Please be aware that this is only a guide.  Visiting a local jewellery store and having your finger size measured will give you a fairly accurate idea but there is sometimes one or two finger sizes variance between different stores due to slight differences in measuring equipment and methods.  The width of the ring and how curved the inside surface is will also affect size accuracy.

A wider ring requires a bigger finger size than a narrower ring.  A comfort fit ring with a curved inside surface goes on easier so can be half a size smaller than a flatter profiled ring.  Ideally call to our store in person for the most accurate size.
