Freight class and density calculator.

Determining the right freight class can save you both time and money. We’ve created an easy-to-use calculator to help you choose the right freight class and accurately plan your shipment.

Why do you need to know your freight’s density? Based on a shipment's dimensions and weight, density is one factor that influences freight classification. Typically, a shipment with lower density has a higher freight classification. See which class your freight falls into:
