Metric Paper Sizes

The basic size of metric paper is one square meter, which is the area of an A0 sheet of metric paper. This size, taken along with the aspect ratio, fully determines the size and shape of metric reprographics paper.

For a given sheet size, United States paper is a little wider than metric paper in the short dimension, and a little shorter than metric paper in the long dimension.

As can be seen, A0 size folded once is A1 size, folded twice is A2 size, folded thrice is A3 size, and folded 4 times is A4 size.

Metric paper also has a B series of sizes for posters and wallcharts and a C series of sizes for envelopes.
