A Brief History of Envelopes

The history of envelopes dates back to ancient civilizations, where early forms of envelopes were used to enclose letters and important documents. In ancient China, envelopes were made of paper and used to store monetary gifts

The concept of folded paper envelopes, as we know them today, began to emerge in the 19th century. With the advancements in paper production and printing, envelopes became more standardized and widely used for personal and business correspondence.

The introduction of pre-gummed envelopes simplified the process of sealing envelopes, making them more convenient for everyday use. Over time, envelope designs and materials evolved, offering a wide range of options for different purposes and occasions.

In the modern era, envelopes continue to play a crucial role in communication, marketing, and stationery. With the advent of digital communication, envelopes have also adapted to new trends and technologies, remaining a staple in the world of paper-based correspondence and mailing.

Greeting card envelopes are an essential component of the card-giving experience, serving both functional and aesthetic purposes. Whether you opt for standard sizes or custom ones, the right envelope can elevate your greeting cards and make each recipient feel truly special. 


Greeting card envelopes come in various sizes, but the most common sizes are A2 (4.375" x 5.75") for smaller cards and A7 (5.25" x 7.25") for larger cards.

To make a simple greeting card envelope, you can start by measuring your card and adding 1/4 inch to each side. Then, cut a piece of paper to the calculated size, fold it according to the card's dimensions, and seal the edges to create the envelope.

An A6 envelope typically measures 4.75" x 6.5".

An A4 envelope usually measures 4.25" x 6.25". 

A 5x7 envelope typically measures 5.25" x 7.25".

Envelopes for standard-sized cards are usually slightly larger than the cards themselves to allow for easy insertion and removal. For example, a 5x7 card would typically be paired with a 5.25" x 7.25" envelope.
