What is the size of the Metric A4 paper?

The size of Metric A4 paper is 297 mm in width and 210 mm in height. This standard size is widely used for various documents, including reports, letters, and presentations. The A4 format is part of the ISO 216 standard, which defines paper sizes based on a metric system to ensure compatibility and uniformity across different regions.

The dimensions are derived from the A series, where each successive size is half the area of the previous one when the paper is cut in half parallel to its shorter side. A4 paper is commonly used in many countries around the world, making it an important standard in both commercial and personal printing.

In comparison, other sizes mentioned do not correspond to the A4 dimensions. For instance, the size of 420 X 297 mm represents A3 paper, while 594 X 420 mm corresponds to A2 paper, and 841 X 594 mm is indicative of A1 paper. Each of these sizes is larger than A4, illustrating how the A series progresses in size, reinforcing the specific dimension of A4 as 297 mm by 210 mm.
