Card stock
Paper, thicker and more durable than normal writing or printing paper

Card stock, also called cover stock and pasteboard, is paper that is thicker and more durable than normal writing and printing paper, but thinner and more flexible than other forms of paperboard.
01Use
Card stock is often used for business cards, postcards, folders, playing cards, scrapbooking, and other applications requiring more durability than regular paper gives. The surface usually is smooth; it may be textured, metallic, or glossy. Common surface finishes include wove (smooth), laid (parallel ribbing produced by a dandy roll), felt (a textured surface), and embossed patterns such as cordwain and linen. When card stock is labeled cover stock, it often has a glossy coating on one or both sides (C1S or C2S, for "coated: one side" or "coated: two sides"); this is used especially in business cards and book covers.

02Measurements
The weight of cardstock ranges from 50# to 110# (about 135 to 300 g/m2).
The length and width of card stock often are stated in terms of the ISO system of paper sizes, in which specific dimensions are implied by numbers prefixed with the letter A. Card stock labeled A3, for example, measures 420 × 297 mm (16.5 × 11.7 in).
