    Custom Envelope Sizes

However, custom made envelopes require a minimum number of orders. This can range from a few hundred to over two thousand. The quality of the envelope will also be a factor.
    Measuring the Window

    To measure the window’s position on the envelope, begin from the envelope’s left side. For instance, start 1” off the left side. Step two is to measure from the bottom to the point where you want the window to commence.

    Now you can get the window envelope dimensions by measuring width x height. The same techniques can be used if the envelope has two windows.
