Ring Size Chart

Ring size is not the same as finger size. Also, on one finger alone a person may vary more than a whole ring size, depending on time of day, work performed, and other swelling-inducing activities/conditions. Other factors that can affect ring size include: the menstrual cycle, temperature, humidity, water retention, and exercise. Therefore, in most cases quarter-sizes are meaningless unless one needs precise accuracy with a particular ring. A professional jeweler can determine proper ring size using a set of steel gauge-rings. It has been recommended that fingers be measured at the end of the day, when they are at their largest diameters.

It is best for the consumer to know and be firm about finger dimensions, because every jeweler or ring seller will think his or her method is the "best" ring-measuring method. It has often been suggested that the industry universally standardize on using inner diameter (the diameter of the finger) as the only size-number method of determination. A wider band can be worn more loosely. Large knuckles/hands should wear a slightly loose ring, while slimmer knuckles/smaller hands will require a tighter ring. Some rings can be re-sized, but many cannot. Rings made of titanium or tungsten steel, stone-set rings with complicated or precise mountings, and extremely thin or wide rings cannot be re-sized.

A good way for a "rough-and-ready" measurement is to find a ring that is just smaller than the second knuckle of the finger. This way the fit is comfortable but will not slide off the finger. The method of trying on a ring and shaking the hand violently, to see if the ring comes off, is inadvisable and not very accurate.

How to determine your ring size

Wrap a piece of string or a strip of paper around your finger.
Mark the point where the two ends meet.
Measure the string or paper against a ruler to get the circumference of your finger.
Divide that by 3.14 to get the diameter of your finger.
Look up your ring size using the form above.
