The Antiquarian paper size has dimensions of 31 inches (787 mm) x 53 inches (1346 mm), making it extremely large with a total surface area of 1643 square inches. Also referred to as Atlantic, Atlas, or Columbier Extra, Antiquarian has historically been used for exceptionally sizable documents, drawings, maps, artwork, and prints requiring vast sheets of paper. For example, Many old maps, nautical charts, and town plans were originally drawn on oversized Antiquarian sheets. Its substantial scale allowed cartographers and artists in past centuries to render considerable fine detail. While less common today due to standardized modern paper formats, Antiquarian's origins trace back to when paper was made by hand one sheet at a time with deckle edges rather than machine cut, meaning each sheet could be custom produced to any desired mammoth proportion. So the exceptionally sizable Antiquarian paper size stems from an era of crafting expansive customized sheets by hand for specialized purposes like intricate maps and artistic pieces.
