The cost for postage on the 9x11-inch envelope will vary depending on the weight. As of May 2014, the standard cost of a stamp is 49 cents in the United States.
I went to the post office today (1/07/11) and one manilla envelope (without the metal fastener) with one piece of paper in it cost $.88 - it weighed 1 ounce. The second envelope contained 8 pages and weighed 3 ounces and cost $1.22. So by my calculations the envelope alone weighed about an ounce and 8 sheets of 8.5x11" weighs 2 ounces. Hope that helps.

The cost to mail a 5 inch by 11 inch envelope depends on its weight and the mailing service used. As of October 2023, standard First-Class Mail rates for a letter up to 1 ounce start at approximately $0.66 in the U.S. For heavier envelopes or different mailing options, such as priority or international shipping, prices will vary accordingly.
