International Envelope Series



The E10 paper size, a unique member of the ISO 216 standard series, stands out due to its distinctive dimensions. This particular size measures 44mm x 62mm, making it one of the smallest in the series. Its compact nature lends itself well to specific applications where space is at a premium.

ISO 216, which E10 is part of, is an international standard for paper sizes. It's widely recognized and used across the globe except in North America where the ANSI series holds sway. The ISO standard was based on the German DIN 476 standard from 1922 and has been adopted by most countries around the world.

Interestingly enough, all ISO paper sizes have a width-to-height ratio of square root of two (1:√2). This aspect ratio ensures that when you cut or fold a sheet in half along its longest side, you get two smaller sheets with exactly the same proportions as before.

E10's small size makes it ideal for printing labels or small notes. Despite its diminutive stature, this paper size can still pack quite a punch when used effectively. It's proof that sometimes less truly can be more.

E10 may not be as commonly known or utilized as A4 or Letter sizes but it certainly holds its own within the ISO family. Its unique dimensions and potential uses make it an intriguing option for those seeking to break away from traditional formats.
