A page is one side of a leaf (a sheet or half-sheet) of paper, parchment or other material (or electronic media) in a book, magazine, newspaper, or other collection of sheets, on which text or illustrations can be printed, written or drawn, to create documents.
It can be used as a measure of communicating general quantity of information ("That topic covers twelve pages") or more specific quantity ("there are 535 words in a standard page in twelve point font type").
[1] The word "page" comes from the Latin term pagina, which means, "a written page, leaf, sheet",[2] which in turn comes from an earlier meaning "to create a row of vines that form a rectangle".
[3] The Latin word pagina derives from the verb pangere, which means to stake out boundaries when planting vineyards.
The number of pages is written in the same style (Arabic or Roman numerals, uppercase or lowercase, etc.)
