Editing Paper size (section)

== Traditional British paper sizes ==
{{hatnote|The sizes used for historic "folio" books use a [[Folio#Size|different system]].}}
Traditional British sizes of cut paper, commonly used as stationery paper, are often referred to by the number of sheets that can be cut from a larger sheet of uncut paper.<ref name="old-imperial">{{cite web |title=British Imperial Paper Sizes |url=https://www.papersizes.org/old-imperial-sizes.htm |website=PaperSizes.org |access-date=8 August 2022}}</ref> The standard British imperial uncut paper sizes used in offices and schools were "foolscap", "post", and "copy". Each uncut sheet can then be halved into [[Folio|folios]], quartered into [[Quarto|quartos]], or eighthed into [[Octavo|octavos]].

A traditional British paper size in the British legal industry is brief (13{{pprime}} × 16{{pprime}}): this size was used by solicitors to write their briefs (court‑case instructions) for barristers.<ref name="Lister 1"/><ref name="Lister 2"/>

Uncut paper, on the other hand, is referred to by names only, not by the number of sheets that can be cut from a larger sheet of paper.
