International Envelope Series
E2
Belonging to the ISO series, E2 paper size is a significant player in the realm of standardized paper dimensions. This particular size, measuring 660mm by 930mm, is part of the larger ISO 216 standard that governs A, B and C series worldwide.
The E2 paper size holds a unique position within this international standard. It's not as commonly used as its A-series counterparts like A4 or A3, but it still plays an essential role in specific applications. For instance, it's often utilized in architectural drawings and technical diagrams where larger format sizes are required.

One fascinating aspect of E2 and indeed all ISO paper sizes is their aspect ratio. The square root of two maintains consistency across all dimensions when scaling up or down. This means that if you fold an E2 sheet in half, you'll get two sheets of the next size down (E3), without any distortion or loss of proportion.
While ANSI standards are more prevalent in North America for traditional letter sizes, the ISO series including E2 remains dominant globally due to its logical and scalable system. Its universal acceptance makes it a reliable choice for businesses operating internationally.
While E2 may not be your everyday go-to paper size, its unique characteristics make it an indispensable part of the ISO family. Whether for large-scale technical drawings or international business use - when you need consistency and scalability - E2 delivers.

Interesting facts about E2
E2 Paper: Weird and Interesting Facts
1. Origin of E2: The E2 paper size is part of the ISO 216 international paper size standard, which was first introduced in Europe in the 19th century. It is derived from the A series sizes and is specifically designed for architectural drawings.
2. Unique Dimensions: E2 paper measures 445 mm × 635 mm (17.5 in × 25 in), making it larger than both A2 and B2 sizes but smaller than A1 and B1 sizes.
3. Architectural Applications: Due to its dimensions, E2 paper is commonly used by architects for creating detailed floor plans, elevations, and other technical drawings that require a larger working area.
4. Compatibility with Other Sizes: The E series papers are designed to maintain a consistent aspect ratio across all sizes within the series. This means that an E3 sheet can be divided into two equal-sized E4 sheets, just like how an A3 sheet can be divided into two A4 sheets.
5. Limited Availability: Compared to more common paper sizes like A4 or Letter, finding pre-cut E2 paper can be challenging as it is not widely stocked by most stationery stores or print shops.
6. Customization Options: If you require E2-sized prints but cannot find ready-made paper, many professional printers offer custom cutting services where they can trim down larger sheets to your desired dimensions.
7. Folding Possibilities: Given its larger size, folding an E2 sheet into smaller sections allows for convenient storage or transportation without compromising the integrity of the original drawing or design.
8. International Usage: While ISO standards are widely adopted globally, it's worth noting that the E series is not as commonly used outside of Europe, particularly in North America where architectural drawings are often created using different paper sizes.
9. Paper Weight Considerations: When selecting paper for E2 prints, it's important to consider the weight or thickness of the paper. Heavier weights are preferred for durability and to prevent ink bleed-through on detailed architectural drawings.
10. Digital Alternatives: With advancements in technology, many architects now prefer working digitally using computer-aided design (CAD) software instead of traditional pen and paper methods. However, E2-sized digital prints are still required for physical copies or client presentations.
