
-
Placement: The AuraSync R6 is designed to be worn on the index, middle, or ring finger for optimal reading.
-
Optimal Measurement Time: Measure your finger size at night when your fingers are usually at their largest. Avoid measuring immediately after exercise or when hands are very cold, as this can affect the size.
-
Knuckle Check: Ensure the measurement allows the ring to slide over your largest knuckle.
2. The Simple Measurement Method (Circumference)
This method requires a simple strip of paper or a flexible tailor's tape measure.
-
Prepare: Cut a thin strip of paper (approx. 1/4 inch wide) or use a piece of string.
-
Wrap: Wrap the paper or string snugly around the base of the finger you intend to wear the AuraSync R6 on.
-
Mark: Mark the exact spot where the paper/string overlaps itself.
-
Measure: Use a ruler to measure the length of the paper/string from the end to the mark. This is your Circumference in millimeters (mm).
-
Consult the Chart: Match your final Circumference measurement to the chart below to find your US Size.
