Filed under Paper Guide. The standard office copy paper weight is most commonly called â20 lb. bondâ. Standard office copy paper weighs approximately 10.0 lbs per 1000 sheets. When people talk about âoffice copy paperâ, theyâre referring to the types of paper that most people use for their printers and photocopiers at home/work.
There are three different scales that can be used to describe paper weight (also called paper density). The first is the U.S. system of Basis Weight, which is the weight in pounds of 500 sheets of paper in its basic sheet size. âBasic sheet sizeâ varies depending on the type, however, which makes it difficult to compare the weights of different types of paper. For instance, the basic sheet size of Bond paper is 17â³x22â³, while the basic sheet size of Tag Stock is 24â³x36â³.
