When it comes to paper sizes, the A-series defined by the ISO 216 standard is among the most widely used globally. Among these, the A2 size holds a prominent position due to its versatility and range of applications. Whether you’re an artist, designer, printer, or simply someone dealing with large-format paper, understanding the specifics of A2 size is essential. In this article, we will dive deep into A2 size, its dimensions, uses, and how it compares to other paper sizes.
What is A2 Size?
The A2 paper size is part of the international standard paper sizes defined by ISO 216. This series is designed so that the aspect ratio of each paper size is the square root of two (approximately 1:1.4142). The beauty of this design lies in its scalability – when an A-size sheet is folded or halved, it retains the same aspect ratio.
Dimensions of A2 Size
In terms of measurements, A2 size is as follows:
- In millimeters: 420 mm x 594 mm
- In centimeters: 42.0 cm x 59.4 cm
- In inches: 16.5 inches x 23.4 inches
- In meters: 0.420 m x 0.594 m
- At 300 dpi (high resolution): 4960 x 7016 pixels
A2 is exactly half the size of an A1 sheet and twice the size of an A3 sheet. This hierarchy ensures seamless scaling for printing and design purposes.
Applications of A2 Size
A2 size is highly versatile and finds its use in various industries and applications. Here are some common uses:
