Our Methodology
How the tools work
Start with shipment dimensions and weight, calculate freight density, and transfer shipment dimensions, weight, cubic feet, and density directly from the Freight Density Calculator into the Freight Class Calculator. You can also compare pallet layouts, estimate trailer space, and review commodity-specific freight guidance.
A typical planning path
1 · Measure
Capture the packaged dimensions and weight.
2 · Calculate
Calculate density and transfer the shipment values into the Freight Class Calculator.
3 · Estimate
Estimate freight class using shipment density.
4 · Review
Review packaging, handling, and commodity-specific considerations.
5 · Confirm
Confirm the freight class before requesting quotes or booking freight.
Available Freight Tools
Practical Freight Planning Tools
Each tool is designed for a specific stage of freight planning. Calculate shipment density, estimate freight class, compare pallet layouts, plan trailer space, and review commodity-specific freight guidance. When you use the Freight Density Calculator, you can transfer shipment dimensions, weight, cubic feet, and density directly into the Freight Class Calculator.
Freight Class CalculatorEnter the packaged dimensions and weight to get a density-based class estimate.
Freight Density CalculatorWork out cubic feet and pounds per cubic foot for one pallet or a mixed shipment, then transfer the values into the Freight Class Calculator.
Pallet Freight CalculatorCompare pallet size, quantity, stacking, weight, density, and estimated class in one place.
Freight Linear Feet CalculatorSee how many trailer rows a shipment uses and how much floor space it takes.
Freight Density ChartCheck the 13 density brackets and see where a shipment falls on the class scale.
Freight Class LookupBrowse commodity pages for packaging notes, shipment examples, and class guidance.
How the Tools Are Designed
Built around real freight workflows
Keeps weight and quantity together
Piece count, total weight, and stacking choices stay part of the calculation instead of being treated as afterthoughts.
Transfers shipment values between calculators
Transfer shipment dimensions, weight, cubic feet, and density directly from the Freight Density Calculator into the Freight Class Calculator. No need to enter the same shipment twice.
Offers options to test a different setup
Change dimensions, orientation, stacking, trailer width, or quantity and see how the shipment plan changes.
Shows how the result was calculated
The result pages include formulas, examples, and notes so you can check the inputs instead of trusting a random number.
Clearly explains calculation limitations
When packaging, commodity, carrier rules, or NMFC details may change the results the page will clearly mention it.
