Does a single stamp cover my mail

In the United States, the answer depends on the weight and size of the mailpiece, as well as the distance it's being sent.

Here are some general guidelines:

1. Letters: A single Forever Stamp (currently $0.55) covers the cost of mailing a standard letter weighing up to 1 ounce and measuring up to 11.5 inches long, 6.125 inches wide, and 0.25 inches thick. If your letter is heavier or larger, you'll need additional postage.
2. Large Envelopes: For larger envelopes (also known as flats), the cost of postage depends on the weight and size. A single Forever Stamp might not be enough, and you may need to add additional postage.
3. Packages: For packages, the cost of postage depends on the weight, size, and distance being sent. You'll need to use a postage calculator or consult the USPS website to determine the correct postage.
4. International Mail: For international mail, the cost of postage is typically higher than for domestic mail. You'll need to use a postage calculator or consult the USPS website to determine the correct postage.

To ensure you have the correct postage, you can:

• Use a postage calculator on the USPS website
• Consult with a postal worker at a post office
• Use a postage app on your mobile device

Remember, it's always better to have a little extra postage than not enough, as you can always get a refund if you overpay.
