Which size is legal paper?

In most countries, A4 is the standard when it comes to print paper. The ISO 216 is the international standard for paper sizes. And when you talk about larger or smaller paper, you are talking about the other A-sizes. From A0 to A10. But these standard paper sizes do not apply worldwide. For example, in the United States, they use a different size A4 than we do in Europe. The most commonly used size in America is the US Letter.
