Photographic Series
S30R
Belonging to the ISO 216 standard, the S30R paper size is a unique and often overlooked member of this globally recognized series. This specific format, while not as commonly used as its A-series counterparts, holds its own distinctive appeal and practicality.
The S30R dimensions are meticulously designed to adhere to the aspect ratio of √2:1, a characteristic shared across all ISO 216 paper sizes. This ingenious design ensures that when a sheet is divided into two, each resulting piece retains the original aspect ratio. It's an attribute that enhances consistency and versatility in various printing and design applications.

One might wonder about the 'S' in S30R. It stands for 'Supplementary', indicating that it's part of an extension to the primary A-series within ISO 216. The '30' denotes its dimension in inches along one side, while 'R' signifies its rectangular shape.
Interestingly enough, despite being part of an international standard series, S30R isn't widely adopted worldwide. Its usage is more prevalent in specific industries or regions where larger format sizes are required for specialized tasks such as technical drawings or architectural plans.
While it may not be your everyday paper size choice like A4 or Letter from ANSI series, S30R offers unique advantages with its consistent aspect ratio and larger dimensions. Its existence within the ISO 216 standard serves as a testament to the comprehensive nature of this international system - catering not just for common needs but also niche requirements.

Interesting facts about S30R
1: S30R paper is a specific type of photographic paper.
S30R paper is a type of resin-coated photographic paper commonly used in the printing industry. It is known for its high-quality image reproduction and durability.
2: S30R refers to the size of the paper.
The "S" in S30R stands for "Standard," indicating that it follows the standard sizing system for photographic papers. The number "30" represents the dimensions of the paper, which are 12 inches by 16 inches (or approximately 305 mm by 406 mm).
3: S30R belongs to the ISO A series of paper sizes.
The ISO A series is an international standard for paper sizes, widely used across the globe. S30R falls within this series and has specific dimensions that make it compatible with other ISO A sizes, such as A3 (297 mm x 420 mm) and A2 (420 mm x 594 mm).
4: The aspect ratio of S30R is approximately 3:4.
S30R has an aspect ratio of around 3:4, meaning that its width is three-fourths of its height. This aspect ratio allows for easy scaling and resizing without significant distortion or loss of quality.
5: S30R can be used for various printing applications.
S30R paper's versatility makes it suitable for a range of printing applications, including professional photography prints, posters, brochures, and art reproductions. Its resin-coated surface ensures vibrant colors and sharp details in printed images.
6: The history of global paper sizes dates back to ancient times.
The concept of standard paper sizes can be traced back to ancient Egypt, where papyrus scrolls were cut into standardized sheets. This idea evolved over time and became more formalized with the introduction of printing presses in the 15th century.
7: The ISO A series was first introduced in the 20th century.
The International Organization for Standardization (ISO) established the A series of paper sizes in 1975. It aimed to create a consistent and universally recognized system that would simplify printing and document handling across different countries.
8: The ISO A series is based on a mathematical formula.
The ISO A series follows a mathematical formula known as the square root of two (√2). This formula ensures that each size in the series maintains its aspect ratio when halved or doubled. For example, folding an A3 sheet in half results in two A4 sheets with identical proportions.
9: S30R paper is not commonly used outside of professional printing environments.
S30R paper is primarily utilized by professional printers, photographers, and graphic designers who require high-quality prints. It may not be readily available at regular stationery stores or used for everyday printing needs.
10: S30R paper offers excellent archival properties.
Due to its resin-coated surface, S30R paper provides enhanced resistance to fading, moisture, and aging. This makes it suitable for long-term preservation of important photographs or artworks without significant deterioration over time.
