Standard Window Dimensions - Pitney Bowes DocuMatch Integrated Mail System Reference Manual

When using window envelopes, be sure they are made for
machine insertion. The patch has to be securely glued onto
the inside body of the envelope 1/8 in. over the edges of the
window opening. This helps the collated set to be inserted
cleanly without the edges of the material being caught by a
poorly glued window patch. An open-face envelope (no
patch) cannot be used on the DocuMatch system. A figure
of a standard window envelope is shown below.

Standard Window Dimensions

Here is the industry standard for window dimensions (Figure
