2>>What’s the size of inner page?
Paper size refers to the size range of the paper that the folding machine collating machine can support, generally including a maximum size and a minimum size, which are generally expressed by paper specifications. If the paper is larger or smaller than this size range, the product cannot be folded and collated.

The format size prescribed by the country is a series of international standards adopted, and has been set into the national industry standard GB/T 1999 and implemented nationwide. The current format sizes of books and periodicals are mainly A series specifications, and there are the following types:
A4 (16k) 297mm×210mm
A5 (32k) 210mm×148mm
A6 (64k) 144mm×105mm
Among them, the size of A3 (8k) has not been fixed, but 420mm×297mm and A2 (2k) 420mm×594mm are commonly used.

Our products are displayed in standard A sizes and a range of the most common and popular sizes.
