Also called cover stock or pasteboard, card stock is thicker than copy paper or binder paper, yet surprisingly flexible, unlike cardboard. Card stock typically refers to paper with a weight range of 50# to 175# (#s equaling the weight of 500 20”x26” sheets), although its thickness may also be measured by thousandths of an inch in points or mils.
