Ring fit guide
Our bands have a comfort-fitted inner, so they feel slightly looser than a flat band — order your true size.
Tap a row to select that size.
- Measure when your hands are at room temperature — not too warm, not too cold.
- Cold hands measure up to half a size smaller — avoid measuring in winter or after exercise.
- A wider band needs a slightly larger size: at 6mm and above, go up a half size.
