Belonging to the ISO A series, the medium paper size is a standard that's globally recognized and widely utilized. This particular size, often referred to as A4, measures 210 x 297 millimeters or 8.27 x 11.69 inches. It's an integral part of the ISO 216 standard, which is based on the German DIN 476 standard from 1922.

The medium paper size holds a unique position in this series due to its aspect ratio of √2:1. This distinctive ratio ensures that when a sheet is cut in half parallel to its shorter sides, it results in two sheets with the same aspect ratio as the original. This property makes it incredibly versatile for various applications ranging from professional documents to personal use.
