What are the standard paper sizes in Australia?

It goes without saying that the A series is the most common paper size class in Australia, with A4 being widely adopted as the standard document size for printing. The A series of paper covers a wide range of sizes, each of which have their own dimensions and unique applications.

Paper size dimensions

Getting to know paper size dimensions is crucial for anyone who works with paper, whether it's in an office environment or for personal use. Here are the A series dimensions and where these sheets of paper are commonly used:

A0

When it comes to paper sizes, A0 is the biggest of them all. Measuring in at 841 by 1189mm (or 33.1 by 46.8 inches), this mammoth sheet is typically used for large-scale printing projects. In fact, A0 paper size is commonly seen in technical drawing, where architects and engineers use it to create blueprints and house plans. It's also a popular choice for posters and promotional materials, allowing for bold imagery and sizeable text.

A1

A1 paper size is a commonly used paper size for advertising, display banners, and flip charts. This paper size measures at 594 x 841mm or 23.4 x 33.1 inches in dimensions. This size accommodates larger displays and presentations that require a significant amount of information to be presented at once. With A1, there is enough room to illustrate diagrams or graphs, while also providing ample white space for text and other materials.

A2

This particular size measures 420 by 594mm, or 16.5 by 23.4 inches. It's larger than your typical letter or legal paper, but not quite as big as a full-size poster. A2 dimensions make it a great option for all sorts of projects, from diagrams to calendars to medium-sized posters. In fact, you'll often see this size used for movie posters or in art galleries.

A3

Measuring at 297 by 420mm (11.7 by 16.5 inches), A3 paper is larger than the standard A4 size yet still manageable when it comes to handling and storage. This size is commonly used for design presentations, engineering plans, architectural drawings, and even restaurant menus. With its ample space, A3 allows for enough breathing room to accommodate detailed illustrations, tables, graphs, and other important visual aids.

A4

A4 is undoubtedly the most used paper size worldwide. Measuring 210 x 297mm, or 8.3 by 11.7 inches, this sheet type has become the standard for documents and forms around the world. Its size is particularly useful for printing long reports, making it a favourite among businesses that require extensive documentation in their operations.

A5

In millimetres, A5 measures 148 x 210mm, while in inches it equates to 5.8 x 8.3 inches. This versatile paper size can be found in everything from books and smaller magazines to leaflets and educational materials. A5 is a particularly popular choice for catalogues, booklets, and other types of informational materials that require a compact and concise format without sacrificing readability or visual appeal.

A6

Measuring at 105 x 148mm (4.1 x 5.8 inches), A6 is small enough to fit in your pocket yet large enough to showcase impactful designs and messages. A6 paper size is commonly used in various marketing collaterals such as postcards, flyers, small brochures, and even invitations. If you've ever received a save-the-date or an event reminder in the mail, chances are it was printed on A6 paper.
