Depending on the size, weight, handling needs, and shipping risk of your LTL freight, your shipment needs the correct freight class so carriers can price it properly. Freight class is most relevant for US domestic and US cross-border LTL shipments between the USA and Canada.

Freight class is determined through the National Motor Freight Classification (NMFC) system. NMFC freight class is based on density, handling, stowability, and liability.

If you’re looking for a freight class calculator, density is a good place to start, but it is only one part of the full NMFC freight classification process.

  1. This density calculation is just one of the steps in determining correct NMFC class for your freight
    Density is one of the main factors used to determine freight class. This freight density calculator helps you calculate your shipment’s density in pounds per cubic foot.
  2. Measure your shipment carefully
    To get accurate LTL quotes, measure your shipment’s weight and exact dimensions in inches: length, width, and height. Round up to the nearest inch. For multiple pieces, measure each piece separately.
    Make sure your measurements include all packaging (pallets, boxes, crating, and other shipping materials).
  3. Get help confirming your freight class
    If you already know the correct NMFC code and freight class for your product, use that information when quoting and booking your shipment.
    If you’re unsure of your NMFC code or freight class, contact Freightera Client Care at (800) 886-4870 Ext. 1 or use our online chat. Our team can help you review your shipment details before you book.

How the freight density formula works

  1. It multiplies the length, width, and height of your shipment to get the total cubic inches.
  2. It divides the total cubic inches by 1,728 to calculate the total cubic feet.
  3. It divides the shipment weight by the total cubic feet to calculate density in pounds per cubic foot (pcf).
