As we all know, paper comes in different sizes and dimensions. One of the most commonly used paper sizes is the A4 size. But what exactly is the A4 page in mm? In this article, we will delve into the details of this standard measurement for paper size, its history, and its use in today’s modern world.
History of A4 Page in mm
The concept of standard paper sizes began in Germany in the 1920s, with the introduction of the DIN (Deutsches Institut für Normung) system. This system was created to standardize paper sizes and make it easier for manufacturers to produce them. In 1975, the International Organization for Standardization (ISO) adopted the DIN system as the international standard for paper sizes.
The A series of paper sizes, starting with A0 as the largest and A10 as the smallest, were derived from the DIN system. The A4 size, which measures 210mm x 297mm, was established as the standard for business correspondence and documents. It quickly gained popularity due to its convenient size and became the most commonly used paper size in many countries, including the UK, Europe, and parts of Asia.
Understanding the A4 Size in mm
The A4 size measures 210mm x 297mm, or approximately 8.3 inches x 11.7 inches. It has an area of 623.70 square centimeters and is equivalent to half the size of an A3 paper, twice the size of an A5 paper, and four times the size of an A6 paper. The A4 size is also known as a “letter” size in the United States and Canada, where letter-sized paper measures 215.9mm x 279.4mm.
One important thing to note is that the A4 size is not a perfect square. The ratio of its sides is 1:√2, which means that if you fold an A4 paper in half widthwise, the resulting dimensions would be identical to those of an A5 paper.
The A4 size is widely used in various industries such as printing, publishing, and office supplies. It is also the standard size for many documents, including resumes, letters, and reports.
