The Medium paper size measures 18.5 inches (470 mm) wide by 23 inches (584 mm) high, resulting in a sizable total surface area of 425.5 square inches. Living up to its direct name, Medium offers a middle-ground paper format fitting in between standard and oversized sheets. With its portrait orientation and ample area, Medium has traditionally lent itself well as a versatile paper size for general studio art needs, commercial drafting purposes, classroom display boards, basic engineering diagrams, standard business graphics, and various document publishing applications falling in between conventional and large formats. As an Imperial size dating back over a century, Medium's endurance across administrative, technical and creative sectors results from the utility of its middle proportion specifications - not so small as letter or legal to limit space, yet not so large as to prove cumbersome. So whether for mixed office use, commercial artwork, architectural drafting, or educational aids, Medium sheets hit the sweet spot right in the middle between cramped and expansive proportions.
