STRIKE GO
Size guide
Measure a ring you already own
You’ll need a ring that fits the intended finger and a ruler.
- Measure straight across the inside of the ring, from inner edge to inner edge. Do not include the ring’s walls.
- Find that inside diameter in millimetres in the chart below.
Measure your finger
You’ll need paper or string, a ruler, a pen and scissors.
- Cut a strip long enough to wrap around your finger.
- Wrap it around the base of the finger where the ring will sit.
- Mark where the ends overlap, then lay the strip flat.
- Measure to the mark in millimetres. This is your circumference; match it to the chart.
Use the STRIKE Go conversion chart below. Available sizes depend on the ring model.
