So many different "standard" sizes. Paper is the worst. 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 basic size would have a mass of 24 pounds.
