Belonging to the ISO 216 standard, the S11R paper size is a unique and versatile format. This international standard, recognized globally, ensures consistency in paper sizes across different regions and industries. The S11R size is part of this universal system, offering a specific dimension that caters to various printing and documentation needs.

The dimensions of an S11R paper are 648 x 864 millimeters or 25.5 x 34 inches. This makes it larger than the A series' A1 size but smaller than A0. Its unique size offers ample space for detailed designs or extensive text content, making it ideal for posters, architectural drawings, or large-scale presentations.

Interestingly enough, the aspect ratio of all ISO 216 paper sizes including S11R is √2:1 (approximately 1:1.414). This means that when a sheet is cut in half parallel to its shorter sides will result in two sheets with the same aspect ratio as the original one.

Moreover, unlike other common formats such as Letter or Legal from ANSI series used predominantly in North America, S11R's usage extends beyond regional boundaries due to its adherence to ISO standards.

Whether you're creating high-impact marketing materials or drafting intricate blueprints for your next project - consider leveraging the versatility of S11R paper size. Its unique dimensions combined with global recognition make it an excellent choice for diverse applications.

Interesting facts about S11R

1: S11R paper is a specific type of paper size.

S11R paper is part of the international standard ISO 216 series, which defines the sizes and dimensions of various paper formats. It falls under the A series, which is commonly used for printing and office purposes.

2: S11R paper measures approximately 620mm x 870mm.

The dimensions of S11R paper are standardized to be approximately 620mm x 870mm (24.4in x 34.3in). These measurements make it larger than most standard A-series papers, such as A4 or A3.

3: S11R paper is not widely used in everyday printing.

Unlike popular sizes like A4 or Letter, S11R paper is not commonly found in everyday printing applications. It has more specialized uses and may be utilized for specific projects or industries that require larger format prints.

4: The "S" in S11R stands for "Supplementary".

In the ISO 216 standard, the letter "S" denotes supplementary formats that are not part of the main series (A, B, or C). These supplementary sizes provide additional options for specific requirements beyond what the main series offers.

5: The aspect ratio of S11R paper is approximately √2 (1:√2).

The aspect ratio refers to the proportional relationship between a sheet's width and height. For all ISO papers, including S11R, this ratio remains constant at approximately √2 (square root of two), resulting in a consistent scaling factor when resizing between different formats within the same series.

6: S11R paper can be used for large-scale printing projects.

Due to its larger size, S11R paper is often employed for large-scale printing projects such as posters, banners, architectural plans, or engineering drawings. Its dimensions provide ample space for detailed designs and visual impact.

7: The ISO 216 standard was first introduced in the 20th century.

The ISO 216 series, which includes S11R paper, was first introduced in the early 20th century. It aimed to standardize paper sizes globally and simplify international communication and document exchange.

8: The ISO A-series is based on the German DIN format.

The ISO A-series of paper sizes, including S11R, is based on the German DIN (Deutsches Institut für Normung) format. The DIN standard was initially developed in Germany during the early 20th century and later adopted by the International Organization for Standardization (ISO).

9: S11R paper can be cut from larger parent sheets.

S11R-sized sheets can be obtained by cutting them from larger parent sheets of paper. This allows printers to customize their stock according to specific project requirements while minimizing waste.

10: Different countries may have alternative naming conventions for S11R paper.

While S11R is a recognized size within the ISO system, different countries may use alternative names or designations for this particular format. It's important to consider regional variations when discussing or sourcing this type of paper internationally.
