Dukes (140 × 178mm | 5.5 × 7in) from Traditional British Paper Sizes

Before the advent of ISO 216, England, the British Isles and the British Commonwealth countries used a variety of paper sizes, many of which have unusual names such as Double Crown, Elephant, Double Elephant, Demy, Double Pott and Columbier. Although they are now almost forgotten these paper sizes may still be obtained from specialist paper manufacturers.
