LTL freight calculators
Estimate your freight class from weight and dimensions, check density in pounds per cubic foot, and see how many linear feet of trailer your pallets will take.
How LTL pricing uses these numbers
Less-than-truckload (LTL) carriers price a shipment by its freight class, its weight and the distance it travels. Since July 19, 2025, most items without special handling needs are classed by density alone, so the two numbers you control are the weight and the measured size of each pallet.
Long or bulky shipments can also be priced by the trailer space they fill. Many carriers have a linear foot or cubic capacity rule in their rules tariff, and the threshold differs by carrier, so check your carrier's tariff when a shipment takes more than a few pallet rows.
Every class on this site is an estimate. The carrier may reweigh or remeasure, or apply an item-specific class, and that is the class you are billed at.
Common questions
What is the difference between freight class and freight density?
Density is a measurement: pounds per cubic foot. Freight class is the rating the carrier bills at, from 50 to 500. On the 2025 scale, density sets the class for most items, so 9 pounds per cubic foot is class 100.
Does a lower freight class cost less?
Yes. Class 50 is the cheapest per pound and class 500 the most expensive. Dense freight earns a lower class, which is why a smaller, heavier pallet can cost less per pound than a tall, light one.
