The best and most fool proof way to get your finger size is to go to your local jewellers. Here they will have a selection of ring sizes for you to try on to determine your size. It is also important to consider the ring you have in mind to purchase when getting your finger sized. A wide band ring will fit tighter than a slim band of the same size. Your jeweller should be able to size you with both. When purchasing a ring as a gift this may not be an option for you. In this instance what you can do is take a ring belonging to the recipient and get this measured at your local jewellers. However please note that this is not always accurate as the ring may not be worn on the same finger or may not even be a perfect fit. In any case getting an accurate ring size is essential especially when ordering diamond set rings, wedding bands and patterned bands as in some cases these rings can be expensive to resize or may not even be suitable for sizing. If you are not sure it always best to let us know and we can advise.
