What are the dimensions of the Metric A2 paper size?

The dimensions of A2 paper size are 594 mm by 420 mm. A2 is part of the ISO 216 standard, which includes a range of sizes defined by their aspect ratio of √2:1. This means that each size is half of the next larger size when folded parallel to its shorter side.

When you take A1 paper, which measures 841 mm by 594 mm, halving it along the longer side gives you A2, resulting in dimensions of 594 mm by 420 mm. This relationship between sizes is fundamental to understanding the A series paper dimensions.

In this context, the given answer reflects the accurate relationship and size specified in the metric system, making it the correct choice. Other dimensions presented in the options represent either different sizes or miscalculations within the A series paper sizes.
