What is the term used to describe the length and width dimension of paper?

The term used to describe the length and width dimensions of paper is "Paper Size." This designation is essential for understanding how a specific sheet of paper will be used in various applications, such as printing, framing, or crafting. Paper size typically includes measurements specified in units like inches or millimeters and follows standard formats like A4, Letter, and Legal, which are recognized internationally.

Options that discuss other aspects of paper do not directly reference the dimensions. For example, "Ream" refers to a quantity of paper, typically 500 sheets, usable for bulk purchasing and inventory management but doesn’t describe the actual dimensions. "Basis Weight" measures the weight of a standard ream of paper and indirectly relates to quality and thickness but not to the actual size. "Binding" describes the method of holding pages together, which has no connection to the paper dimensions. Understanding paper size is foundational in design and printing, as it influences layout, readability, and overall project planning.
