16K paper used in school personnel files is generally18.5× 26cm..

Later, due to the popularization and development of A4 paper, 16K paper gradually faded out of the market. The medical records used in hospitals are all about A4, but because it is necessary to print images for doctors to check and record in the medical records, if A4 ink-jet paper is used, the printed images will not be well preserved in A4 medical records. So the examination images printed by the hospital are all opened with 16.

16 paper mouth size is 185mm*260mm. Hospitals rarely use 16 to open paper, because the amount of paper needed by hospitals to write medical records is also quite large, and 16 is more expensive than B5, so hospitals now use B5 more.

In addition, the printing factory also has the standard of 16, but it is different from the size used in hospitals. The standard of 16 mentioned by the printing house is 185mmx260mm, which is widely used in the market.

16 folio is the concept of "folio" and "folio", which refers to the size of a book folio, that is, how many pages are cut on a fully open printing paper. There are thirty-two quarts (32K, mostly used for general books), sixteen quarts (16K, mostly used for magazines) and sixty-four quarts (64K, mostly used for small and medium-sized dictionaries and comics).

The concepts of folio and folio usually mean that a flat base paper cut according to national standards is a full open base paper. Under the premise of not wasting paper and facilitating printing and binding production, cut the fully opened paper into several small pieces with the same area, which is called how many sheets; Binding them into a book is called how many folio.
