Kinds, Sizes, And Weights Of Paper

Common printing papers include bond, book, cover, bristol, newsprint, duplicator, and mimeograph. Each type serves distinct applications. Figure 5-6 details the typical uses, basic sizes, and basis weights for these papers.

The term basic size refers to the standard sheet dimensions in inches used by paper mills to calculate a paper's weight. This foundational measurement varies between different paper kinds. Mills typically offer paper cut to sizes other than this standard basic size.

Basis weight defines the weight in pounds of a ream (500 sheets) of paper cut to its basic size. Papers are commonly identified by this ream weight, such as 20-pound bond or 50-pound book. Most paper kinds are available in several basis weights to suit various project requirements.

Looking ahead to 2026, the printing industry continues to prioritize sustainable paper sourcing and production efficiency. Automation in digital printing workflows further refines the precision of paper handling and weight specification, ensuring consistent quality across both short and long runs.
