How to sellect the correct ring size?
Choosing the right ring size will take a bit of effort and time, but it is important. Too tight ring is uncomfortable or impossible to wear and too big ring will easily slip off from the finger. The size of the finger changes, even within the same day. In the morning and again in the evening the fingers are usually slightly swollen, as well as when the weather is hot. In the middle of the day on a cooler weather the fingers are smaller. Therefore the best setting for measuring your ring size is in the middle of the day in a normal room temperature.
Buying new rings is easy if you already know your ring size. Silk&Silver Jewelry ring sizes are equal to the inner diameter of the ring in millimeters. The other common ring size system is based on the inner circumference of the ring. The conversion table shows how these two different measuments correspond to each other.
Many jewelry stores have special measurement rings that can be used for measuring the correct ring size. At home the correct size can be tested by cutting a narrow shred from a flexible paper, curling it around the finger and using a pen to mark the spot where the paper ring feels comfortable. The length of the straightened shred will give you the circumference of the ring and the correct ring size can then be found from the conversion table.
It is important to keep the paper ring as round as possible for it to correspond the real ring. The type of the fingers defines the correct measurement point: a person with larger joints should take the measurement from around the joint, and a person with pointy fingers should take the measurement from the spot where the ring would normally go.
Also the width of the ring affects the size selection. Wide rings require approximately 5mm larger size.
If you want to have a ring in the same size as the one you already have, the easiest way to find out the size is to measure the inner diameter of the ring. The best tool for the job is a vernier caliper found at least in some homes. Also dividers can be used for transfering the ring diameter onto a ruler. Note that older rings may no longer be perfectly round and the measurement may be slightly incorrect.
