The Demy paper size measures 17.5 inches (445 mm) wide by 22.5 inches (572 mm) high, resulting in a sizable total surface area of 394 square inches. Sometimes referred to as Book, this common Imperial sheet has traditionally been used for moderate to large documents, manuals, folders, posters, artwork and publishing needs falling between standard and oversized formats. With its generous proportions and landscape orientation, Demy offers ample width for sizeable images, charts and tables while still compact enough for binding multipage documents. Its origins trace to an era when paper was made-to-order in custom dimensions, and Demy struck a useful balance between maneuverability and expansive area. For example, Demy made a very practical sized page for binding special presentation books, oversized record folders, sizable scientific sketches, quantitative business data books, and developmental artwork portfolios not quite needing a massive surface but still benefiting from the breathing room Demy provides over standard sizes. So Demy fills a niche as a spacious intermediate Imperial paper format.
