International Envelope Series



The E1 paper size, a member of the ISO 216 standard series, is a unique and versatile format. It measures 594 x 841 millimeters or approximately 23.4 x 33.1 inches. This makes it an ideal choice for large-scale presentations, architectural blueprints, or detailed maps.

As part of the ISO series, E1 adheres to the same aspect ratio as other sizes in this range - a square root of two (√2:1). This ensures that scaling between different sizes within the series maintains the content's proportions without distortion.

Interestingly, E1 is not commonly used in everyday printing but holds significant value in specialized fields such as engineering and architecture where precision and clarity are paramount. Its large dimensions allow for intricate details to be displayed clearly.

Furthermore, E1 is part of an extended range within the ISO series known as 'E'. The 'E' series is less common than its 'A' and 'B' counterparts but serves specific needs with its unique dimensions.

While E1 may not be your everyday paper size choice, it plays an essential role in industries requiring larger formats for detailed work. Its adherence to ISO standards ensures consistency and quality across all uses.

Interesting facts about E1

1: E1 Paper Size

E1 paper is a part of the ISO 216 standard series, which defines the sizes of paper used globally. It measures 841mm x 1189mm, making it one of the largest standardized paper sizes.

2: Origin of E1

The E series was introduced in Germany in the early 20th century by Dr. Walter Porstmann. The "E" stands for "Entwurf," which means "draft" in German.

3: Architectural Drawings

E1 paper is commonly used for architectural drawings, blueprints, and large-scale technical designs due to its spacious dimensions and ability to accommodate detailed plans.

4: Folding Possibilities

E1 paper can be folded into smaller sizes while maintaining its aspect ratio. For example, folding it in half results in two sheets of E2 size (594mm x 841mm).

5: Printing Challenges

Due to its large size, printing on E1 paper can be challenging for standard printers. Specialized wide-format printers or plotters are often required to handle this size effectively.

6: Limited Availability

E1 paper is not as widely available as smaller sizes like A3 or A2. It may require special ordering or sourcing from specialized printing suppliers.

7: International Usage

The ISO standard ensures that E1-sized documents can be easily exchanged between countries without compatibility issues, making it convenient for international collaborations and document sharing.

8: Poster Presentations

E1 paper is a popular choice for creating large posters for conferences, exhibitions, and presentations. Its size allows for impactful visual displays and easy readability from a distance.

9: Environmental Impact

Using E1 paper can have a significant environmental impact due to its larger size. It requires more resources to produce and generates more waste when discarded compared to smaller paper sizes.

10: Customization Options

E1 paper can be cut into smaller sizes or trimmed to fit specific requirements. This flexibility allows for customization based on project needs while still utilizing the standard E series dimensions.
