This is a list of paper sizes in common use around the world.
||Most common paper size used
||Letter (8.5 × 11 in)
||Because Burgoignians aren't savages. Victors of the Standardized Stationary Melee of 1714, in which the Oligarchia grammaticorum adopted the 8.5x11 standard for its letters, the papermakers of the southern Dericania coast started the globalization of Letter sized paper. Their two-sheet mold technique was the most advanced Occidental papermaking method of the age. Their pulp drying frames spanned the maximum stretch of a papermakers arms, about 44". Many molds were 17" front to back. The resulting 44"x17" sheets were cut down to 8.5"x11" pieces to maximize the usage of the sheets.
||L4 (210 × 280 mm)
||The L4 paper size is designed for versatility as it combines the approximate length of standard letter paper with the width of A4. Using the smaller dimensions of each format allows the paper to be ostensibly used with equipment designed for either of the two most common measures in the world.
||E4 (219 × 310 mm)
||The origin of the E4 paper size in Diamavya is unknown. The few theorists that have discussed this topic haven't been able to find a reason why not only Diamavyan companies prefer producing this paper size, and why the Diamavyan populace continues to buy this paper size specifically. The only other paper size that is remotely used is A4 and Letter size, due to A4's prevalence in their Levantine Union and Letter size's use in Burgundie and Urcea. Both of these alternative paper sizes are not used by the populace, and are sometimes used by the government in foreign affairs, usually as a show of appreciation to the other country.
||Valēka Legal (9¾ × 15 in)
||Originated as a customary professional standard during the early 20800s among attorneys and legal printers in Valēka, and became widespread in the rest of the country in large part because so many mercantile contracts were printed on it. Its status as the national standard was cemented during Kirosocialism, as printers built by the state-owned Typographical Machine Works for general office use were designed to fit Valēka Legal size and the state-owned paper mills were directed to cut Valēka Legal in the largest quantities. A 21198 bill in the Federal Stanora to transition to an A4 standard was abandoned after impassioned street protests by paper and printing workers' unions, Coscivian nationalists, Kirosocialists, and National-Vigesimalists.
||Letter (8.5 × 11 in)
||A4 is also accepted from its usage in some Levantine Union countries. Urcea adopted the letter format following its widespread adoption by Levantine mercantile interests as detailed in the Burgundie entry above.
