The Kiku 5 paper format has dimensions of 151mm x 227mm (5.9 inches x 8.9 inches), resulting in a print space area of 0.0343 square meters. Sometimes alternately referred to as “Chrysanthemum” or “Kiku” paper, this Kiku 5 size upholds the signature 1.5 aspect ratio of historic Imperial Japanese artistic sheets. Well-suited for graphical needs requiring substantial area like images, diagrams, and artwork presentations, contemporary Kiku 5 represents persistent traditional format influences still seen amidst today’s Japanese industrial printing landscape conventions. As one of the most commonly encountered old-style variants alongside standardized JIS sizes, the lingering relevance of Kiku dimensions pays respect to centuries of papermaking refinements since the Edo period - a legacy of quality and controlled precision carried on within modern regional standards.
