A4 measurements in mm is a common topic that comes up when discussing paper sizes. A4 is the most commonly used paper size in many countries, including the United Kingdom and many European countries. It is also the standard for business and personal use in most parts of the world. In this article, we will delve into everything you need to know about A4 measurements in mm, from its origins to its dimensions and common uses.
Origin of A4 Measurements in mm
The A4 size was first introduced in 1975 by the International Organization for Standardization (ISO). It was based on the German DIN 476 standard, which specified the dimensions of paper sizes in millimeters. The A series of paper sizes, including A4, were created as part of the metrication process, aiming to standardize paper sizes across the world.
What is ISO?
ISO (International Organization for Standardization) is an independent, non-governmental international organization that develops and publishes standards for various industries. It aims to promote global standardization to facilitate trade and cooperation between countries. Its headquarters are located in Geneva, Switzerland, and it has members from 164 countries.
Why was the A series of paper sizes created?
Before the introduction of the A4 size, different countries had their own standards for paper sizes, resulting in confusion and difficulties when exchanging documents internationally. The A series of paper sizes aimed to address this issue by providing standardized dimensions that could be easily converted between different paper sizes.
Dimensions of A4 Measurements in mm
According to ISO 216, the dimensions of A4 paper are 210mm x 297mm or 8.27 inches x 11.69 inches. This makes it slightly longer and narrower than the American Letter size, which measures 8.5 inches x 11 inches. The A4 size has an aspect ratio of 1:√2, which means that when folded in half, it retains the same proportions.
How do A4 measurements compare to other paper sizes?
The A4 size is part of the A series of paper sizes, which ranges from A0 (largest) to A8 (smallest). Each size has a specific aspect ratio and is half the size of the previous one. For example, A3 is twice the size of A4, and A2 is four times the size of A4. This makes it easy to calculate the dimensions of different paper sizes within the A series.
What about the thickness of A4 paper?
The thickness of paper is often measured in grams per square meter (gsm). The standard weight for A4 paper is 80 gsm, but it can vary depending on the type of paper and its intended use. For example, printer paper is usually 80 gsm, while cardstock can range from 200-300 gsm.

A4 paper is used for a variety of purposes, including printing, writing, and photocopying. Its versatility makes it the go-to choice for many individuals and businesses. Here are some common uses of A4 paper:
