Do you have to **calculate paper size**? Here you will find a calculator that will allow you to know the measurements of the main papers (Series A, Series B and Series C) in different units (meters, cm, mm, inches and more).

You don't have to look any further **what is the size of an A4, A3, A5 or any other paper**. We provide you with the dimensions of the papers that are defined in the ISO 216 standard and the DIN 476 standard in which the standard paper dimensions are specified.

4A0 | 1682 x 2378 mm | 66.2 x 93.6 in. |

2A0 | 1189 x 1682 mm | 46.8 x 66.2 in. |

A0 | 841 x 1189 mm | 33.1 x 46.8 in. |

A1 | 594 x 841 mm | 23.4 x 33.1 in. |

A2 | 420 x 594 mm | 16.5 x 23.4 in. |

A3 | 297 x 420 mm | 11.7 x 16.5 in. |

A10 | 26 x 37 mm | 1.0 x 1.5 in. |

As you can see, **the largest paper in the A series is DIN A0.** which has an area of one square meter. As we reduce its surface by half (approximately), we obtain the rest of the paper types such as DIN A1, A2, A3, A4 and so on.

Please note that the above explanation involves a rounding of the figures and that DIN A0 actually has an area of 0.999949 m (0.999949 ft).^{2}
