How freight class is calculated (density scale)
Freight class is set by density = weight (lb) ÷ volume (ft³). Higher density → lower class → typically lower cost. Volume here is L × W × H × quantity.
| Density (lb/ft³) | Class |
|---|---|
| 50+ | 50 |
| 35 – 50 | 55 |
| 30 – 35 | 60 |
| 22.5 – 30 | 65 |
| 15 – 22.5 | 70 |
| 13.5 – 15 | 77.5 |
| 12 – 13.5 | 85 |
| 10.5 – 12 | 92.5 |

| 5 – 6 | 175 |
| 4 – 5 | 200 |

How Old Dominion uses freight class
Old Dominion is known for fast transit times and one of the lowest cargo-claims ratios in the LTL industry, which is part of why it commands premium rates. Those rates are still built on freight class, weight and lane. Because ODFL prices on the same NMFC density scale as everyone else, the class you calculate here is the class ODFL will use — confirm the NMFC item with them when you book.
Why Old Dominion costs more — and when it's worth it
Old Dominion consistently posts one of the lowest cargo-claims ratios in the industry — well under 1% of shipments — alongside high on-time performance and fast, mostly single-line-haul transit. That reliability is why ODFL commands premium rates: you're paying for freight that arrives on time and undamaged. For fragile, high-value or deadline-critical loads, that premium often pays for itself in avoided claims and missed-delivery costs.
None of it changes how your shipment is classified. ODFL rates on the same NMFC density scale as every other carrier — class, weight, lane, accessorials — so the class you calculate here is exactly what ODFL uses. The real question isn't “is ODFL's class higher” (it isn't) but “is ODFL's rate-per-class and service level worth the premium for this shipment.”
Is Old Dominion’s freight class different?
No — and this trips a lot of shippers up. Freight class is set by the NMFC density scale, a single national standard. The class you calculate here is the same one Old Dominion will rate against; what differs between carriers is the rate per class, the lanes they serve, and their accessorial fees — not the class itself. So calculate once, then compare Old Dominion against other carriers on identical numbers with the freight quote builder.
Frequently asked questions
Does Old Dominion use a different freight class than other carriers?
No. Freight class comes from the NMFC density scale, which is an industry standard — so the class for your shipment is the same whether you ship with Old Dominion or anyone else. Old Dominion simply applies that class to its own rates and lanes.
How do I find my Old Dominion freight class?
Measure your shipment's dimensions and weight, work out the density (weight ÷ volume), and match it to the NMFC scale — the calculator above does exactly that. Confirm the final class and NMFC item number with Old Dominion when you book.
Why does freight class matter for a Old Dominion quote?
Class is usually the single biggest factor in an LTL rate. ODFL is a premium LTL carrier (low claims, fast transit); it prices on standard NMFC freight class. Getting it right before you request a quote keeps the rate accurate and avoids a costly reclassification later.
Why is Old Dominion more expensive than other LTL carriers?
ODFL charges a premium for reliability — one of the lowest cargo-claims ratios in the industry, high on-time performance and fast transit. Its freight class is the standard NMFC class; the premium is in the rate-per-class and service, not the classification.
Is Old Dominion good for fragile or high-value freight?
It's a common choice for it, thanks to a very low damage/claims record and fast transit. You still calculate the same NMFC freight class — the value is the careful handling and on-time reliability behind that class.
