How to determine your ring size

— How can I find out my ring size at home? Is there any reliable way?
— No, not really.

Explanation:
The only accurate way is to measure your finger using a special ring sizer at a jewelry store. Measuring with a string, caliper, or even comparing with another ring will most likely give the wrong result.

Factors that affect measurement accuracy:

— Time of day
Finger size changes during the day — usually smaller in the morning and larger in the evening. It’s best to measure in the evening.

— Finger shape
If you have prominent knuckles, a ring that fits well at the base of the finger might not go over the knuckle.

— Water and salt intake
Fingers can swell if you’ve had a lot of water or salty food, since salt makes the body retain fluid.

Ring sizers are available at almost any jewelry store or even small jewelry stands in shopping malls. In most cases, they will measure your size for free.
