RING SIZE

When choosing a ring, it is important to know your (his/her) size accurately because when you have bought it, it becomes more difficult to exchange it or modify the size. 

In order to choose the right size for your ring, several factors have to be considered. First, when your hands are warmer (like in the summer, or when you have exercised), fingers will swell a bit so ring measurements will tend to be towards a higher size. When your hands are cold, on the other side, they will “shrink” and your size will appear to be smaller. Ideally, you should measure the finger where you will be wearing the promise ring during the afternoon or evening. The measurement should be made at the widest point of the finger (it might be at the knuckle, the ring needs to pass!). If you have other rings that fit well, you can also get their size by transferring their inner diameters into a sheet of paper. For both options, you will need a ring sizer. 

Measure your finger in warm temperatures at the end of the day

If your knuckle is larger than the base of your finger, measure both the base of your finger and your knuckle. Select a size between the two.

If you are buying the ring as a gift, ask your recipients mother or friend if they know his or her ring size or borrow one of your intended recipients and use the Ring Size Chart to the right to measure.

When considering a wide band, move up a size from your measurement for comfort.

You ring size will be about a half size larger on your primary hand (the hand you write with).

Using the Ring Sizing Chart, if you are between sizes, order the larger size.
