# a series paper sizes The A series paper sizes are defined in ISO 216 by the following requirements:The length divided by the width is 1.4142The A0 size has an area of 1 square metre.Each subsequent size A (n) is defined as A (n-1) cut in half parallel to its shorter sides.The standard length and width of each size is rounded to the nearest millimetre.

• ### What is a series paper?

• ### What is the A0 size of paper?

• The base A0 size of paper is defined as having an area of 1 m2 and a dimension ratio of 1 to 鈭?. Successive paper sizes in the series A1, A2, A3, and so forth, are defined by halving the preceding paper size across the larger dimension.
