To know how many stamps to use, consider the following:
- The number of stamps depends on the weight, size, and destination of your mail.
- For a standard letter (typically up to 1 ounce) within the US, one Forever Stamp usually suffices.
- If your letter weighs more than 1 ounce, you need additional postage for each extra ounce (for example, an extra 20 cents per ounce).
- Large envelopes or packages require more postage and stamps depending on their weight and size.
- For international mail, one Global Forever Stamp or several Forever Stamps are needed depending on weight.
- The current rate for a Domestic Forever Stamp is 58 cents, and additional ounces cost about 20 cents each.
The best way to determine the exact number of stamps is to weigh your mail, check the current postal rates or use the USPS online postage calculator. Stamps should be placed on the top-right corner of the envelope.
