The weight of cardstock generally ranges between 50 pounds to 110 pounds of bond weight, which refers to 500 sheets that measure 20 inches by 26 inches. This is in contrast to text weight, which refers to 500 sheets that measure 25 inches by 38 inches.
Cardstock may also be referred to as cover stock or pasteboard, and it is used for business cards and folders. Cardstock tends to have greater thickness and durability than standard writing or printing paper, which normally only has 20 pounds of bond weight. However, cardstock is usually thinner and more pliable than other kinds of paperboard.
