The Quad Demy paper size has expansive dimensions of 35 inches (889 mm) wide by 45 inches (1143 mm) high, resulting in a remarkably large total surface area of 1575 square inches. As indicated in its name, the Quad Demy format provides four times the area of the standard Demy size. The exceptionally sizable Quad Demy sheets lend themselves suitability to specialized large format uses with surface area requirements going well beyond standard sizes. Applications that benefit from Quad Demy's enormous spread include oversized architectural site plans, super wide detailed multi-year timelines, extra-large advertisements spanning vehicle wraps for instance, massive multi-panel artwork, supersized technical or educational posters/displays, and contemporaneously bound extra-large historical folio documents among other specialized purposes. Despite its lesser ubiquity compared to common Imperial sizes, Quad Demy has filled a lucrative niche application where flat documents demand more generous proportions akin to widescreen cinematic formats. So for subject matter warranting sizes between standard sheets and historical antiquarian sheets, Quad Demy sheets afford copious surface real estate.
