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.
Once you have the estimated density, use our freight class calculator chart below to find the recommended class for your shipment.
|Less than 1
|1 but less than 2
|2 but less than 4
|4 but less than 6
|6 but less than 8
|8 but less than 10
|10 but less than 12
|12 but less than 15
|Over 15 = class 70
