How much postage is needed for a small package?

Determining Postage Costs for Small Packages

When sending small packages, it's essential to accurately determine the appropriate postage to avoid delays or additional charges. Postage costs primarily depend on package dimensions and shape.

Standard Envelopes

For rectangular envelopes that meet the following standard size criteria:

• Length: 3.5 to 6.125 inches
• Height: 5 to 9.5 inches
• Thickness: 0.25 inches or less

The postage starts at $0.73 for a 1-oz envelope. Additional ounces cost $0.24 each.

Non-Standard Envelopes

Envelopes that deviate from the standard size requirements, such as square, oversized, or oddly shaped envelopes, require a minimum postage of $1.19. This applies to envelopes with any of the following dimensions:

• Length exceeding 6.125 inches
• Height exceeding 9.5 inches
• Thickness exceeding 0.25 inches

Accurate Measurement

To ensure accurate pricing, it's crucial to measure the package dimensions precisely. Use a ruler or measuring tape to determine the length, height, and thickness in inches.

Additional Considerations

Note that these postage rates are based on domestic shipping within the United States. International shipping and other services, such as tracking or delivery confirmation, may incur additional costs. It's advisable to check with the postal service or use online postage calculators for exact rates and available options.
