  4. Use the chart below to determine your E3 Ring size.
  5. When in doubt – go for the smaller size.

Here are some tips to make your ring size measurement more accurate:

  • Even if you know your UK ring size, remember that it was sized to fit over your knuckle. The E3 silicone ring is elastic and can easily stretch over your knuckle, therefor if your ring is bigger at the base of your finger go for a smaller silicone ring for a better fit.
