The wider the band, the larger the size needs to be. Select one size larger than your actual ring size if the ring is wider than 4.0mm. 

Measure when hands are both hot and cold. You want the ring to fit no matter the temperature.

Does it twist? If it doesn’t the likelihood is it is too tight. A ring should be able to turn comfortably.

Finger sizes change during the day, make sure the ring fits at different points during the day.
