The open book behind the workbook refers to the size of a book width. It is the number of sheets of paper cut for the specification to indicate the size of the book. Cut a whole sheet of paper into 16 small pages of equal width, called 16 open, cut into 32 small pages called 32 open, and so on.
Because the standard of the whole sheet of paper has different standards, so, cut into small pages of different sizes. The 787 mm × 1092 mm paper cut into 16 small pages called small 16 open, or 16 open. The 850 mm × 1168 mm paper cut into 16 small pages called large 16. Other analogies.
