Choose a Size

All cuffs by Tobi Mozhna are made in a universal size for the right or left ear. We spent a long time balancing beautiful design with comfortable wear — and we’re confident we nailed it.

Ring sizes follow the Ukrainian scale and correspond to the inner diameter of your finger in millimeters. Here are a few ways to find your size:

1. Measure an existing ring. Use a ruler to find the inner diameter in millimeters. For easier measurement, place the ring on paper, trace the inside with a pen or pencil, then measure.
2. Wrap a piece of string around your finger, mark where it meets, and measure the length with a ruler. Divide the result by 3.14 — this gives your ring size in millimeters.
3. The average ring size for women is 16–17, for men 17–20.
4. Sizes increase in 0.5 mm increments, generally ranging from 14.5 to 23. The most popular sizes are 16–19. If you have any questions, feel free to reach out via the contact details on our website or through our social media.
