We understand the importance of finding the perfect ring size, which is why we have created a guidance tool to assist you in selecting the right size for your ring:

Yoreh rings use US ring sizes 4 to 15. You can measure at home in a couple of minutes.

1. Take a ring that fits the finger you want, worn on that hand.
2. Measure the inside diameter across the middle, in millimeters.
3. Match that diameter to a US size (for example, 16.5 mm is about a US 6, 17.3 mm about a US 7, 18.1 mm about a US 8).
4. If you are between sizes, size up. Fingers swell slightly through the day.

1. Wrap a thin strip of paper snugly around the base of the finger.
2. Mark where the paper overlaps, then lay it flat and measure the length in millimeters. This is the circumference.
3. Divide the circumference by 3.14 to get the diameter, then match to a US size as above.
4. Measure at the end of the day, when fingers are largest, and size up if between sizes.

1. A Yoreh smart ring jacket is sized to the smart ring it goes over, not your bare finger.
2. Order the jacket in the same US size as the Oura or RingConn you already wear.
3. Select your smart ring model (Oura Gen 3, 4, 5, Ceramic, or RingConn 2 or 3) so the jacket is cast to the right profile.
4. If you do not know your Oura size, check the size on your Oura sizing kit or in the Oura app before ordering.

If you are unsure, email hello@yoreh.co with the finger or the smart ring you are sizing for, and Yoreh will help you choose.
