A0U
Belonging to the ISO 216 series, A0U is a unique paper size that holds its own in the realm of standardized dimensions. The ISO 216 series, renowned for its logical and practical approach to paper sizes, has been adopted by numerous countries worldwide, further amplifying the significance of A0U.
A0U stands out due to its distinctive dimensions. With a width of 841mm and a height of 1189mm, it's designed to accommodate large-scale prints such as architectural plans or detailed maps. This makes it an indispensable tool for professionals who require expansive space to convey intricate details.

One intriguing aspect about A0U is its aspect ratio. Like all sizes in the ISO 216 series, it maintains an aspect ratio of √2:1. This means when you fold an A0U sheet in half along its shortest side, you'll get two sheets of the next size down (A1), without altering the aspect ratio. This ingenious design ensures consistency and ease-of-use across various applications.
The 'U' in A0U signifies 'Untrimmed'. These sheets are slightly larger than their trimmed counterparts - a feature specifically designed for print production processes where bleed and trim are required.
A0U is more than just another paper size; it's a testament to thoughtful design and practicality that meets specific user needs while adhering to international standards.

Interesting facts about A0U
1. A0U paper is not a standard paper size
A0U paper is not recognized as a standard paper size in the ISO 216 international paper size system. It is an unofficial term used to refer to a custom-sized sheet that falls between A0 and A1 sizes.
2. A0U paper is commonly used for large-scale architectural drawings
Due to its larger dimensions, A0U paper is often preferred by architects and engineers for creating detailed plans, blueprints, and technical drawings that require ample space.
3. The dimensions of A0U paper can vary
Unlike standardized papers, the exact dimensions of A0U can vary depending on the specific requirements of the user or printing service. However, it typically measures around 841mm x 1189mm (33.11in x 46.81in).
4. It offers more creative freedom for designers
The larger surface area provided by A0U paper allows designers and artists to explore their creativity without limitations imposed by smaller sizes. It enables them to work on intricate details and experiment with various techniques.
5. Printing services may charge extra for A0U prints
Due to its non-standard nature and larger size, printing services may charge additional fees for printing on A0U paper compared to standard sizes like A1 or A2.
6. The origin of the "A" series dates back to Germany in the early 20th century
The international standardization of paper sizes began in Germany during the early 20th century when Dr Walter Porstmann proposed a series of formats based on mathematical principles known as the "DIN" system.
7. The A0 size is the largest in the A series
The A series of paper sizes follows a logarithmic scale, with each size being exactly half the area of the next larger one. A0 is the largest size in this series, measuring 841mm x 1189mm (33.11in x 46.81in).
8. The aspect ratio of A0U paper remains consistent with other ISO paper sizes
Despite not being an official ISO size, A0U paper maintains the same aspect ratio as other standard ISO sizes like A1, A2, and so on. This ensures compatibility and easy scaling between different sizes.
9. The "A" series has become widely adopted globally
The ISO 216 standard for paper sizes, including the "A" series, has been adopted by most countries worldwide except for a few exceptions such as Canada and the United States.
10. Paper thickness can affect print quality on large formats
When printing on large formats like A0U paper, it's important to consider the thickness or weight of the paper to ensure optimal print quality and prevent issues such as ink bleeding or wrinkling.
