The Truth Behind Size Nomenclature

Have you ever wondered why envelope sizes are called A2, A4 or A5? Many people come to us and ask where that naming came from, why do we use the letter A and a number to describe preset envelope sizes. And it's a fair question because nowadays this is a widely accepted way of naming different industry sizes, but its origin and logic seem to be a mystery for anyone who isn't acquainted with the printing market. Even many industry veterans wouldn't be able to explain how this nomenclature works. So, here it goes.

This is no coincidence, there's a mathematical equation that reflects this ratio and was arguably invented in 1786 by German scientist Georg Christoph Lichtenberg who through a written letter to his colleague Johann Beckmann explained how he thought basing a paper size on an aspect ratio of √2 was a clear benefit to simplify paper sizes. This aspect ratio is the one that even today, more than 230 years later, still reigns in the paper industry.

Great offer.
I was a little surprised when I saw that there were paper options to chose from the blank envelops. I honestly thought they would be just normal white blank envelopes but it was a pleasant surprise.

My fiancé and I were looking for a reliable envelope supplier for our wedding invites. The variety on 4over4 is so large we almost couldn't pick out what we wanted but we eventually got to placing our order and it was promptly shipped and delivered and at a fraction of the cost of most other online stores. Thank you!!
