My document failed because it said it had too many pages...33
We currently offer #10 envelopes, which are the most commonly used business envelopes but can hold up to 7 sheets of paper (14 pages when printed on both sides (duplex)).
It is now possible to send up to 64 sheets of paper. When the letter contains 8-64 pages, the envelope used is changed automatically to a flat envelope (9in x 12in). There is no extra charge for the envelope however the USPS postage prices are different. See our pricing page for more details.
Please note: Currently, this option is available for black print letters sent from the United States only.
