| Shipment | Dimensions | Weight each | Qty | Density (lb/ft³) | Suggested class |
|---|---|---|---|---|---|
| A | 48×40×50 in | 250 lb | 1 | 36.0 | 55 |
| B | 60×48×60 in | 300 lb | 1 | 18.0 | 70 |
| C | 120×40×40 in | 180 lb | 1 | 4.7 | 200 |
| D | 100×120×140 cm | 180 kg | 2 | 11.5 | 92.5 |
Density is the quickest variable carriers use to judge space efficiency. If freight averages 10 lb/ft³, a 53‑ft trailer can cube out near 3,500 ft³ long before it hits typical weight limits. This calculator converts measured cube and weight into density and a practical class suggestion for first-pass pricing. For example, 1,000 lb at 100 ft³ equals 10 lb/ft³.
Re‑class disputes often begin with inconsistent measurements between shipper and terminal. Measure the outer footprint, not product size, and include pallets, dunnage, corner boards, and stretch wrap. Adding just 2% to each dimension increases cube about 6%, which can move a shipment across a density band and change charges. Measure at widest points and record photos for verification.
Many cartons and crates include void space for protection. If freight occupies only 85% of its external cube, the effective density is lower than scale weight implies. The occupancy option models that gap by dividing volume by the occupancy factor, producing an apples-to-apples density that better matches how freight consumes trailer space. Useful for irregular shapes and partially filled crates.
Shipping teams often mix inches, centimeters, pounds, and kilograms across systems. This tool calculates in both units, showing per‑piece and total figures for weight and volume. Consistent units prevent quoting errors when warehouse data, supplier specs, and forwarder paperwork disagree, and they simplify handoffs between origin and destination teams. Dual outputs help populate bill-of-lading fields.
The density-to-class table is a proven starting point for LTL quoting, but it is not the final authority. Commodity descriptions, stowability, handling, and liability can override a density estimate. Use the suggested class to shortlist options, then confirm the correct NMFC item and any carrier rules that apply to packaging or dimensions. When uncertain, request a carrier inspection or a classification ruling.
Quoting and dispatch require sharing the same numbers across sales, operations, and carriers. The CSV export supports spreadsheet and TMS workflows, while the PDF report provides a clean attachment for rate requests and booking emails. Keeping cube and density records helps audit invoices, explain accessorials, and reduce surprises during billing reviews. Exports make internal approvals faster and create a repeatable quote trail.
No. It is density-based guidance for early quoting. Final class depends on the correct NMFC item and rules for stowability, handling, and liability, which can override density.
Use packaged outer dimensions. Include pallets, skids, shrink wrap, corner protection, and any overhang. Carriers rate the space you occupy, not the product’s bare size.
Occupancy adjusts effective volume when the cube is not fully utilized. Lower occupancy increases effective volume and lowers density, which may raise the suggested class for bulky freight.
Allowance accounts for real-world variability like wrap thickness, pallet overhang, or measurement rounding. Small increases can shift density bands, so allowance helps you quote more conservatively.
Calculate each item type separately, then combine totals if they share the same handling unit. If items ship on separate pallets, treat each pallet as its own piece for best accuracy.
It is designed for freight density and class guidance used in LTL workflows. Parcel carriers typically rate by dimensional weight formulas rather than NMFC density classes.
