Density Calculator
Use this LTL density calculator to measure your shipment’s freight density based on its dimensions and weight. Enter your shipment details below to calculate freight density and get an estimated applicable freight class before your shipment is picked up.
FREIGHT DENSITY CALCULATOR
Enter your shipment’s quantity, dimensions, and weight to calculate cube density and estimate freight class.
Note: If palletized, include the pallet height in the total.

Why Freight Density Matters for LTL Shipping
Accurate freight density is a major factor in how LTL shipments are classified and priced. Carriers use density to understand how much space a shipment occupies relative to its weight, which directly affects the freight class assigned to it.
When freight density is incorrect, carriers may re-weigh or re-class the shipment after pickup. These adjustments can add an average of $50-$150 per shipment and lead to billing disputes or delays.
- It determines your shipment’s freight class
- It influences how LTL carriers price space and handling, including accessorial charges
- Incorrect density increases the risk of re-classification after pickup
How to Calculate Freight Density
Freight density is calculated using this formula:
Freight Density (lbs/cu ft) = Total Weight (lbs) ÷ Total Cubic Feet
3 Steps to Calculate Freight Density
Measure Your Shipment’s Dimensions
Convert Cubic Inches to Cubic Feet
Calculate Density- Volume: (48 × 40 × 48) ÷ 1,728 = 53.33 cubic feet
- Density: 500 lbs ÷ 53.33 cu ft = 9.38 lbs/cu ft
- Freight Class: 125-150
Freight Density to Freight Class Reference
While NMFC (National Motor Freight Classification) guidelines can vary by carrier, freight density generally maps to freight class as follows. Using accurate dimensions and total density helps ensure appropriate classification and fewer disputes with LTL carriers.
| Density (lbs/cu ft) | Typical Freight Class | Example Commodities |
|---|---|---|
| 50+ | Class 50-55 | Full pallets of canned or bottled beer, dense cases of canned beverages, tightly packed energy drinks, full kegs shipped with minimal dunnage |
| 35-50 | Class 60-65 | Bottled water, shrink-wrapped beverage cases, full-product beer pallets (glass or cans), fruit purée for brewing |
| 22.5-35 | Class 70-85 | Craft beer in mixed packaging formats, bottled kombucha, wine cases with protective inserts, compressed hops pellets |
| 15-22.5 | Class 92.5-110 | Mixed beverage pallets, empty kegs (1/6 BBL or 1/4 BBL) stacked per pallet guidelines, prepared foods with insulated packaging |
| 10-15 | Class 125-150 | Specialty beverages, light packaged food products, loosely packed empty kegs, shipments with added dunnage or insulation |
| <10 | Class 175-400 | Promotional beverage displays, empty kegs shipped loose, empty glass bottles or carboys, lightweight or non-stackable packaged goods |
Disclaimer: Always confirm accurate classification of freight class with your carrier or logistics provider.
FREQUENTLY ASKED QUESTIONS
Freight density refers to how much weight is packed into a given amount of space, measured in pounds per cubic foot (PCF). Carriers use freight density to determine a shipment’s right freight class, which directly impacts LTL shipping rates.
Higher-density freight typically takes up less space, stacks more easily, and ships at a lower freight class. Lower-density freight uses more trailer space and usually ships at a higher class.
- Measuring pallets without accounting for overhang
- Forgetting to include pallet or packaging weight
- Estimating freight class instead of accurately calculating density
- Using inconsistent units (inches vs. feet)
Yes. Freight density and freight class are primarily used for LTL (less-than-truckload) shipments. For full truckload shipping, pricing is typically based on trailer space rather than freight class.
Yes. This tool works as a pallet density calculator for single or multiple pallets by calculating total cubic feet and total weight.
A “good” freight density is typically 35 lbs per cubic foot or higher, which often corresponds to lower classes and more favorable LTL rates.
Re-classification often occurs when actual freight density differs from what was quoted due to incorrect length, width, and height or missing pallet weight. Using a density calculator LTL shippers trust helps reduce surprises and provides a more accurate estimate upfront.
