4 Ways to Find Your Size
4 Ways to Find Your Oura Ring Size
1_Visit a jewelry store
Pop into a jewelry store near you and try on their standard wide-band US ring sizers to find your size.
If you're not in the US, you can use this conversion chart to convert US ring sizes to international ring sizes. Please note that the Oura ring is available only in full, not half sizes.
2_Use your first Oura ring as a reference
If you have the first Oura ring, it's comfortable in the morning and you want to wear the new Oura ring on the same finger, you can order the same size.
Please note that the new Oura ring feels slightly smaller than the first Oura ring, even if they're the same ring size. If you're not quite sure, use one of the other 3 ways to find out.
