Find your Luvoden size
Every Tidal Ring is listed in Australian sizing first, with the US equivalent alongside it. There are two easy ways to work out your size at home — you only need one of them.
Method 1 — measure a ring you own
- 1. Choose a ring that already fits the intended finger.
- 2. Measure the internal diameter from inside edge to inside edge in mm.
- 3. Match the measurement to the chart below.
Method 2 — measure your finger
- 1. Cut a narrow strip of paper about 6 mm wide.
- 2. Wrap it snugly around the base of your finger and mark the overlap.
- 3. Measure the marked length in mm — that's your circumference.
- 4. Divide the circumference by 3.14 to get the diameter, then use the chart.

- Between sizes? Choose the larger size if you prefer a more relaxed fit.
- Fingers change slightly through the day and with temperature. Measure in the afternoon, at a normal room temperature, for the most representative result.
