Density Calculator

To determine the actual class of your freight it is best to utilize the National Motor Freight Classification guide. Class is partially based on density and Music Freight has created a Density Calculator to assist you. To find out your specific classification you should contact either your carrier or the NMFC guide.

In cases where the shipment is palletized, the dimensions of the pallet determine the cubic dimensions. Although the original dimension of the carton remains the same, the cubic dimensions now include those of the pallet.

Example: Length 48", Width 40", Height 28" (22" plus 6" of pallet) equals 53,760 cubic inches (Length X Width X Height) or 31.1 cubic feet (Length X Width X Height/1728). The density equals the weight 110 (80 lbs for the carton and approximately 30 lbs for the pallet) divided by the cubic dimension, 3.54 lbs per cubic feet. Once you determine the cubic feet you can look up the approximate class on the chart below.
