FedEx Linear Feet Calculation Formula
FedEx’s linear feet calculation follows specific mathematical formulas that consider multiple dimensions of your shipment. Understanding these formulas is essential for accurate cost projections and optimization.
Basic Linear Feet Formula
The fundamental formula for calculating linear feet is straightforward but requires precise measurements:
Linear Feet = Length (feet) + [Width (feet) / 12] + [Height (feet) / 12]
However, this simplified formula doesn’t account for the complex way FedEx actually applies linear feet pricing in practice. The carrier uses a more sophisticated calculation that considers how your freight would be arranged in a standard trailer.
FedEx’s Actual Calculation Method
FedEx uses a dimensional weight calculation that translates physical dimensions into a billing weight:
Dimensional Weight = (Length × Width × Height) / Density Factor
For FedEx Freight, the density factor is typically 10 (for pounds per cubic foot), but this can vary based on specific service types and freight classifications.
