The Kiku 4 paper format measures 227mm x 306mm (8.9 inches x 12 inches), resulting in a print area of 0.0694 square meters. Sometimes alternately referred to as "Chrysanthemum" or "Kiku" paper, this Kiku 4 variant maintains the same 1.35 aspect ratio signature to old Imperial Japanese Kiku-ban sheets used for fine artwork and calligraphy. With dimensions well-suited for needs requiring substantial printable space like graphical designs, high-fidelity images, and artistic presentations, contemporary Kiku 4 represents lingering traditional size influences still discovered amidst today's industrial Japanese printing landscape norms. As one of the most frequently encountered old-style formats along with standardized JIS sizes, the continued relevance of Kiku's dimensions pays homage to centuries of papermaking advancements during the Edo period - a lineage of quality and controlled formatting persisting within current regional standards.
