Girth Formula:
From: | To: |
Girth is a measurement used in shipping to describe the distance around the thickest part of a package. It's calculated by adding the width and height of a package and multiplying by two.
The calculator uses the girth formula:
Where:
Explanation: The girth measurement helps shipping companies determine pricing and whether a package can be processed through their automated systems.
Details: Many shipping carriers use girth plus length to determine dimensional weight and shipping costs. Packages exceeding certain girth limits may require special handling.
Tips: Measure the width and height of your package in inches at their widest points. Enter these values to calculate the girth.
Q1: How do I measure package dimensions correctly?
A: Measure at the longest point for each dimension. For irregular shapes, measure at the widest points.
Q2: Why is girth important for shipping?
A: Carriers use girth to determine if packages can fit through automated sorting equipment and to calculate dimensional weight.
Q3: What's the maximum girth for standard shipping?
A: This varies by carrier, but typically 60-108 inches is the limit before additional fees apply.
Q4: Does girth include the length?
A: No, girth is separate from length. Some carriers calculate "length plus girth" by adding the longest side to the girth measurement.
Q5: How accurate do my measurements need to be?
A: For shipping purposes, round up to the nearest inch. The calculator provides precise values for your reference.
