How Many Stamps Do I Need Per Oz?

Although a great number of people communicate online using social media platforms, there are still plenty of reasons why you’ll need to use a stamp for the purpose of sending a letter through the United States Postal Service (USPS). One of the most common questions that often arises when preparing to send a letter is “how many stamps do I need per oz?” Whether you are sending a card to a loved one or mailing a letter for business purposes, the information below will ensure you know what’s required.

Cost of a Stamp

When sending a letter by mail today, the cost is $0.49. However, if you want to send someone a postcard, the cost is only $0.34. Some people buy a large number of stamps that go unused for years. Unfortunately, this can result in having stamps that are no longer the correct price for mailing a standard letter. This is exactly why the USPS decided to implement the Forever stamp back in 2007.

When the price of stamps change, a Forever stamp can still be used to send a letter without paying extra. This is the case even if you have had the stamps for years. Keep in mind that the letter must not weigh more than an ounce. When asked the question “how many stamps do I need per oz?,” the answer is one regular stamp.

Types of Letters That Require Additional Stamps

If mailing a letter within the United States, you can use a stamp at the current price or a Forever stamp. For each ounce thereafter, you will need to pay an additional $0.21. This is usually handled by placing one stamp onto the letter and going to the post office to pay the additional $0.21. It’s the best way to avoid wasting money.

If you have a letter that weighs more than 3.5 ounces, it will be classified as a large envelope. If you have an envelop that weighs more than 13 ounces, it will be considered a parcel instead of a letter. The amount that you need to pay is based on parcel rates. The cost to mail a parcel will depend on how much it weighs. The USPS makes it easy by providing a postage rate calculator.

Where Stamps Should Be Placed on Envelopes

When placing a stamp on an envelope, it should be positioned in the upper right corner. The proper location is on the same side where the address is located. If you are sending a letter that requires more than one stamp, you’ll need to make sure the stamps do not overlap.

Sending Mail to Another Country

If you are sending mail internationally to Mexico or Canada, you will need to pay $1.15 for a postcard or letter that does not weigh more than one ounce. If you have a letter that exceeds one ounce, the cost to mail it will depend on the country to which it’s being sent. There is a listing of fees for international postage provided by the USPS.

How Many Stamps Per Oz Depends on Classifications of Mail Service

Beyond First Class Mail, there are other classifications of mail that include Media Mail, Priority Mail Express, Priority Mail and USPS Retail Ground. All of these classifications of mail service have different rates.
