The Large Post paper size measures 15.5 inches (394 mm) wide by 20 inches (508 mm) high, resulting in a generous total surface area of 310 square inches. As its name denotes, Large Post provides additional area compared to standard Post dimensions. The ample proportions of Large Post have made it suitable for more sizeable documents, tabular data, architectural sketches, expansion files, artwork compositions and other applications benefiting from spreading room beyond conventional business letter dimensions. With roots tracing back to general postal service use, Large Post offers a step up from standard Post's ability to fit reams of correspondence communication. Hence Large Post lends itself efficiently to uses including oversized recordkeeping folders, sizable business graphics, lengthy textual reports/proposals, visual presentation aids, commercial artwork needs, and similar documents precluded by confined standard sizes yet not requiring huge specialty format sheets. So for generous intermediate administrative and creative purposes, Large Post handily fills a niche between cramped conventional and unwieldy oversized extremes.
