The answer will depend on which country you are posting from and where to.
Yes, it is the same for the same weight. Both are considered 'oversized' mail or 'flats' and cost more than a normal business envelope. the current rate would be 88 cents for the first ounce and 17 cents for each additional ounce.
It means the weight of 500 sheets of the basis paper used to make the finished product. For instance, standard 8-1/2" X 11" paper is actually cut from a 17" X 22" basis, which produces 4 sheets when cut. So, 500 sheets of 17" X 22" paper that weighs 20 pounds would be 20 lb paper. Once it is cut and packaged for sale, 500 sheets no longer weighs 20 pounds, so the number becomes a guide for you to judge the relative thickness of different papers.
The circumference of the Earth (around the equator) is approximately 40,075.02 kilometers.The longest side of a paper, which is 11 inches, is 0.0002794 kilometers.Assuming the papers are placed so that the longest side follows the equator, and that each shortest side touches the two adjacent papers without any gap or overlapping, you can divide the equator's length by the length of a single paper to find:143432426.628489621, or 143,432,427 sheets of paper.
Using the 11 inch side for measurement purposes, you would need exactly 3.27 sheets, or rounding down 3 1/4 sheets.Using the 8.5 inch side for measurement purposes, you would need exactly 4.24 sheets, or rounding up 4 1/4 sheets.
1 square foot = (12 x 12) = 144 square inches100 square feet = (100 x 144) = 14,400 square inches8 x 11 = 88 square inches100 square feet = (14,400 / 88) = 163.63 = 164 sheets, with 32 square inches left over.
You will need postage for the weight of the envelope (probably 2 ounces, for 4 sheets of paper in a 10x13 envelope), plus a surcharge for the size of the envelope. Best guess: $1.19 for first class mail within the United States, as of Feb. 2014.
See page #12 of: http://www.southernct.edu/finadm/uploads/textWidget/wysiwyg/documents/USPS_New_Rates.pdf Not only does it let you know how many pages of mail you can mail for one stamp, it breaks it down by the type of envelope you use. As of 03/2009 it is 1-5 sheets of 20 pound copy paper in a #10 envelope or 1 ounce 1-4 sheets of 20 pound copy paper in a 6x9 envelope or 1 ounce Total envelope must be less than 1/4 inch thick. If you don't want to buy exact postage you can us 2 stamps for up to 3 ounces with the envelope less than 1/4 inch thick. In a #10 envelope that is 17 sheets of 20 pound copy paper In a 6x9 envelope that is 16 sheets of 20 pound copy paper Keep in mind the number of sheets is approximate and paper weight will make a difference!
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.
One fourth of an A4 sheet would fit in a C6 envelope. Or rather an A4 sheet folded in 1/2 then in 1/2 again. An A4 is a European size paper similar to our 8 1/2 x 11 inch sheets.
11 1/2 inches by 6 1/8 inches
