A-series printer paper

The A-series are the most widely used paper varieties internationally. In the United States, Canada, and the Philippines, paper sizes based on inches are used. The construction of the A-series is logical: it starts with A0. If you fold this sheet of paper in half along the long side, you get the next size in the series: A1. If you fold it in half again, you get A2. This continues until you have the smallest paper size in the A-series, which is A10. All of these sizes can be used as printer paper.
