Chinese Series



The RD0 paper size, a unique and less commonly known dimension, holds its own significance in the realm of standardized paper sizes. As part of the ISO 216 standard, it is meticulously designed to meet specific requirements and applications.

RD0 is not a member of the more familiar A, B or C series from ISO 216. Instead, it belongs to the RA and SRA series - an intriguing fact that sets it apart from its counterparts. The RA and SRA series are primarily used for commercial printing purposes because they provide extra space to accommodate bleed during printing processes.

When we delve into its dimensions, RD0 measures 860 x 1220 mm. This expansive size makes it ideal for large-scale print projects such as posters or architectural blueprints where detail and clarity are paramount.

Interestingly enough, despite being part of an international standard (ISO), RD0 does not have a direct equivalent in the ANSI (American National Standards Institute) system which is widely used in North America. This highlights how different regions have developed their own standards based on their specific needs and historical contexts.

While RD0 may not be as well-known as other paper sizes like A4 or Letter, it plays a crucial role in certain industries due to its unique dimensions and association with the RA/SRA series under ISO 216. It's another testament to how diverse and specialized our world can be - even when it comes down to something as seemingly simple as paper sizes.

Interesting facts about RD0

1. RD0 paper is a type of paper used for printing architectural and engineering drawings.

RD0 paper, also known as Drafting Paper or Reinforced Drafting Paper, is specifically designed for technical drawings in the fields of architecture and engineering. It has a smooth surface that allows for precise line work and is resistant to tearing.

2. The term "RD0" stands for "Reinforced Drafting Zero".

The "R" in RD0 represents the reinforcement added to the paper to enhance its durability, while "D" stands for drafting, indicating its purpose in technical drawing. The number "0" refers to the size of the paper.

3. RD0 belongs to the ANSI/ASME Y14 series of paper sizes.

The ANSI/ASME Y14 series includes various standard sizes of engineering drawing sheets used in North America. RD0 is one of these sizes, measuring 34 inches by 22 inches (864 mm by 559 mm).

4. RD0 paper follows a ratio of 1:√2.

The dimensions of RD0 paper follow the aspect ratio of 1:√2 (approximately 1:1.414). This ratio ensures that when you fold or cut the sheet in half along its longer side, you get two sheets with the same proportions as the original.

5. The history of global paper sizes can be traced back to Germany's DIN standardization in 1922.

In an effort to standardize paper sizes and facilitate international communication, Germany introduced DIN (Deutsches Institut für Normung) standards for various formats including A-series papers which are widely used today worldwide.

6. The A-series paper sizes are based on the geometric mean of 2:1.

The A-series paper sizes, such as A4 and A3, are designed with an aspect ratio of 1:√2. This means that when you fold or cut a sheet in half along its longer side, the resulting halves maintain the same proportions as the original.

7. The most commonly used paper size globally is A4.

A4 paper measures 210 mm by 297 mm (8.27 inches by 11.69 inches) and is widely used for printing documents, letters, and other everyday purposes in many countries around the world.

8. The B-series paper sizes are derived from the A-series sizes.

The B-series paper sizes, such as B5 and B3, are obtained by enlarging or reducing the corresponding A-series size while maintaining its aspect ratio. For example, B5 is slightly larger than A5 but retains the same proportions.

9. The C-series paper sizes are primarily used for envelopes.

The C-series includes envelope formats that match their corresponding A-series size. For instance, a C5 envelope can hold an unfolded A5 sheet perfectly without any need for folding or trimming.

10. Paper has been produced for over two thousand years using various materials like papyrus and parchment before wood pulp became popular in Europe during the Middle Ages.

Papermaking techniques have evolved throughout history with different civilizations using materials like papyrus in ancient Egypt and parchment made from animal skins during medieval times. Wood pulp-based papers gained popularity due to their abundance and ease of production during later centuries.
