The Arch Sizes or Arch paper sizes is usually used for “architectural” purposes such as the process and the product of planning, designing, and constructing buildings or any other “structures”. The current “standard” sizes are unique for some countries. The “unit” of measurements are in mm, cm, and inch.

The Arch Series Sizes Standard serially as follow Arch A, Arch B, Arch C, Arch D, Arch E, Arch E1, Arch 1, Arch 2, Arch 3, Arch 4, Arch 5, Arch 6. 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.
