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 R+L Carriers uses freight class
R+L Carriers is a family-owned national LTL carrier with its own line-haul network across the US, Canada, Puerto Rico and the Caribbean. Its LTL pricing follows the NMFC density scale: class, then weight and lane. Knowing your freight class before you quote R+L keeps the rate accurate and lets you compare it like-for-like against other carriers on the same shipment.
R+L Carriers' network and family ownership
R+L Carriers is a family-owned LTL carrier that runs its own line-haul network rather than heavily interlining, with coverage across the continental US plus Canada, Puerto Rico and the Caribbean. That owned network gives R+L direct control of more lanes — useful for shippers who want fewer handoffs — but the freight is still rated the standard way, on the NMFC density class.
R+L's LTL pricing follows the usual build: class first, then weight, lane and any accessorials. Because the class is the industry-standard number, calculating it here lets you drop R+L into an apples-to-apples comparison against other carriers on the exact same shipment, then choose on rate, transit and coverage rather than guessing at the classification.
Is R+L Carriers’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 R+L Carriers 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 R+L Carriers against other carriers on identical numbers with the freight quote builder.
Frequently asked questions
Does R+L Carriers 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 R+L Carriers or anyone else. R+L Carriers simply applies that class to its own rates and lanes.
How do I find my R+L Carriers 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 R+L Carriers when you book.
Why does freight class matter for a R+L Carriers quote?
Class is usually the single biggest factor in an LTL rate. R+L Carriers is a family-owned national LTL carrier pricing on standard NMFC freight class. Getting it right before you request a quote keeps the rate accurate and avoids a costly reclassification later.
Where does R+L Carriers deliver?
R+L runs its own line-haul network across the continental US, plus Canada, Puerto Rico and the Caribbean. Freight class is the same everywhere — calculate it here and request an R+L quote for your lane.
Is R+L Carriers a good option for LTL?
R+L is a family-owned national carrier with a largely owned network (fewer handoffs). It prices on standard NMFC freight class, so calculate your class and compare its rate and transit against other carriers on identical numbers.
