The Double Post paper size measures 19 inches (483 mm) wide by 30 inches (762 mm) high, resulting in a very sizable total surface area of 570 square inches. As its name denotes, Double Post offers twice the area provided by standard Post sheets. The considerable expanded size makes Double Post formats well-suited for more substantial documents, data tables, large visual aids, professional diagrams, artwork compositions and other applications benefited by ample added space to convey intricate details without getting into oversized specialty sheet ranges. Given its Post roots tied to postal correspondence history, Double Post lends itself efficiently to uses including sizable record books/folders, visual presentations, real estate/engineering plans, supersized business graphics, classroom display boards, commercial artwork pieces and general publishing precluded by confined standard Post proportions yet not requiring obscure huge dimensions. So for generous intermediate administrative and creative spreading purposes, Double Post handily fills a niche between limitations of conventional Post and extreme antique formats.
