Ring Size Guide

Finding your ring size and getting it right can be quite daunting, but it's actually really straightforward. Below, I have put together a small guide to help determine the correct ring size, whether it be for yourself or as a gift to a loved one.

Below are some tips when measuring your ring size:

  • Don't measure you ring size when your hands are cold. Temperature and physical activity can effect the size of your fingers.
  • Please note that wider rings bands require a little more wiggle room, because of this you may need to choose a slightly larger size.

Visit a Local Jeweller

This is the most accurate way to determine your ring size and it is very likely to be a free service.

Order a Ring Sizer

You can purchase a ring sizer from my website here for a very small cost. Your finger size can fluctuate over years so they're handy to keep for peace of mind when ordering new rings. You can also pass them onto family member and friends if they're unsure of their ring size too.
