Architectural

Architectural paper, also known as Arch paper, is a specific type of large-format paper commonly used in architectural and engineering drawings. It is characterized by its dimensions of 24 inches by 36 inches (or sometimes 18 inches by 24 inches) and its ability to withstand the demands of technical drawing techniques such as drafting, sketching, and blueprinting.
