Definition: A2 paper dimensions
A2 paper is a standard paper size defined by the ISO 210 international paper size system, which is used widely around the world except in North America. A2 paper is a part of the A series, where each size is half the area of the next larger size (A1) and double the area of the next smaller size (A3).
Dimensions
A2 paper dimensions measure 42 × 59.4 cm or 420 × 594 mm, which equals 16.54 × 23.39 in. Compared to A3 paper dimensions, it’s double the size but half the size of A1 paper dimensions. As mentioned before, this is because the A series has a consistent aspect ratio of 1√2, which makes it easy to scale it up and down.
