The number of Forever stamps needed for a 7 x 5 inch envelope depends on its weight. As of my last update, a standard Forever stamp covers the cost of sending a letter up to 1 ounce. If your 7 x 5 envelope weighs 1 ounce or less, you would need one Forever stamp. If it weighs more, additional stamps may be required based on the weight and current postal rates.
At that size and weight, it would cost $2.20 (as of 2016).
It depends on tne weight of the envelope not the size.
To mail a 2-ounce large envelope using Forever stamps, you would need to consider the current postage rate for that weight and size. As of my last update, a 2-ounce large envelope requires two Forever stamps, as each stamp covers the first ounce, and the additional ounce requires a second stamp. Always check the latest USPS rates for the most accurate information.
Postage is by weight - not size where letters are concerned.
Postage is determined by weight and by size. An envelope with three pieces of normal paper can normally be sent with one first class postage stamp. Additional stamps may be required based on additional ounces and on the size of the envelope.
That depends on what it weighs and where it's going ... not so much on its size. (It could also be related to the denomination of the stamps.)
To mail a 10x13 envelope from Frederick, MD to Baltimore, MD, you typically need one Forever stamp, as this size falls under the "large envelope" category for USPS. However, if the envelope exceeds one ounce, additional postage may be required. It's best to weigh the envelope to determine the exact postage needed. Always check with the USPS for the most accurate and current rates.
It is a combination of size and weight. The size will require an additional fee as it is classified as over-sized and doesn't get handled by machines. You will have to weight you envelope, which you can do at the post office.
The number of stamps needed for a large envelope depends on its weight and size, as well as the mailing service you choose. In the U.S., a large envelope (flat) that weighs up to 1 ounce typically requires one Forever stamp, but additional postage is needed for each additional ounce. It's best to check the current USPS rates or visit your local post office for specific requirements based on your envelope's weight and dimensions.
The answer will depend onwhich country you are posting from,where you are posting toin many countries, the size of the envelop.
If you buy the stamps and never use them, that's to many, if you buy stamps you think you might need and never use, that's to many, if you buy stamps just to have and admire them, that's collecting and your in the wrong section of WikiAnswers, you belong in collectibles.
One 49-cent stamp should be all that is needed.
