Note: For the best results, please use a thin, non-stretchy material, such as a piece of regular sewing thread or a thin strip of paper, as these closely mimic the fit of a ring. Thicker materials, like a shoelace, may lead to an inaccurate measurement because they can add extra bulk around your finger.
To find your correct ring size for the Bionic™ Ring, use a simple piece of string to measure your finger. Here’s how you can do it:
1: Wrap the String: Take a piece of non-stretchy string or a strip of paper and wrap it comfortably around the base of your finger, where the ring will sit. Make sure it’s snug but not too tight.
2: Mark the Spot: Mark where the string overlaps with a pen or marker.
3 : Measure the Length: Lay the string flat and measure the length from the end to the marked point in millimeters using a ruler.
4: Compare to Our Chart: Visit the product page on our website and refer to the US ring size chart. Match your measurement (in millimeters) to the corresponding US ring size listed there.
For the most accurate fit, measure your finger at the end of the day when it’s likely to be at its largest. If you’re between sizes, we suggest sizing up for comfort. If you have any trouble finding the chart or determining your size, feel free to share your measurement with us, and we’ll help you match it to the correct ring size!
