Freight Class Calculator

PWL has developed a freight class calculator you can use as a guide to determine a shipment’s volume and density.

Density is one factor used to calculate freight class. It’s based on the number of pieces in the shipment and the shipment’s dimensions and weight, ranging from 50 to 500. A shipment with a higher density typically has a lower freight classification.
