(n) A tolerancing measure used to describe the theoretical size used as a starting point for the application of tolerances.

In inches, 25 x 38 for book papers, 23 x 35 for text papers, 20 x 2 for cover paper, 22 1/2 x 28, or 22 1/2 x 35 for Bristol, and 25 1/2 x 30 1/2 for Index

The customary sheet size used to establish the basis weight of a ream of a given grade of paper. Standard basic sizes vary by paper grade. For example, the basic size of watercolor paper is 22x30", while the basic size of cover stock is 20x26".

The size of paper used to define basis weight. Size varies depending on the paper grade. For example, the basic size of bond and writing papers is 17" x 22", whereas the basic size of offset papers is 25" x 38".

Standard sheet size per type of paper that determines the weight.

The size sheet determined by trade for figuring the basic weight on one ream. 17 x 22 for envelope paper.

(U.S.) The one size in each category of paper that is used to establish the weight of the sheet. Basic sizes differ from category to category. Bond and ledger papers have a basic size of 20 x 26 in.; book, offset, and text papers have a basic size of 25 x 38 in.

The theoretical or nominal standard size from which all variations are measured.

Term refers to a standard size of paper stock; even though the required size may be smaller or larger.

Specific, standard sheet size from which the basis weight of a given grade is determined.

The customary sheet size used to establish the bases weight of a ream (500 sheets) of a given grade of paper. Standard basic sizes vary by paper grade. ie: The basic size of book paper is 25" x 38", while the basic size of cover stock is 20" x 26".

The standard sheet size used to establish the basis weight of a ream (500 sheets) of a given paper grade. The basic size of text-weight papers, for instance, is 25" x 38", and the basic size of cover stock is 20" x 26".

The standard size of sheets of paper used to calculate basis weight in the United States and Canada.

The one standard size of each grade of paper used to calculate basis weight.

A standard, predetermined size for a particular type of paper.
