Q1: How do I size a CUDIS Ring?
To ensure the most accurate data and a comfortable fit, we recommend using the CUDIS Sizing Kit. We suggest wearing the plastic sizer on your preferred finger to account for natural swelling throughout the day.

[Contact Support: support@cudis.xyz]MEASURE YOUR FINGER
1.
Use a flexible measuring tape or length of string. Wrap it around the finger you'll wear your ring on - if you're creating a ring stack, consider where on your finger the ring will sit. If using string, mark the point on the string where the ends meet with a pen.
2.
Lay the string on a flat surface and use a ruler to measure the length (in inches or millimeters) up to the mark. Compare your measurement to the size chart above to determine your ring size. If you are between sizes, opt for the larger size.
MEASURE AN EXISTING RING
A helpful method if you're surprising someone with a gift or treating yourself.
Choose a ring that already fits your finger well.
Measure the interior diameter of the ring in millimeters (mm).
Use the measurement chart above to match the size of your ring to the closest size in mm. The interior of the ring should align with the outer edge of the circle.
FAQS
Q2: How long does the battery last?
A fully charged ring lasts up to 10 days, allowing for continuous day-and-night tracking. Battery life may vary slightly depending on your usage of specific features and the age of the device.
Q3: How do I swap colors on the CUDIS Ring?
Just slide off the existing rubber band and snap a new color into place. Keep in mind the ring comes standard with only a black band, and additional colors require a separate accessory box purchase.
