Q: How do I measure a window envelope?
A: Regardless of their orientation, windows are always measured height x width. When measuring a window, the flap of the envelope should always be at the top. You then measure the distance the window is from the left and bottom of the envelope.

Q: Are your envelopes machine insertable?
A: Although not all of our envelopes are described as machine insertable, we carry a wide variety of machine insertable commercials, catalogs, booklets, and announcements. See all of our machine insertable products.

Q: Does it cost more to mail a square envelope?
A: Yes, it does. Square envelopes are unable to be processed through the USPS sorting machines. Therefore, the Post Office must handle these envelopes differently by manually entering the address into the system.
