Loading meter calculator (LDM)
Free loading meter calculator: convert pallets and packages into loading meters (LDM), account for stacking and check the utilization of truck/semitrailer. With explanation and optional AI cargo space optimization upon request.
What is a loading meter?
A Loading meter (LDM) is one linear meter of loading area across the full width of the cargo space (standard 2,40 m). It is the standard unit for calculating part loads and fairly allocating cargo space – regardless of the exact weight. A standard-Semitrailer offers around 13,6 LDM (approx. 33–34 Euro pallets on the floor).
The loading meters required per slot result from the pallet dimensions and the number placed side by side:
Total LDM = rounded-up slots × LDM per pallet (with stacking: slots = pallets ÷ layers)
| Pallet type | Dimensions | LDM per slot |
|---|---|---|
| Euro pallet | 120 × 80 cm | 0,40 |
| Industrial/CHEP | 120 × 100 cm | 0,50 |
| Düsseldorf | 80 × 60 cm | 0,20 |
Reference values for the standard LDM calculation. Non-stackable, oversized-width or oversized-height shipments may deviate.
