How To Determine Your Ring Size


We realizes that you may not know the ring size for a given finger, and we hope the mentioned instructions are helpful.

Metal Ring Sizing Sets

If you don't know the accurate ring size of your finger, we highly recommend going to retail jewelry stores to measure your ring size with metal ring sizing sets.

 

If it is inconvenient to find a jewelry store nearby, and you can try the following method, which may have error limit.

Measuring Your Finger

Your ring should fit your finger comfortably, so that it will not fall off or slide over your knuckle.

To get best results measure your finger size:

  • 1. Measure it at the end of the day and when your fingers are warm (Fingers are smaller in the early morning and when cold.)
  • 2. Measure finger size 3 to 4 times to eliminate an erroneous reading.
  • 3. Avoid using string or paper to measure ring size as these materials can stretch or twist, yielding an inaccurate measurement

 

Measuring Your Current Ring

Inside Diameter

1. Select a ring that properly fits the intended finger.

2. Measure the inside edge of the ring to the circle nearest in size. This measurement refers to the inside diameter of the ring.

3. If the ring falls between two sizes, order the larger size.
