Best Answer

The A4 paper size is defined as 210mm x 297mm because it is based on the international standard ISO 216, which uses a 1:√2 aspect ratio. This ratio ensures that when you fold the paper in half, the resulting dimensions maintain the same aspect ratio. This standardized size makes it easier to scale and reproduce documents consistently across different devices and countries.

What size is larger than A4 paper?

210 x 297mm those how are looking for the answer in cm you can not do it in cm ***unless you be scientific you will be able to work it out ** it will something like 21 x 29.35 ADDED: It won't be "something like", though your mm to cm conversion is not quite correct. 210 x 297mm = 21.0 x 29.7cm, and that will give an answer in square centimetres, not linear cm. In any case the question was asking for the area specifically, just the "size". When you buy the paper, or set up a printer to handle it, you don't really need to know the numbers because the A4 designation is the international standard and most printer-drivers, duplicators, fax machines etc have "A4" in their menus.
