1. Wrap a strip or ribbon that doesn't stretch around your finger where you’d like your ring to be.

2. Make sure that the strip or ribbon is pulled snug to your finger, the tighter the better, to find your best fit.

3. With a pencil, mark the spot where the strip or ribbon meets.

4. Measure the length of the strip or ribbon with a ruler.

5. Use the below chart to determine your ring size.
