Your dominant hand’s ring size can be a half to a full size larger than the other, so choose the exact finger you want to wear your ring on.

Measure your finger when it is at its largest (usually end of the day) for the most comfortable fit.

Note that a thicker band will take up more space on your finger, so consider buying in a larger size.

Cold weather can cause your fingers to shrink a bit, while heat or water retention caused by food, medications, or illness can cause finger swelling.
