Definitions for "Paper Weight"
The weight in pounds, of 500 sheets of a particular grade of paper cut to a standard size.
The weight of paper is defined with the # symbol meaning "pound". The poundage of text paper in the United States is determined by the weight of 500 sheets measuring 25 x 38 inches. That measurement of area is called the "basis" size. Five hundred sheets of 50# offset text paper measuring 25 x 38 inches weigh 50 pounds. Five hundred sheets of 60# offset text paper measuring 25 x 38 inches weigh 60 pounds and so on. The weight of bond paper, used mostly in copy shops, is calculated using a different basis size 17 x 22 inches. Five hundred sheets of 20# bond measuring 17 x 22 weigh 20 pounds. Five hundred sheets of 24# bond measuring 17 x 22 weigh 24 pounds, and so on. If you do the math to compare the two different systems of weight measurement you will find that 20# bond is the same as 50# offset and 24# bond is the same as 60# offset. [Back
