Whether referring to wedding rings or rings designed to celebrate a special event in one's life, determining the size of this most important type of jewellery is crucial. There are many important reasons why the correct ring sizes must be obtained, not least concerning the security of your valuable jewellery, which can easily slip off a finger if sized incorrectly. Rings which are sized too modestly can lead to discomfort or an inability to be worn on the intended finger which, in the case of highly sentimental pieces such as wedding rings, can cause quite some upset.
The first step in sizing a ring is to take a real-life measurement of the finger of the client. The jeweller will utilise a stick with ring-sized markings, known as a ring sizer or mandrel, to make certain that the diameter of the ring is accurate. After the metal is cast and the details are added, it may once again be placed on this ring size guide to make certain that its circumference has not changed, it is therefore important that the correct fit is discerned from the very beginning of ring creation. A good example of a snug fit can be seen below.
Sizes are determined by two primary factors. These are the inside circumference and the inside diameter, the latter is concerned with the width of the interior space while the former "revolves" around the number of inches (or millimetres) which represent the circumference. These both serve as a general ring size guide.
Sizing conventions can vary around the world dependent on one's location. Regions such as the United States, France, Russia, Germany and Japan categorise their sizes differently. For the sake of this article, we will be briefly looking at the sizes associated with the United Kingdom.
For ease of reference, jewellers within the United Kingdom size rings (such as wedding rings) with an alphanumeric ring size chart. The smallest sizes start with the letter "A" and the widest diameters are associated with the letter "Z". In many cases, there are subcategories within each letter such as "A 1/2", "F 3/4" and "T 1/2" to further accommodate size variations. Please note that these measurements apply for both men and women. The upper range of diameters is normally occupied by males, while female fingers tend to fall within the lower end of the size spectrum. We will now take a look at some examples of the measurements that are commonly used by jewellers. A ring sizer will be familiar with these metrics.
It should be mentioned that the numerical measurements themselves are universal. It is only how these measurements are labelled on a ring size chart that will vary from region to region. To appreciate the sizes between two different rings, please observe the picture below:
There are instances when a couple decides to have their rings sized simultaneously. This is quite common when referring to wedding rings. Once the dimensions have been obtained, the jeweller can begin to fashion the ring in question. The time required to receive the finished product will naturally revolve around the artisan in question. As sizing a ring is an exact science, this is best entrusted to a professional, and ample time should be given to ensure the perfect fit.
