How to measure your ring size
What you need:
- String, paper tape, or other non-stretchable material
- Pen or something that can be used to make marks
- Ruler or something that can measure in millimeters
- Cellophane tape (not required)
The size of a ring is determined by the inner diameter (circumference) of the ring.
Note:Wrap your paper tape around the thickest part of the finger (around the second joint) where the ring will be worn. Wrap it around just enough so that it is not too tight or too loose.
STEP1: Place cellophane tape on the paper.
STEP2: Put on a finger.
STEP3: Wrap the paper around your finger.
STEP4: Mark the overlapping area with a pen.
STEP5: Measure the length between the two marked points with a ruler. The number closest to the inner circumference in the ring size chart below is the ring size for that finger.
All MIYAMA rings are specified in standard US sizes. For finger circumference and ring sizes for other countries, please see the conversion chart.

*The best time to measure your finger size is at the end of the day.
*Take your ring size at your normal body temperature. Fingers change size slightly with temperature.
