Ring Sizing Guide

How to get your finger size

  1. Measure the diameter (mm) of a ring that fits the desired finger
  2. Use the Ring Sizing Chart below to locate your size

If your do not have a ring, measure the desired finger

  1. Wrap a strip of paper around your finger, just above the knuckle, and mark the point at which the two ends meet
  2. Measure the paper from mark to mark to find your ring circumference (mm)
  3. Use the Ring Sizing Chart below to locate your size


Most ladies rings are an average size M.

Most Men's rings are an average size U.

We offer one FREE resizing serivce (within 2 full sizes) when you purchase a ring from us. You must return the ring within 10 days of the original shipment date. You will also be responsible for any related shipping cost.

If you require a resizing of more than 2 full sizes, or you are beyond the free resizing period, we would still be happy to perform the resize for you at an additional cost.

Rings can take approx five days for resizing.

If the ring is for a gift we recommend sizing after it is presented where we can then measure the finger and arrange the correct size.

If any piece has been altered in any way by a jeweller other than Jack Dylan Jewellers, your warranty is no longer valid.

It is our recommendation that each piece be regularly maintained and checked once a year by a service professional.
