1. placing a ring that fits you on a professional ring sizing mandrel.

2. placing your finger in a professional ring sizing tool

3. finding an approximate fit with a ring size chart for your finger

4. finding an approximate fit with a ring size chart for rings

Remember to measure your finger at room temperature as well as both the heat and cold can cause your fingers to swell or constrict. We have provided some useful information below including a free ring sizer and ring size chart that you may print and use and determine your correct ring size.

In order to print the ring sizer above, be sure that your printer is set to 100%. Make sure that you have not reduced the print size in your printer 'page setup' area. You can verify that the sizer printed correctly by measuring it with a ruler; it should measure from A to B: 3 1/2 inches long.

Once you have printed the sizer, follow these directions to find your ring size:

1. Cut out the ring sizer

2. Cut a slit for Slot "A"

3. With the numbers facing out, wrap the sizer around the finger where the ring will be worn.

4. Pull the pointed end Tab "B" through Slot "A" until the sizer is snug, making sure to allow size for the knuckle.

5. The number aligned with Slot "B" is your ring size.

6. If the measure lands between two numbers your size is a half size Ex: Between 5 and 6 ring size: 5.5. If half sizes are not available, order the next largest size.

NOTES:  Be certain to allow for the size of your knuckles, do not simply wrap the sizer around the ring place, attempt to pull it on and off.

All of these charts work the same with sizing a woman or a man.

The very best way to have your ring size determined is by a jeweler with a plastic or metal ring sizer that you try on.  Shimmerlings does carry this type of sizer and if you see J.Margherite at a show, she would be happy to help size your ring/finger.
