When you think about printing on paper, it’s probably A4 size that comes to your mind. That is what most people use in their offices and homes after all. But have you heard about other dimensions and sizes? There is an international paper standard, that is associated with ISO 216 standard for paper sizes.
The ISO 216 standard is an international system used for defining paper sizes, and it is widely adopted in many countries around the world. According to this standard, the paper sheet must adhere to a certain dimensions in centimeters or inches.
You have probably seen printing paper blocks marked with A4 label, as these are the most common for regular usage. But have you ever worked with A3, A2 or A5 paper? Can you even tell which one of these is smaller or bigger than your standard A4? Keep on reading and you will learn much more about these paper sizes and how do they compare against each other.
As I already mentioned, the A4 is most widely used, probably because it’s so convenient and universal. The universality of this paper size comes in multiple ways: for example, you can fold and cut it in half to get two A5 sheets. And yes, this rule applies to all of the individual sizes within this standard, meaning that two A4 paper sheets adds up to one A3 sheet, where two A3 sheets makes one A2 and so forth.
I bet this makes paper sizing less confusing already, but you should stick around to learn more about these dimensions and how they add up. Comparing A3 to A4 will provide you with better insights into the relationship between different paper sizes and their practical applications. A3 and A4 are both part of the ISO 216 standard paper sizes. A3 is twice the size of A4, with dimensions of 297mm × 420mm. By halving the longer side of A3, we obtain A4, which measures 210mm × 297mm. This consistent ratio ensures that when you fold an A3 sheet in half, you get two A4 sheets of the same proportions.
The A3 size is often used for posters, architectural drawings, and presentations, where a larger format is required to showcase information or visuals. On the other hand, A4 is the most commonly used size for general office documents, letters, forms, and everyday printing tasks.
Understanding the relationship between A3 and A4 sizes can be helpful in various situations. For example, if you design a poster in A3 format but need handouts or smaller copies, you can easily scale it down to A4 size without losing the original proportions.
By delving deeper into these dimensions and their practical applications, you’ll gain a clearer understanding of the versatility and convenience that the ISO 216 standard brings to paper sizing. Here is a little cheat sheet that will help you to understand the relations and sequencing of ISO 216 standardized paper:

|A4||210 x 297 mm||21 x 29.7 cm||8.3 x 11.7 inches|
