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 |

How Estes uses freight class
Estes is the largest privately held LTL carrier in the United States, with a broad national network and a full range of LTL, volume and time-critical services. Whichever service you use, the rate starts from your freight class, weight and lane. Calculating the class first means your Estes quote reflects your real shipment and won't be adjusted by a later reclassification.
Estes: the largest privately held LTL carrier
Estes Express Lines has been family-owned since Webb Estes founded it in 1931, and it has grown into the largest privately held LTL carrier in the United States — a national network without the quarterly-earnings pressure of its public rivals. For shippers that shows up as a broad direct footprint and a full menu of services: standard LTL, volume and partial loads, and time-critical guaranteed delivery.
Whichever Estes service you pick, the rate is built from your freight class, weight and lane. Volume and partial-load pricing can beat standard LTL once a shipment gets large enough, but class still anchors the quote — so calculate it here first, then ask Estes whether a volume rate beats the class-based LTL rate for your load.
Is Estes’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 Estes 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 Estes against other carriers on identical numbers with the freight quote builder.
Frequently asked questions
Does Estes 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 Estes or anyone else. Estes simply applies that class to its own rates and lanes.
How do I find my Estes 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 Estes when you book.
Why does freight class matter for a Estes quote?
Class is usually the single biggest factor in an LTL rate. Estes is the largest privately held US LTL carrier; freight class is the base of every Estes LTL rate. Getting it right before you request a quote keeps the rate accurate and avoids a costly reclassification later.
Is Estes a good LTL carrier?
Estes is the largest privately held US LTL carrier, with a broad national network and services from standard LTL to volume and time-critical. It rates on the standard NMFC freight class like every carrier — calculate yours above before quoting.
Does Estes handle volume or partial truckloads?
Yes — Estes offers volume and partial-load LTL that can beat standard rates once a shipment is large enough. Freight class still anchors the quote, so calculate it first and compare.
