1Index finger length: measure your index finger from the base crease (where it meets the palm) to the tip. Glove size is based on this length for a tactile fit.
2Palm width: gloves come in a narrow (N) or wide (W) palm for the same finger length. For easy on and off, choose the wider palm.
3Sense of touch: if you are within 2 mm of a size, a slightly shorter finger length gives a snugger, more tactile fit. This is a personal choice.
