Size guide
Finding Your Ring Size
Our rings are offered in EU/ISO sizes. The EU size is simply the inner circumference of the ring in millimetres.
- Measure at home: Wrap a thin strip of paper or a piece of string snugly (not tight) around the base of your finger. Mark where the ends meet, then lay it flat and measure the length in millimetres — this is your finger's circumference, which equals your EU ring size.
- Timing matters: Measure at the end of the day, when fingers are at their largest. Cold fingers measure smaller.
- Between two sizes?: Always choose the larger one. For wide band designs, we recommend going up half a size.
