The Atlas paper size measures 26 inches (660 mm) x 34 inches (864 mm), giving it a sizable total surface area of 884 square inches. Sometimes referred to as Double Elephant, this substantial sheet has traditionally been utilized for larger scale documents, artwork, posters and presentations demanding ample space. Its generous width and length suit applications like wide format charts, sizable business graphics, expansive architectural drawings, oversized educational displays, and commercial artwork needing ample area to incorporate considerable intricate details. Although the Atlas dimensions are not as vast as the super-outsized Antiquarian sheets, its origins similarly date back to when paper was handmade in individual custom sheets rather than machine manufactured, enabling each piece to be produced to unique oversized proportions as required. So the Atlas paper size has its roots in an age when papermakers could create made-to-order sheets tailored to particular large-format purposes like art, posters, and special presentations requiring as much extensive surface area as possible.
