About Chinese K-sheet paper
Chinese full-sheet, 4K, 8K, 16K, 32K and 64K paper sizes, common in books and notebooks.
ISO A-series paper uses a 1:√2 aspect ratio: each size is half the area of the previous one, so A4 (210 × 297 mm) folds neatly down to A5 and enlarges to A3.
B-series paper is used for posters, books and envelopes; C-series envelopes are sized so an A4 sheet folds to fit a C5 envelope. Chinese K-sheet sizes (16K, 8K, 32K) remain common in books and notebooks.
