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
Paperboard is a thick paper-based material. While there is no rigid differentiation between paper and paperboard, paperboard is generally thicker (usually over 0.30 mm, 0.012 in, or 12 Inch#equivalences, points) than paper and has certain ...

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.
Measurements
Most nations describe paper in terms of
grammage
Grammage and basis weight, in the pulp and paper industry, are the area density of a paper product, that is, its mass per unit of area. Two ways of expressing grammage are commonly used:
* Expressed in grams (g) per square meter (g/m2), regardle ...
—the weight in grams of one sheet of the paper measuring one square meter.
Other people, especially in the United States, describe paper in terms of
pound weight—the weight in pounds per ream (500 sheets) of the paper with a given area (based on historical production sizes before trimming): for card stock, this is ; as compared to newsprint (thinner paper) of . In describing paper, the pound is often symbolized by the pound symbol, ''#''. Because of the difference in the way pound weight is determined, a sheet of 65# card stock is thicker and heavier than a sheet of 80# newsprint.
The weight of cardstock ranges from 50# to 110# (about 135 to 300 g/m
2).
Rather than as a function of weight per sheet of a given area, paper thickness can be measured and stated directly, in units of linear measure. In the United States, this usually is expressed in
thousandths of an inch, often abbreviated ''
thou points'' (''pt.'' and ''pts.'') and ''mils''. For example, a 10 pt. card is thick (corresponding to a weight of about 250 g/m
2), and 12 pt. is . The thou point (1/1,000 inch) differs from the
typographical point (1/12 traditional

paper sizes
Paper size standards govern the size of sheets of paper used as writing paper, stationery, cards, and for some printed documents.
The ISO 216 standard, which includes the commonly used A4 size, is the international standard for paper size ...
, 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).

Paper density
Paper density is a paper product's mass per unit volume. The density can be calculated by dividing the grammage of paper (in grams per square metre or "gsm") by its caliper (usually in micrometres, occasionally in mils).
