How to Measure Your Finger Size
A proper fit is important for comfortable daily wear and accurate sensor readings.
Follow these steps to measure your finger circumference:
1. Prepare a strip of paper or a piece of non-stretchable string.
2. Wrap it snugly around the base of the finger where you plan to wear the ring. The index finger is recommended for optimal sensor performance; the middle or ring finger may also be used.
3. Mark where the paper or string overlaps, making sure it is neither too tight nor too loose.
4. Lay it flat and measure the length from the end to the mark with a ruler. This is your finger circumference.
5. Compare the measurement with the Elenva Gen1 Size Chart below to find the appropriate ring size.
For best results, measure at room temperature and avoid measuring immediately after exercise or when your fingers are unusually cold or swollen.
