Good Morning, I'm looking at the universal 9" double window envelopes in the 3 7/8" and 8 7/8" size. What I need to know is where the windows fall on the envelope. For example bottom window 1/2' from the bottom - top window 2". Window placement varys and I want to make sure I have the correct placement. Thank you. Karen

Thanks for your question about the Universal 9" Double Window Business Envelopes.


The windows on this envelope are 3/8" from the left.  The top window is 2" from the top of the envelope and the bottom window is 1/2" from the bottom of the envelope.  I hope this answered your question.
