International Envelope Series



Belonging to the ISO 216 series, E6 paper size is a unique and often overlooked member of this international standard. This specific size, measuring 156 x 110 mm, is part of the lesser-known E series within the ISO standards. The E series is designed for envelopes and thus, E6 serves as an ideal choice for enclosing A6 documents without folding or creasing.

Interestingly, the dimensions of E6 are derived from a consistent aspect ratio of √2 (approximately 1:1.414), which is a distinctive characteristic shared by all sizes in the ISO 216 series. This aspect ratio ensures that two sheets of any size from this series placed side by side will result in the next size up in the series.

The practicality of E6 extends beyond just envelope creation. It's also utilized in various industries such as photography and printing due to its optimal dimensions that allow for minimal wastage during production processes.

Despite being less popular than its A-series counterparts like A4 or A3, E6 holds its own unique position within the ISO standards. Its precise dimensions make it an efficient choice for businesses seeking to reduce waste while maintaining professional presentation standards.

While it may not be as commonly recognized as other paper sizes, E6 plays a crucial role within its designated applications - proving that even in paper sizing, every dimension has its purpose and value.
