What Is a Loading Meter (LDM)?

A loading meter (abbreviated LDM, also written Lademeter in

German, Ladningmeter in Danish, or Lademetre in French) is a standardised unit

of trailer floor space. One LDM represents a strip of trailer floor that is

2.4 metres wide and 1.0 metre long —

matching the usable interior width of a standard European curtainsider trailer.

A standard European tarpaulin (curtainsider) semi-trailer measures

13.6 m long × 2.48 m wide × 2.75 m interior height. Its total usable

floor space is therefore 13.6 LDM. That is the baseline

against which every LTL groupage shipment is measured.

Why is LDM used instead of volume or weight? Volume-based

pricing (cubic metres) rewards carriers for heavy, dense cargo but penalises

them for light bulky goods. Weight-only pricing has the opposite problem.

LDM measures the floor footprint — what actually limits how many shipments fit

in a truck — which makes it the fairest and most practical unit for consolidation

(groupage) operations. In Europe, LDM pricing dominates LTL; parcel carriers use

volumetric weight, but pallet freight uses LDM.

LDM is sometimes called running meter or linear meter

in English-language logistics documentation, and you will see “ldm”, “LM”,

“RM” all used interchangeably on rate cards and invoices.

The LDM Formula — With Worked Examples

Stackable cargo. If your cargo can be safely stacked on top

of itself (e.g., two layers of boxes on a pallet), you can halve the LDM by

dividing by the number of stacking layers. Example: 10 EUR pallets in two

layers = 10 × 0.4 ÷ 2 = 2.0 LDM instead of 4.0 LDM. You

must declare stackability on your booking — false declarations invalidate

insurance coverage.

Irregular cargo. For non-rectangular cargo, use the bounding

box: measure the maximum length and maximum width of the footprint, even if the

cargo does not fill that rectangle entirely. Carriers charge for the space

reserved, not the exact silhouette.

The weight check. European LTL has a standard weight

allowance of approximately 1,750 kg per LDM. If your cargo is very dense, the chargeable LDM may be

determined by weight rather than physical footprint. Chargeable LDM = max

(physical LDM, total weight ÷ 1,750). Example: a 7-tonne machine on 3 LDM

— weight check: 7,000 ÷ 1,750 = 4.0 — so you are charged for 4.0 LDM

even though the footprint is only 3.0 LDM.

How Freight Prices Are Calculated from LDM

Once you know your chargeable LDM, the base freight cost is straightforward:

Base freight cost = Chargeable LDM × Rate per LDM

The rate per LDM varies by lane (origin–destination corridor), service level

(Economy, Standard, Express), and seasonality. For major corridors out of Spain,

indicative 2026 rates range from €38/LDM (Spain–France Economy) to over

€110/LDM (Spain–UK Express). See the country-pair table below for full detail.

Most carriers apply a minimum charge equivalent to 0.5 LDM

or 1.0 LDM regardless of actual cargo size. This prevents the economics of

groupage from breaking down for tiny shipments.

Frequently Asked Questions

What does LDM mean in European freight?

LDM stands for Loading Meter (also written Lademeter in German, or Lademetre in French). One LDM is the amount of trailer floor space occupied by a cargo unit that is 2.4 metres wide and 1 metre long. A standard European curtainsider trailer is 13.6 LDM in total. LDM is the primary pricing unit for LTL (Less than Truck Load) road freight across Europe.

How do you calculate LDM from pallet count?

Use the formula: LDM = (Length × Width × Quantity) ÷ 2.4. For a EUR pallet (1.2 m × 0.8 m): LDM = (1.2 × 0.8 × 1) ÷ 2.4 = 0.4 LDM per pallet. For an industrial pallet (1.2 m × 1.0 m): LDM = (1.2 × 1.0 × 1) ÷ 2.4 = 0.5 LDM per pallet. Multiply by the number of pallets and add any weight-equivalent adjustment if your cargo exceeds 1,750 kg per LDM.

What is a typical LDM freight rate from Spain to Germany?

For standard LTL groupage freight from Spain to Germany (e.g., Barcelona to Munich), the base rate in early 2026 is approximately €62–78 per LDM depending on service level (Economy, Standard, or Express). Add a fuel surcharge of 15–22% plus any applicable ADR, insurance, or zone supplements. A 4-LDM shipment (10 EUR pallets) would cost roughly €280–370 before surcharges, or €330–460 all-in.

When does FTL become cheaper than LTL/LDM pricing?

Full Truck Load (FTL) typically becomes more cost-effective than LTL groupage pricing when your shipment exceeds 8–10 LDM (roughly 20–25 EUR pallets) on major corridors. Below that threshold, LTL is almost always cheaper because you only pay for the floor space you use. Above 10 LDM, the fixed cost of a full truck is spread over enough cargo to undercut per-LDM groupage rates. Use the Transroad LDM calculator to compare both options simultaneously.
