With the calculator on this page, you can calculate A paper sizes. In the calculator paper size, initially select an A series (4A1-A10). Then select the unit in which you want the calculation. In the last column, we show the result. Choose from the most common units. These are Micrometers (μm), Millimeters (mm), Centimeters (cm), Meters (m), Thou (th), Inches (in), Feet (ft), Yards (yd), Pixels, Pica, Point and HPGL.

### Calculate dimensions of the ISO 216 A series with the calculator paper size.

With the paper size calculator, you can easily calculate your A1 size. Make your choice below. The calculator calculates A-series from one unit to another. The A-series is not the standard everywhere. In the USA they use inches.

### Paper sizes in millimetres.

The dimensions of the calculator are the ISO 216 standards. The image below shows how the different A-paper sizes relate to each other. The A1 size is half the size of an A0 or two times an A2.

Size | Millimeter |
---|---|

4A0 | 1682 x 2378 |

2A0 | 1189 x 1682 |

A0 | 841 x 1189 |

A1 | 594 x 841 |

A2 | 420 x 594 |

A3 | 297 x 420 |

A4 | 210 x 297 |

A5 | 148 x 210 |

A6 | 105 x 148 |

A7 | 74 x 105 |

A8 | 52 x 74 |

A9 | 37 x 52 |

A10 | 26 x 37 |
