How to Calculate USPS Stamps for a Standard Letter Size Manila Envelope

For many, determining the correct amount of USPS postage for sending a letter-sized manila envelope can be a challenging task. This guide helps clarify the process and provides a step-by-step approach to calculating the necessary postage.

Understanding USPS Mail Classification

Mail is categorized based on its weight, not its size. An envelope that looks large may not be charged the same as a smaller one depending on its weight and contents. It is crucial to determine the amount of written material within your envelope as well as the total weight of your package.

Common Envelope Sizes and USPS Rates

The most common envelope size used in the United States is the 10 size envelope, which measures 4 1/8 inches by 9 1/2 inches. This size is widely used for standard letters and documents. However, the cost to mail such an envelope depends on several factors.

For a standard 10 size envelope, if it contains 1 ounce or less of written material and is not stiff, it would start at 94 cents for Standard Mail. However, if the envelope is larger or contains more weight, the rate will increase.

The USPS website includes a very easy-to-use and highly accurate Postage Calculator. This tool allows you to input your specific details, such as the weight, size, and destination of your package, to determine the exact postage required. Here are the steps to use the calculator:
