Basis weight is a paper weighting system. The basis weight of a paper is the designated fixed weight of 500 sheets, measured in pounds, in that paper’s basic sheet size. It is important to note that the “basic sheet size” is not the same for all types of paper. For example, Bond paper is typically 17″ x 22″, while Cover stock is typically 20″ x 26″.
The basis weight of a given type of paper varies depending on the kind of paper. For example, bond paper has a lower basis weight than cover stock. This is because bond paper is thinner and has a lower density than cover stock.
There are two different ways to express basis weight. The first is by using a number followed by the letter “b,” such as 50b. This designates the basis weight in pounds. The second way to express basis weight is by using a number followed by the word “points,” such as 50pt. This designates the basis weight in points. One point is equal to 1/1000th of a pound.
The basis weight of a paper is important because it affects the thickness and durability of the paper. Heavier basis weight papers are thicker and more durable than lighter basis weight papers.
Lighter basis weight papers are typically used for things like printer paper and photocopies, while heavier basis weight papers are used for things like business cards, postcards, and brochures.
Basis weight is an important factor to consider when choosing paper. It is a measure of the paper’s density and affects the feel, thickness, and finish of the paper. Heavier basis weights are generally thicker and more resistant to folding and tearing, while lighter basis weights are thinner and more likely to show ink through the paper.
