A Series
A3+
Belonging to the ISO 216 standard, A3+ is a unique paper size that stands out in its series. This particular size, measuring 329mm x 483mm (or 13" x 19"), is slightly larger than the conventional A3 size of the ISO series. The additional space provided by A3+ offers an edge for professionals seeking to make a significant impact with their presentations or designs.
The A3+ paper size finds its roots in the international standardization organization's (ISO) efforts to create a universal system of paper sizes. It's part of the 'A' series, which is based on a logical and convenient aspect ratio of √2:1. This ratio ensures that when you cut or fold an A-series sheet in half along its larger dimension, it retains its original aspect ratio.

Interestingly, while most other sizes in the 'A' series are widely recognized and used globally, A3+ holds a special place primarily within industries such as professional printing and graphic design. Its extra dimensions provide ample room for bleed areas during printing processes - ensuring high-quality outputs without any compromise on design elements.
Despite not being part of ANSI standards commonly used in North America, A3+ has carved out its niche due to its practicality and versatility. Whether it's for creating impactful marketing materials or detailed architectural plans, this unique paper size continues to be favored by professionals who value precision and quality.
While it may not be as universally recognized as some other sizes within the ISO series, there's no denying that A3+ holds significant value within specific industries. Its unique dimensions combined with inherent benefits derived from ISO standards make it an intriguing choice for those seeking to elevate their printed materials.

Interesting facts about A3+
1: A3+ Paper Size
A3+ paper is a non-standard paper size that falls between the standard A3 and A2 sizes. It measures approximately 329mm x 483mm (13" x 19").
2: Origin of A3+ Size
The A3+ size was originally developed to accommodate printing needs for photographers and artists who required a larger format than the standard A3 size but did not need the full size of an A2 sheet.
3: Popular for Photo Printing
A3+ paper is commonly used for professional photo printing due to its larger size, which allows for more detailed and vibrant prints. It is often preferred by photographers who want to showcase their work in exhibitions or galleries.
4: Compatibility with Printers
A3+ paper can be used in printers that support larger formats, such as wide-format inkjet printers or certain laser printers. However, it may require manual feeding as it exceeds the standard tray sizes of most printers.
5: Versatility in Applications
Besides photography, A3+ paper finds applications in various other fields like graphic design, architectural drawings, engineering diagrams, and presentations where a larger canvas is needed to convey information effectively.
6: Limited Availability
A3+ paper may not be as widely available as standard sizes like A4 or even A3. It might require specialized stationery stores or online retailers that cater specifically to printing needs.
7: Customization Options
Sometimes referred to as "Super B" or "Tabloid Extra," the non-standard A3+ size allows for more creative freedom as it deviates from the traditional paper sizes. It offers artists and designers a unique canvas to work with.
8: International Variations
While A3+ is not an internationally recognized standard, similar paper sizes exist in different countries. For example, in Japan, B4 (250mm x 353mm) is commonly used, which is slightly smaller than A3+ but serves a similar purpose.
9: Paper Weight Considerations
When choosing A3+ paper, it's important to consider the weight or thickness of the paper. Heavier weights are often preferred for professional printing to ensure durability and enhance the overall quality of the print.
10: Environmental Impact
A3+ paper, like any other type of paper, has an environmental impact due to its production and disposal. Opting for recycled or sustainably sourced papers can help reduce this impact and promote eco-friendly printing practices.
