For optimal performance and accuracy, it is recommended to wear the COLMI R06 Smart Ring on your index finger. The middle and ring fingers are also suitable. Avoid fingers that are significantly narrower than the knuckles at the base, as this may affect sensor contact and data accuracy.

How to Measure Your Finger Size:
- STEP 1: Take a long non-elastic rope or paper, and wrap it around your finger.
- STEP 2: Make the rope or paper fit closely to your finger to avoid being too loose or too tight, which may cause size deviation.
- STEP 3: Mark the junction part on the rope or paper.
- STEP 4: Lay the rope or paper flat, and measure the length. It is recommended to measure multiple times for more accurate data.
