Measuring Ring Size

One of the tricky decisions while purchasing jewellery is deciding the ring size. It is especially difficult if you are ordering online as you cannot try it out yourself. So, let us help you with a simple chart that will enable you to be sure about your ring size.

The best way here is to use a ring that you already have and that fits you well. Then you can measure its dimensions and use the following chart. Here’s what you have to do,

·       Download and print this image in its original size.
·       Take the ring you own and put it on the circles in this picture and see which one is the closest match.
·       Please note that the inner edge of the ring should align with the outer edge of the circle. 
·       Also if your ring fits between the two circles, go for the larger size.
·       Also, print and cut the measuring strip.
·       Insert the narrow end of the sizer through the "cut here" slot.
·       Place the loop around your finger, with the numbers facing the outside, and then pull until the fit is snug but comfortable to find out your ring size.
