LDM and CBM measure different constraints: LDM describes occupied loading length on the trailer floor, while CBM describes cubic cargo volume. One cannot be converted reliably into the other without assumptions about width, height and stacking.
Quick reference
A CBM-to-LDM conversion is only an estimate because it must assume usable trailer width, loaded height and how efficiently the cargo occupies that space.
Practical guide
Use this reference to answer one specific loading question, then verify the real pallet, trailer and legal vehicle limits before dispatch.
Planning conventions such as 0.40 LDM per EUR pallet or a 2.4 m reference width are useful shortcuts, not guarantees of physical fit, payload or legal compliance.
How it works
Read the definition first, apply the shown planning relationship only to matching cargo or equipment, and keep floor space, volume and weight as separate constraints.
When to use it
Use LDM for floor-space pricing or non-stackable freight; use CBM when volume is the meaningful capacity measure. Keep both when either floor space or volume can become limiting.
What to check before dispatch
A CBM-to-LDM conversion is only an estimate because it must assume usable trailer width, loaded height and how efficiently the cargo occupies that space.
Worked example
Example: 24 CBM cannot tell you the LDM by itself. With 2.4 m usable width and 2.0 m assumed loaded height, the estimate is 24 ÷ (2.4 × 2.0) = 5.0 LDM.
Common mistake
The main mistake is treating CBM and LDM as interchangeable units. They describe different geometry and only become related after you add loading assumptions.
FAQ — LDM vs CBM
What does this reference actually tell me?
Use this page as a quick planning reference. It summarizes a common nominal value or relationship; it does not certify a specific pallet, trailer, vehicle or shipment.
When is this useful in freight planning?
Apply the value only when the cargo or equipment matches the stated assumptions. For a real load, confirm the actual dimensions, orientation and usable space.
What must I verify before dispatch?
No. Nominal dimensions and planning factors can vary with equipment, body design, manufacturer, load arrangement and operating rules.
What is the most common mistake?
A common mistake is treating a reference value as a guaranteed physical fit or legal capacity. Use it as a first check, then verify the actual vehicle and load.
