  • Use density to calculate freight class.

    Freightquote has developed a density calculator you can use as a guide to determine a shipment's freight class.

    Density is one factor used to calculate freight class. It's based on the shipment's dimensions and weight. A shipment with a lower density typically has a higher freight classification. Try our freight density calculator to see for yourself.
