A Series



Belonging to the ISO 216 series, A0+ stands as a unique paper size that commands attention. This particular size, measuring an impressive 1189 x 841 mm, is the largest in the A series. It's designed to accommodate extensive information while maintaining clarity and readability.

The 'plus' in A0+ signifies its larger dimensions compared to the standard A0 size. This additional space provides room for bleed during printing processes, ensuring no crucial details are lost on the edges of your design or document.

Interestingly, the aspect ratio of all A series paper sizes is √2:1. This means when you fold an A0+ sheet in half along its shortest side, it will result in two sheets of the next size down (A1) without altering this aspect ratio.

A0+ is often utilized for large-scale applications such as architectural plans or advertising posters where detail and impact are paramount. Its expansive surface area allows for high-resolution imagery and comprehensive text layouts that can be viewed from a distance without compromising on detail.

In terms of ANSI standards, there isn't a direct equivalent to A0+. However, ARCH E (36 x 48 inches) comes closest but still falls short by comparison. This highlights how unique and versatile this ISO standard paper size truly is.

When considering your next big project or presentation, remember that choosing A0+ can make a significant difference in visual impact and information conveyance. It's not just about filling space; it's about maximizing potential with every square millimeter at your disposal.

Interesting facts about A0+

1. A0+ paper is not an internationally recognized paper size.

While A0 and A1 are part of the ISO 216 standard for paper sizes, A0+ is not officially recognized. It is considered an intermediate size between A0 and A1, measuring approximately 914 mm x 1292 mm (36 in x 51 in).

2. A0+ paper is commonly used for architectural and engineering drawings.

Due to its larger dimensions compared to standard sizes, A0+ paper provides ample space for detailed technical drawings, blueprints, and plans commonly used in the fields of architecture and engineering.

3. The aspect ratio of A0+ paper is the same as other ISO 216 sizes.

A unique characteristic of ISO 216 paper sizes is their consistent aspect ratio. The length-to-width ratio remains constant at approximately 1:√2 across all sizes, including A0+, ensuring easy scaling between different formats without altering proportions.

4. Some printers may offer custom cutting services for A0+ paper.

Since it falls outside the standardized range of ISO 216 sizes, finding pre-cut sheets of A0+ paper can be challenging. However, certain printing companies or specialized print shops may offer custom cutting services to meet specific requirements.

5. The origins of the "+" symbol in relation to paper sizes are unclear.

The exact reason behind using a "+" symbol to denote intermediate or non-standardized sizes like "A0+" remains uncertain. It likely emerged as a practical way to indicate variations from established standards without introducing confusion or disrupting existing naming conventions.

6. Despite its unofficial status, many professionals still use and recognize A0+ size.

Despite not being an internationally recognized size, A0+ paper continues to be widely used in various industries. Architects, engineers, and other professionals who require larger drawing areas often rely on A0+ sheets for their projects.

7. A0+ paper can be used for large-scale artwork and posters.

The generous dimensions of A0+ paper make it suitable for creating large-scale artwork or printing eye-catching posters. Its size allows artists to work with intricate details while ensuring the final piece has a significant visual impact.

8. The availability of A0+ paper may vary by region.

Due to its non-standardized nature, the availability of A0+ paper may differ depending on the country or region. It is advisable to check with local print shops or suppliers specializing in architectural and engineering materials for sourcing this specific size.

9. Some printers offer roll-fed options for A0+ printing.

To accommodate the larger dimensions of A0+ paper, certain printers are equipped with roll-fed mechanisms that allow continuous printing without the need for individual sheets. This feature is particularly useful when dealing with high-volume printing requirements.

10. The demand for A0+ paper has increased with advancements in digital printing technology.

The rise of digital printing technology has made it easier and more cost-effective to produce prints on larger formats like A0+. As a result, there has been an increase in demand for this intermediate-sized paper among professionals seeking high-quality output at larger scales.
