Linear Feet Formula:
| From: | To: |
Linear feet calculation is used by FedEx and other carriers to determine dimensional weight pricing for packages. It combines the package's dimensions into a single linear measurement that represents the girth plus length.
The calculator uses the FedEx linear feet formula:
Where:
Explanation: This formula calculates the linear measurement by adding the length to twice the width and twice the height, which represents the package's girth plus length.
Details: Accurate linear feet calculation is crucial for determining shipping costs with carriers like FedEx. It helps ensure proper pricing based on package dimensions rather than just weight, especially for lightweight but bulky items.
Tips: Enter all dimensions in feet. Measure the length (longest side), width (middle dimension), and height (shortest dimension). All values must be valid positive numbers.
Q1: Why does FedEx use linear feet calculation?
A: FedEx uses linear feet to calculate dimensional weight pricing, which ensures that lightweight but bulky packages are priced appropriately for the space they occupy.
Q2: How do I measure package dimensions correctly?
A: Measure the longest side (length), the middle dimension (width), and the shortest dimension (height). Always measure to the nearest 0.1 ft for accuracy.
Q3: What is the maximum linear feet for FedEx packages?
A: FedEx has different size limitations depending on the service. Generally, the maximum linear feet (length + girth) is 130 inches for many services, but check specific service guidelines.
Q4: How does linear feet affect shipping costs?
A: Carriers charge based on either actual weight or dimensional weight (calculated from linear feet), whichever is greater. This ensures fair pricing for bulky items.
Q5: Can I use this calculator for other carriers?
A: While this formula is specific to FedEx's linear feet calculation, other carriers use similar dimensional weight calculations. Always check with your specific carrier for their exact formula.
