The 9x12 open-end envelopes are one of the most economical envelopes available at this size. These are ideal for sending mass marketing mailers. These envelopes can accommodate a maximum insert size of 8.75 X 11.5 inches. The blank envelopes have a smooth finish.
A 9x12 window envelope holds standard 8-1/2 x 11 pages flat, so contracts, reports, statements and certificates arrive without folds. Position the address block on the first page so it lines up with the window, and the envelope is ready to mail.
USPS treats a 9x12 envelope as a large envelope, also called a flat. Large envelopes can be up to 12 x 15 inches and 3/4 inch thick, and they should be flexible and evenly filled so they run through postal equipment.
