Get it right the first time
Fingers are slightly larger in the evening. Measure at the end of the day for the most accurate fit.
Cold weather shrinks fingers, heat swells them. Measure when your hands are at normal temperature.
Wide bands (over 6mm) fit tighter. If your ring has a wide band, consider sizing up half a size.
Your dominant hand is usually slightly larger. If ordering for your right hand, consider sizing up slightly.
