|How Many? A Dictionary of Units of Measurement
copyright Russ Rowlett and the University of North Carolina at Chapel Hill
In the U.S. paper industry, measurements of paper density and weight are based on traditional sheet sizes which vary with the type of paper. These standard sheet specifications have persisted, even though in many cases sheets of those sizes are no longer manufactured. Paper is described as, say, 24 pound weight if one ream (500 sheets) cut in the basis size would have a mass of 24 pounds.
The following basis size information is taken from Matt Roberts and Don Etherington, Bookbinding and the conservation of books: a dictionary of descriptive terminology. This reference, published by the U.S. government and not copyrighted, has been posted online by Stanford University.
