Loading meters (LDM) are the universal pricing unit for European LTL road freight. Whether you are shipping two pallets from Barcelona to Munich or a partial load from Madrid to Warsaw, understanding how to calculate LDM — and how carriers convert that figure into a price — is the single most valuable skill a European shipper can have. This guide explains the formula, shows real examples, and tells you exactly where to get an accurate rate in under 60 seconds.
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 meterin English-language logistics documentation, and you will see “ldm”, “LM”, “RM” all used interchangeably on rate cards and invoices.
LDM = (Length × Width × Quantity) ÷ 2.4
Length and Width in metres. Quantity = number of cargo units at that size. Divide by 2.4 (standard trailer interior width in metres).
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 (some carriers use 1,850 kg/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.
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.
Worked example — 6 EUR pallets, Spain to Germany, Standard LTL:
Physical LDM: (1.2 × 0.8 × 6) ÷ 2.4 = 2.4 LDM. Weight: 1,800 kg. Weight check: 1,800 ÷ 1,750 = 1.03 LDM — physical wins. Base rate Spain–Germany Standard: €70/LDM. Base cost: 2.4 × €70 = €168. Fuel surcharge at 19%: +€31.92. Total: approx. €200.
| Pallet Type | Dimensions (L × W) | LDM per Unit | Typical Max Weight | Common Markets |
|---|---|---|---|---|
| EUR pallet (EPAL) | 1.2 m × 0.8 m | 0.40 | ≤ 750 kg | Most common in Europe |
| Industrial / ISO pallet | 1.2 m × 1.0 m | 0.50 | ≤ 1,000 kg | Common in DE, NL, UK |
| Half pallet | 0.8 m × 0.6 m | 0.20 | ≤ 375 kg | Retail / display use |
| Quarter pallet | 0.6 m × 0.4 m | 0.10 | ≤ 175 kg | FMCG, impulse displays |
| UK pallet (full) | 1.2 m × 1.0 m | 0.50 | ≤ 1,000 kg | Same dims as industrial |
| UK pallet (half) | 1.2 m × 0.5 m | 0.25 | ≤ 500 kg | UK distribution |
| Düsseldorf pallet | 0.8 m × 0.6 m | 0.20 | ≤ 350 kg | Beverages, DE/NL |
| 2× EUR side-by-side | 1.2 m × 1.6 m | 0.80 | ≤ 1,500 kg | When width exceeds 0.8 m |

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.
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.
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.
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.
