Envelopes

All of us are familiar with envelopes. Envelopes are a basic everyday object used mostly in offices, to post letters, documents or cards. In this day of email and text, the art of writing letters as form of communication has taken a back seat in most people’s lives. But business is a different animal altogether. In business, envelopes are still considered an important office staple.

One of the most basic attributes of an envelope is the window. And as we all know because of the bills we receive through the mail, many envelopes have a window. Also, those letters with addresses of the correspondent printed on it, a windowed envelope may be the best solution, so that the address can show through.

But Size and Type are so confusing!

Although envelopes are a common occurrence, when we have to describe an envelope size, we get completely flummoxed and clueless! To the uninitiated, envelope sizes seem somewhat random. However, this is not the case. So to break down the envelope barrier we’ve listed the most common types of envelope styles and sizes that you’re likely to come across in an office environment.

So what are the standard envelope sizes?

Standard sizes for envelopes are C4, C5, C6, and DL. C4 is designed to accommodate A4 paper with ease. C5 is for the A5 paper. C6 for A6 and DL fits a an A5 sheet folded once.

Now we’re getting seriously technical!
Sizes of standard envelopes are as follows:

C4 - 324x229mm: size which is typically A4, meaning that you can place a full unfolded sheet in. These are predominantly used to carry documents that require the need to stay straight, such as brochures and tenders.

C5 - 229x162mm: These envelopes hold an A4 sheet of paper folded once or an A5 sheet unfolded.

C6 - 162x114mm: This type of envelope can hold an A5 piece of paper folded once, or an A4 piece of paper folded four times.

DL - 220x110mm: can hold an A5 sheet folded once. However, the most effective use is for an A4 piece of paper folded twice, as it fills both the height and the width of the envelope.

What about envelope seal?

And if we’re talking envelope seal, there seems to be just as many alternatives as there are envelope types and styles. Below are the most common options available:

Gummed: to seal the envelope, moisten adhesive flap and press to seal
Self Seal: simply fold the flap against the back of the envelope and press to seal
Peel and Seal: remove the strip to reveal an adhesive and press against the back of the envelope to seal
