How to Size Yourself: Measure your fingers at the end of the day and not when they are overly cold of swollen from heat/ medication. The fingers on your dominant hand tend to be larger than those on your non-dominant hand, so make sure you measure each finger you want to purchase for. If the size of your finger below the knuckle drastically differs in size from the knuckle itself, measure your knuckle as well and choose a size that falls in the middle of the measurements.
