Definitions for **"Basis Weight"**

Weight (in pounds) of a ream of paper (500 sheets) in the basic size for that grade.

Weight (in lbs.) of 500 sheets of a certain "basis size". Usual "basis sizes" for our roll papers are: 25"x38" for offsets, opaque offsets, groundwoods, and catalogs 24"x36" for newsprints and directories 17"x22" for bonds From the above, we can deduce that 32 lb. newsprint (basis size 24x36) is the same actual weight as 35 lb. groundwood or offset (basis size 25x38). Also, 50 lb. offset (basis 25x38) equals 20 lb. bond (basis 17x22).

Weight of linerboard or corrugating medium expressed in terms of pounds per 1,000 square feet (MSF).

Weight of fabric per unit area, usually oz/yd2

The weight in pounds of a ream of paper cut to a given size. Most backing papers used in pressure sensitive laminations are based on a ream size of 24" x 36"/500's. Face papers are more typically 25" x 38"/500's.

The weight in pounds of one ream (500 sheets) of any given paper style.

Weight, measured in pounds, (500 sheets) of paper in its basis size. Purely speaking, substance weight is the term used to express the basis weight of bond paper (500 sheets of 17" x 22"); but basis weight and substance weight are often used interchangeably.

The Basis weight is the number of pounds that one ream of parent sheets weighs. Fifty-pound paper means one ream (500 sheets) weighs 50#. Reams come in different-sized sheets, though. Book-paper and text-paper sheets are 25" X 38". Bond paper is 17" X 22". Bristols are 22 1/2" X 28 1/2" or 35". Covers are 20" X 26". Comparative Basis Weights: Bond Text Cover Bristol 20 50-- 24 60-- 28 70-- 32 80-- 40 100 55 67- 120 65 80-- 80 100-- 100 120

Basis weight or base weight. Used to define printed papers. This is the weight of paper before impregnation, printing, and topcoating. The weight is specified in grams per square meter.

Weight per a selected unit of area of a grade of paper; grammage or "grams per square meter" is used throughout the world and scientifically in the United States; the U.S. uses many different weight designations, depending upon the type of paper, including fine paper.

See Substance Weight.

The designated fixed weight of 50 sheets of paper (one ream) in the paper's basic sheet size, used as the basis for measuring the substance of paper by weight. Different classes of paper, such as writing, cover, and book, have fixed basic sizes that determine the designated weights.

The weight in pounds of a ream of paper. Its metric counterpart is grammage, where mass per unit area is expressed in units of grams per square meter.

"Weight" of a given paper determined by the weight of 500 basic size sheets.

The weight of 500 sheets (one ream) of a standard basic size. For example, the standard basic size for bond papers is 17" x 22". A ream of basis 24 bond sheets in that size weighs 24 lbs. The basic size for text is 25" x 38", the basic size for cover is 20" x 26". Bond: Text: 20 lb. 50 lb. 24 lb. 60 lb. 28 lb. 70 lb. 32 lb. 80 lb.

weight of a ream of paper in standard-size sheets

In The United States, a paper's basis weight is determined by weighing 500 sheets of its basic size measured in pounds.

The weight in pounds of a ream (500 sheets of paper cut to a given standard size for a particular grade). Example: 500 sheets 25 x 38 of 80 lb. coated book paper weigh eighty pounds.

The weight in pounds of a ream (500 sheets) of paper in a given basis size. Thus, a 140 lb. watercolor paper will be one in which a ream of 22" x 30" sheets actually weighs 140 pounds.

Weight in pounds of 500 sheets (one ream) of paper cut to a given standard size.

Traditional paper basis weights common to each grade of paper are based on measurements determined hundreds of years ago by Arab papermakers. They represent the finished weight of a ream of paper in a size specific to the grade of paper. (These sizes are usually "parent sheet" sizes, not cut-size reams.) Therefore, weights are not always the same between grades. For example, a 20# writing/script paper is not less than half the weight of a 50# text paper but, rather, similar to it. A 24# writing paper is generally equivalent to a 60# text, while a 28# writing paper is generally equivalent to a 70# text paper. That's because the size of paper being weighed by the ream is different for text than for writing papers.

The weight in pounds of a ream (500 sheets) of paper cut to a given standard size for that grade; e.g., 500 sheets of 25 x 38 in. of 50 lb. book paper weighs fifty pounds.

The weight in pounds per ream of paper cut to its basic size in inches. A metric system is used outside of North America.

The weight in pounds of a ream (3000 sq. ft). eg 185lb/3000ft

The weight, in pounds, of a ream of paper cut to a standard basic size. Each major paper grade, like cover, bond, or watercolor, has its own basic sheet size which determines its basis weight. For example, the basic size of watercolor paper is 22x30" for 500 sheets; therefore 500 sheets of 140 lb. watercolor paper 22x30" will actually weigh 140 pounds. Although the sheets in a given ream of paper may be larger or smaller than this example, basis weight refers to how much that ream would weigh if all sheets were the related basic size.

In the United States, the basis weight is the weight in pounds of a ream (500 sheets) of paper determined by a basic size. However, the basis weight size varies by grade of paper. Throughout the world it is the grammage or grams per square meter.

Each major paper grade (such as cover, bond, or offset) has its own basic sheet size that determines its basic weight. For example, the basic size of book paper is 25" x 38" for 500 sheets. So, 500 sheets of 70 lb. offset book paper that is 25" x 38" actually weigh seventy poinds.

The weight of 500 sheets of paper cut to a standard specific size. A basic sheet size is common to each major paper grade. The basic sheet size of cut-sheet paper is 17" x 22". If the total weight of 500 sheets of 17" x 22" paper is 20 lbs., the paper is described as 20-lb. paper.

Weight per unit area of paper. Synonym: Grammage.

The weight, in pounds, of a ream of paper cut to a basic size. Each major paper grade, like cover, bond, or offset, has its own basic sheet size, which determines its basis weight. ie: The basic size of book paper is 25" x 38" for 500 sheets; therefore, 500 sheets of 70 lb. offset book paper in 25" x 38" will actually weight 70 pounds. Although the sheets in a given ream of paper may be larger or smaller than this example, basis weight refers to how much that ream would weigh if all the sheets were the related basic size.
