How do I know if I need 2 stamps?

Is One Stamp Enough? A Quick Guide to Postage Clarity

Sending mail can be a surprisingly confusing affair, especially when it comes to the seemingly simple question: How many stamps do I need? Slapping on a single Forever stamp might feel like the right thing to do, but incorrect postage can lead to your letter being returned, delayed, or even costing the recipient money. This article will help you navigate the world of stamps and ensure your mail arrives promptly and without incident.

The short answer: it depends! But don’t worry, figuring it out is easier than you think.

The Forever Stamp Standard:

For standard-sized letters, a single “Forever” stamp usually does the trick. This applies to your typical letter envelope, often referred to as a #10 envelope, that fits neatly into your mailbox. However, there are crucial caveats:

• Weight Matters: The single Forever stamp covers letters weighing up to 3.5 ounces. If you suspect your envelope contains a particularly weighty stack of documents, consider using a kitchen scale or visiting your local post office to have it weighed. A slight excess can easily push you over the limit.
• Rigidity Ruins the Rate: Even if your letter weighs under 3.5 ounces, its flexibility is important. Envelopes that are unusually rigid (perhaps containing a pen or other small item that doesn’t allow it to bend) require a higher postage rate. This is because they cannot be processed through the automated mail sorting machines efficiently.

When Two Stamps (or More!) Are Necessary:

Here’s where things get a little more complex. You’ll likely need more than one stamp in the following situations:

• Oversized Envelopes: This is the most common reason for needing extra postage. Larger envelopes, such as 9×12 envelopes, legal-sized envelopes, or manila envelopes (those used for mailing documents flat), are classified differently by the USPS. These are considered “large envelopes” or “flats.”
• Weight Beyond the Limit: If your standard or oversized envelope exceeds the 3.5-ounce weight limit for standard letters, or the 1-ounce limit for flats, you’ll need additional postage.

The “Large Envelope” Rule:

For these larger envelopes, the postage rules are different. Here’s the breakdown:

• First Ounce: A large envelope requires a significantly higher initial postage than a standard letter. Typically, two Forever stamps will cover the first ounce of weight.
• Each Additional Ounce: After that first ounce, you’ll need to add extra postage for every additional ounce or fraction thereof. As of this writing, this extra postage cost is typically around $0.27 per ounce.

Example:

Let’s say you’re mailing a 9×12 envelope containing a few sheets of paper. It weighs approximately 2 ounces. You’ll need two Forever stamps for the first ounce, plus $0.27 for the second ounce. You can either use three Forever stamps (overpaying slightly), or use two Forever stamps and one additional stamp valued at $0.27.

Best Practices and Avoiding Headaches:

• Weigh, Weigh, Weigh: Invest in a small kitchen scale or postal scale. It’s the easiest way to avoid guesswork and ensure accurate postage.
• Visit the Post Office: When in doubt, head to your local post office! Postal workers are experts in postage rates and can accurately weigh your envelope and advise you on the correct amount.
• Use Online Postage Calculators: The USPS website offers a postage calculator that can help you estimate the correct amount of postage based on the size, weight, and destination of your mail.
• Consider a Postage Meter: For businesses that send a large volume of mail, a postage meter can streamline the process and ensure accurate postage every time.

By understanding these simple guidelines, you can avoid the frustration of returned mail and ensure your letters arrive promptly. So, before you seal that envelope, take a moment to consider its size and weight, and you’ll be well on your way to postage perfection!
