How do you determine the weight of an envelope?

To calculate the letter-size paper’s weight, you will need to divide 20 pounds by 2,000 sheets of paper, which gives you 0.01. You will then need to multiple 0.01 by 16, which is how many ounces there are in a pound. The result is 0.16 ounces per piece of letter-size paper.

A C4 envelope is designed to accommodate a full page of A4 paper. Great for small printed documents, certificates and magazines, this is a very common type of envelope.
