Number of Stamps for A 5 x 7” Manila Envelope

This is the smallest size of the manila envelope. A small manila envelope is generally used for mailing invitations and letters. It also meets the USPS’s requirement to utilize as a First-Class mail service.

Depending on the manila envelope weight, you need to use accurate numbers of stamps. For example, if the envelope weighs less than an ounce, you need to use 1 domestic Forever stamp and expect to pay $0.63 for mailing.

As the weight of the manila envelope increases, so will the stamp number and mailing cost. If the envelope weighs more than 1 ounce, you will pay an additional $0.24 per ounce.

A 5 x 7″ manila envelope has a maximum weight of 3.5 ounces. Anything over this weight is considered a large envelope, and you’ll need to pay a similar value for a large envelope. Here’s a chart for precise understanding:

This is the medium size of a manila envelope, which has similar stamp requirements and value to the small-sized envelope. A 6 x 9″ manila envelope is categorized as a First-Class letter.

As with a small envelope, a 6 x 9″ manila envelope weighing less than 1 ounce requires 1 Forever stamp. Expect to pay $0.63 for sending the envelope.

The maximum weight limit for this manila envelope size is 3.5 ounces; additional ounces over 1oz will cost you an extra $0.24. You can follow the 5 x 7” manila envelope’s stamp number chart for a medium size manila envelope.

Number of Stamps for A 9 x 12” Manila Envelope

A 9 x 12″ manila envelope is the standard size, which is also categorized under large/flat mailing type. This manila envelope size is widely used for business purposes as an A4 paper (8.5 x 11″) can easily fit in it.

Therefore, the number of stamps and costs will differ from the above two manila envelope sizes. If you want to use a 9 x 12″ manila envelope, you need 2 domestic Forever stamps for an ounce. And an additional ounce stamp is required for each extra ounce.

You should expect to spend about $1.26 to mail a flat envelope. However, the charge for an additional ounce is $0.24, which is the same as the other two sizes. You can follow the below chart for a better understanding.
