What do 8k and 16k of the calendar mean?

8k and 16k of the calendar refer to the size of the calendar. 8K is greater than 16K.

K= paper size. Full-open paper is 2-fold, 2-fold paper is 4-fold (a quarter of full-open), and so on.

For example: 16 paper opening =195 mmx271mm.

There are two kinds of paper: positive paper -787 x 1092. There is also large paper -850 x 1 168.

Take positive paper as an example:

Fully open =78 1x 1086,

2 on =530X760

4 on =390X540

8 on =27 1X390

16 On = 195x27 1

Note: Finished paper size = paper size-trimming size.

Many countries use the international standard ISO 2 16 to define paper size, which originated from Germany.

Adopted in 1922, three groups of paper sizes A, B and C are defined, including the well-known A4 paper size.

Group C paper size is mainly used for envelopes.
