When designing print files or checking finished product specifications, do you often feel confused by the different standards and complex "K" (kai) formats of the Japanese Kiku and Chinese 4/6 paper sizes commonly used in Taiwan? This tool uses a static data table to directly present the exact millimeter dimensions for various formats, from full sheet to 128K, under these two mainstream paper standard systems. "Paper size standards" refer to the width and height values in millimeters agreed upon by the printing industry to standardize production. This tool provides a complete reference chart for the Japanese Kiku (G format) and Chinese 4/6 (Specifications A and B) formats, helping you quickly get standard values without needing to memorize or manually convert them.
Q: What are the dimensions of Kiku 8K paper in millimeters?
A: The standard size for Kiku 8K (G8K) is 210 × 297 mm.
Q: Why does the Chinese 4/6 format have both Specification A and Specification B? How should I choose in practice?
A: Due to historical evolution and actual production practices in different regions, the 4/6 format developed two slightly different common standards. The dimensions for Specification A and Specification B vary; for example, 16K is 195 × 270 mm under Specification A, and 190 × 260 mm under Specification B. When choosing, you should prioritize the specific requirements provided by your printing house, publisher, or client. If there are no explicit requirements, you can refer to the more universally accepted specifications in the industry or check the physical dimensions of similar past products.
The dimensions provided by this tool are theoretical industry standard values. Actual printing and cutting may result in a ±1-2 mm margin of error due to equipment precision, paper characteristics (such as stretchability), and processing requirements. For important projects, we recommend final confirmation with your printer. Please note that the Kiku and 4/6 formats are two independent systems and should not be mixed. The tool's data is a static reference and does not cover other international standards like the ISO A/B series.
In Taiwan's printing practice, the Kiku format is often used for Japanese-style or specifically requested publications, while the 4/6 format is the mainstream choice for Chinese books, magazines, and notebooks. A key piece of advice is: before starting an important design, always confirm with your printing house which paper standard and specific format dimensions their equipment defaults to, especially regarding the A/B specifications of the 4/6 format. This can effectively prevent re-typesetting or material waste caused by file and paper mismatches. For example, when designing an A5-sized manual, the imposition method and finished size will be completely different if you use a Kiku full sheet (G1K, 636 × 939 mm) versus a 4/6 full sheet (1K, 787 × 1092 mm).
