1. What is USPS Length Plus Girth?

The USPS (United States Postal Service) Length Plus Girth measurement is used to determine the dimensional weight and size restrictions for packages. It's calculated as the package length plus the distance around its thickest part.

2. How Does the Calculator Work?

The calculator uses the USPS formula:

Where:

• \( Length \) — Longest dimension of the package (in)
• \( Width \) — Second longest dimension (in)
• \( Height \) — Shortest dimension (in)

Explanation: This formula calculates the total measurement used by USPS to determine if a package meets size requirements and calculate appropriate postage.

3. Importance of Length Plus Girth Calculation

Details: Accurate length plus girth calculation is crucial for determining USPS shipping rates, ensuring packages meet size limitations, and avoiding additional surcharges for oversized packages.

4. Using the Calculator

Tips: Enter package dimensions in inches. Measure at the longest points for each dimension. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

A: For most USPS services, the maximum length plus girth is 108 inches. Packages exceeding this may require special handling or alternative carriers.

Q2: How do I measure package dimensions correctly?
A: Measure the longest side for length, the next longest for width, and the shortest for height. Always measure at the furthest points.

Q3: Does USPS use dimensional weight pricing?
A: Yes, USPS uses dimensional weight (DIM weight) for certain services, which considers both package size and actual weight.

Q4: Are there different rules for international shipments?
A: Yes, international shipments may have different size restrictions and requirements. Always check specific destination country regulations.

Q5: What if my package exceeds USPS size limits?
A: Oversized packages may require alternative shipping methods, special handling, or may be subject to additional fees.
