Sheet, Half Post

The Half Post paper size measures 19.5 inches (495 mm) wide by 23.5 inches (597 mm) high, resulting in a reasonably sizable total surface area of 458 square inches. As its name indicates, Half Post provides roughly half the area of standard Post sized sheets. With its efficient landscape dimensions, Half Post strikes a versatile balance—fitting substantially more content than letter size yet without the bulk of full Post sheets. Its spacious proportions have lent themselves well to uses including large tables and charts benefiting from width in commercial settings, broad organizational graphics and flowcharts, sizable presentational visual aids, basic engineering diagrams, wall posters, and artistic compositions having moderate space requirements not quite demanding full Post proportions. Having origins tied to the legacy Post paper format which was ubiquitously used for postal correspondence history, Half Post sheets afford moderately generous spreading room well-suited for general business and technical documents warranting area surpassing conventional applications.
