- Enter weight: Total weight in pounds (include pallet weight)
- Get your class: The calculator computes density and assigns the NMFC class
Common Pallet Sizes and Weights
| Pallet Size | Common Weight | Notes |
|---|---|---|
| 48×40×48" | 500–1,500 lbs | Standard GMA pallet |
| 48×40×60" | 500–2,000 lbs | Tall stack |
| 48×48×48" | 500–2,500 lbs | Square pallet |
Why Accurate Dimensions Matter
LTL carriers routinely measure shipments with dimensioning systems. If your declared dimensions don't match, you'll face reclassification fees and a higher freight rate. Always measure the actual footprint including overhang, stacking height, and pallet dimensions.
Frequently Asked Questions
How do I find freight class from weight and dimensions?\u25BE
Calculate volume = (L×W×H) ÷ 1,728, then density = Weight ÷ Volume. Match density to the NMFC chart.
