The dimensions of A4 paper

A4 paper measures at 210mm x 297mm, making it the global standard for most printing and writing needs. As part of the ISO 216 system, its size is based on the √2 aspect ratio, allowing seamless resizing to other A-series formats like A3 and A5. This ensures A4 is perfectly suited for a wide range of applications, from formal business documents to creative projects.

A4 paper as the standard format and size

In Ireland, Europe and most of the world, A4 copier paper is the default size for offices, schools and homes. Whether it’s business contracts, school assignments, or personal letters, A4 printer paper ensures that documents maintain consistency in appearance and functionality regardless of where they are created or viewed.

Its universal adoption is due to its practicality and compatibility with printers, folders and binders. As part of the international ISO standard, it simplifies the exchange and formatting of documents across countries, making it a reliable choice in global communication.

Understanding the A series paper sizes

The A series is an internationally standardised set of paper sizes defined by ISO 216, characterised by a consistent aspect ratio of √2:1. It begins with A0, the largest size (841mm x 1189mm), and each subsequent size is half the area of the previous one. A4 (210mm x 297mm) is the most commonly used size for office documents, letters, and reports.

Other sizes in the series include A3 (297mm x 420mm), which is typically used for presentations and diagrams, and A5 (148mm x 210mm), ideal for booklets and notepads. Smaller sizes, such as A6, A7, and A8, are used for postcards, tickets, and business cards. The scaling of the A series ensures compatibility and ease of use across a wide range of industries globally.

The table below shows the dimensions of the A series paper sizes, listed in both millimetres and inches:

The difference between A4 and letter paper?

While A4 paper is the global standard, North America uses letter paper, which is slightly shorter and wider at 8.5 inches x 11 inches. This difference in size can cause formatting challenges when sharing documents internationally. In Europe, most printers and equipment are set up for A4, making it the more convenient and widely used option.

Everyday uses of A4 paper

A4 copier paper is a cornerstone of daily life in Ireland. It’s used for printing documents, taking notes, creating flyers, and completing school assignments. Its versatility also makes it popular for crafting, sketching, and other creative endeavours. Whether in an office, classroom, or home, A4 copier paper is a reliable and practical tool.

Everyday uses of A4 paper

The weight of A4 printer paper, measured in GSM (grams per square metre), determines its thickness and quality. Standard 80 GSM paper is commonly used for everyday tasks, while heavier options like 100 GSM offer a more premium feel. For specialised purposes, such as photo printing, thicker and smoother papers are available to improve the final output. However, some printers may not support thicker paper weights, so be sure to check your printer model in advance.

Printer compatibility with A4 paper

Printers in Europe are designed with A4 printer paper as the default size, ensuring ease of use for most tasks. Whether using inkjet, laser, or multifunction printers, A4 paper fits perfectly. Adjustments may be needed for other sizes, but A4 remains the most practical and widely supported option for printing at home or in the office.
