ldm_calculator
Calculate loading metres (LDM) for European road freight shipments to determine trailer space usage and check pallet fit within vehicle limits.
Instructions
Calculate loading metres (LDM) for road freight shipments.
LDM measures how much of a trailer's length a pallet load occupies. European trailers are 13.6m long and 2.4m wide. LDM = (pallet_length x pallet_width x quantity) / (trailer_width x stack_factor).
Use this tool when you need to:
Quote European road freight (FTL/LTL)
Calculate trailer utilisation percentage
Check if pallets fit within vehicle weight/space limits
Supports pallet presets (euro, uk, half, quarter) or custom dimensions. Supports vehicles: artic (13.6m), rigid10, rigid75, luton, or custom length.
