Architectural Standard Sizes

There is a corresponding series of paper sizes used for architectural purposes defined in the same standard, ANSI/ASME Y14.1, which is usually abbreviated “Arch”. This series also shares the property that bisecting each size produces two of the size below, with alternating aspect ratios. It may be preferred by North American architects because the aspect ratios (4:3 and 3:2) are ratios of small integers, unlike their ANSI (or ISO) counterparts. Furthermore, the aspect ratio 4:3 matches the traditional aspect ratio for computer displays.

The size Arch E1 has a different aspect ratio because it derives from adding 6 inches to each side of Arch D or subtracting the same amount from Arch E. An intermediate size between Arch C and D with a long side of 30 inches (760 mm) does not exist.

Unit of measurement

Unit of measurement is a definite magnitude of a value, defined and adopted by convention that is used as a standard for measurement of the same kind of value. Any other quantity of that kind can be expressed as a multiple of the unit of measurement.

mm (millimeter)
mm stands for millimeter (American spelling) or millimetre (SI spelling) is the size of the unit of length in the metric system, that is the basis of the length measurement. 1 mm is equal to 0.1 cm.

cm (centimeter)
cm stand for centimetre (international spelling as used by the International Bureau of Weights and Measures) or centimeter (American spelling) is a unit of length in the metric system, equal to one hundredth of a meter. cm being the International System of Units prefix for a factor of one per a hundred. cm is the base unit of length for cgs (centimetre–gram–second) system of units.

Inch (plural: inches, abbreviation: in or ″) is a unit of length in the imperial and United States customary systems of measurement, now formally equal to one per thirty six yard but usually understood as one per twelve of a foot. Derived from the Roman uncia, “inch” is also sometimes used to translate related units in other measurement systems. Traditional standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s it has been based on the metric system and reckoned as exactly 2.54 cm.
