Men's size 14, or 4XL, is the largest manufactured and stocked glove size available. Glove sizing is accomplished by measuring from the base of the hand to the tip of the middle finger. The total length is the glove size, meaning a size 14 glove is 14 inches long.
Glove making is a very old tailoring art. Internal glove sizes are specified by the size of the hand it needs to fit. External glove sizes, and the materials from which they are made, are dictated by their use. Glove types range from stylish form-fitting leather to rugged 2-foot-long Kevlar hockey goalie mitts.
