The height/width ratio of the A paper system is constant. The base format is a sheet of paper which measures 1 meter squared in area (A0 paper size). If you fold an A0 paper in two along the short size you'll have an A1-sized page. An A1 page folded the same way will result in an A2 size. Today the ISO standard has been adopted by every country except the United States and Canada.
North American sizes
-
In 1995 the American National Standards Institute created a set of paper sizes, which is used in the United States and Canada. The two most common sizes are "letter" (8.5 inches by 11 inches) and "legal" (8.5 inches by 14 inches).
