Tips:
*Ideally, you should measure in the afternoon or evening when your fingers are at their most stable. To ensure accurate data, measure at least three times, as finger size can change throughout the day.
*Please also remember that the sizes of the right and left hands are different. Make sure to measure the finger on which you plan to wear your ring.
*A wider band means a tighter fit. If you're going bold, consider a bit of wiggle room.
*If your knuckle is larger than the base of your finger, measure both, then select a size between the two.
*If you hesitate between two sizes, always go with the larger one. If it is large, you can consider a ring size adjuster.
