Traditional British Series



Quarto, a term derived from the Latin 'quartus', signifies one-fourth. In the realm of paper sizes, Quarto refers to a sheet that is one-fourth the size of an original sheet. This unique dimension has its roots in traditional printmaking practices where a large sheet was folded twice to create four leaves or eight pages.

While Quarto isn't officially recognized in either ISO 216 or ANSI/ASME Y14.1, it holds significant historical and practical value. The dimensions of Quarto can vary based on the size of the original sheet, but traditionally, it measures approximately 279 x 216mm (11 x 8.5 inches), closely resembling an ANSI Letter or A4 from ISO series.
