Envelope Sheet Capacity

We can fit up to 14 sheets of 8.5x11 20lb paper into a standard #10 outside envelope, or up to 75 sheets of paper into our large Flat sized envelopes.

On the "Create A New Job" screen, under the mail type section, the USPS Flat option will automatically place your documents inside a large flat envelope.  If you don't choose the flat option and then end up exceeding the 14 page limit our system will automatically convert your job to a flat mailing for you.
