Ring Sizing by Remote Control (using the Ring Sizing Chart)

Finger Rings are by far the most popular of all jewelry (“jewellery“ As it is spelled in original English) terms.

Finger Rings are just about as old as history. People have used them for everything from identifying themselves as a member of a club, a school, a university, or as readers of the Phantom comic. (who could forget the skull and crossbones Phantom Ring)

But nothing that rings have been used for could compare with the symbolism they represent in expressing romantic feelings between man and woman, boy or girl.

Nowadays with the convenience of ordering online, a problem presents itself. How do you find out the correct size ring to order so that your gift will fit the finger of the wearer?

How Can You Find Out The Ring Size, and Still Keep the Ring Gift A Secret?

Often guys, who buy gifts for girls, don’t want to let them know whats coming. They want it to be a surprise. Particularly if it’s a marriage proposal. So how do you find out the size of her finger without letting her (or him) know?. If the girl is buying a ring for her guy, how does SHE find out too?

The Ring finger wedding ring is the second from the little finger, in case you didn’t know. It does vary from one nation to another but in most Western Countries it’s on the left hand. In Germany the wedding ring band starts off on the left hand for engagement then is transferred to the right hand to stand for marriage.

As you can see on the ring size chart, the sizing system also varies between countries although the US size is becoming the standard, like the USD.

It must be said first of course that if you have a ring finger engagement ring with marriage in mind, it would be wise to discuss the details with the receiver of the ring to make sure it fits his or her preferences and that it is sized properly.

You can do this by sifting through jewelry books or looking in shop windows, or, as is becoming more popular, type in ‘jewelry designs’ or ‘ring designs’ or maybe be a bit adventurous and look for something different.

Nearly everyone uses diamonds for engagement rings but why not look at something a bit more interesting such as opals, sapphires, rubies, etc. But then, we are getting off the track. How do you find the right ring size?

Usually, the first thing you think of is to ask the person’s mother or close friend if she knows the right size. If she doesn’t, maybe she can ask the close friend to ‘borrow’ one of the rings and try it on their own finger, carefully making a mark to show where it fitted well.

Then later go to a jeweler and get the finger sized to that mark. This could even be done in front of the person just by making out they are interested in the ring and asking if they could try it on. Just use a bit of initiative in this. If you ask someone to do this, better make sure you remind them that it’s a secret.

You could of course take the ring itself to a jeweler for ring sizing if you can do it without suspicion, then compare that information with the opal ring sizing chart.

You could also find something that is tapered, like a candle, and slip the ring over it and make a mark. Then get the candle mark sized by a jeweler and compare it with the ring size chart.

Can all rings be re-sized? Most can, but signet rings can be a problem if there is too much gold and silver on the edge of the ring where it tapers down your finger. (This is called the ‘shoulder’ of the ring.

Having said that, most skilled jewelers can size these rings as well, using the information in the ring sizing chart. The only problem rings are those that have inlaid stones such as opal or turquoise that are inlaid into the shank itself.

Ring sizing jewelry like this is almost impossible because the stretching of the ring can cause the stones to crack. Check with your opal or turquoise supplier before purchasing these rings. Make sure they are the correct size at the time of buying.

  1. Hello friends, Could you help me find the size of a ring with a circumference of 8 centimeters and a half, I still don't know what the size is for that measurement..

    1. 8 1/2 es el sistema americano de dimensionamiento de anillos. Es mejor si obtiene una regla y mide a través del anillo y me dice el diámetro y calcularé el tamaño correcto. Mira el ejemplo debajo de la tabla. pero por favor mire la misma página en español. También dime los números de los anillos que te interesan y te diré si son del tamaño correcto y si se puede dimensionar para adaptarse. Espero que esta traducción sea fácil de entender. Intenté enviarte un correo electrónico pero rebotó. Por favor confirme su dirección de correo electrónico

  2. متاسفم، من نمی فهمم. من دوستان ایرانی من بپرسید به ترجمه برای من. شاید او به شما به طور مستقیم صحبت کنید.

    1. So sorry for not answering your question. somehow i didnt get it. you said the finger size was 8mm this does not sound right. Maybe she meant 8 which is a USA finger size. In the UK, this would be P 1/2 but if you are from some part of Asia, it would be 4 1/2 in US size. hope that helps. Peter.
