Tips for Accurate Measurements

• Measure your finger at the end of the day when it is at its largest.

• Avoid measuring when your hands are cold, as fingers may be smaller.

• If your knuckle is larger than the base of your finger, measure both and choose a size between the two.

• If you fall between sizes, we generally recommend choosing the larger size for comfort.
