‘A’ Series Paper

    Many paper size standards conventions have existed at different times and in different countries. The International Organization for Standardization(ISO) specifies international standard paper sizes used in most countries in the world today. For "A" series, have the same aspect ratio.(√2) This ratio has the unique property that when cut or folded in half widthways, the halves also have the same aspect ratio. Each ISO paper size is one half of the area of the next larger size in the same series. The challenge was how to inform the audience the system of ‘A’ series paper with using the actual size of ‘A’ series paper.
