Need Linear dimensions (L+W+H), Volumetric weight, Chargeable weight? The Luggage Allowance & Volumetric Weight Guide derives it from Length (cm), Width (cm), Height (cm), Actual weight (kg) in one step. For instance, with Length (cm) = 55, Width (cm) = 40, Height (cm) = 23 and Actual weight (kg) = 10 it returns Linear dimensions (L+W+H) = 118 cm, Volumetric weight = 10.12 kg and Chargeable weight = 10.12 kg.

How to use it

  1. Enter your values: Length (cm), Width (cm), Height (cm), Actual weight (kg).
  2. Read the result instantly: Linear dimensions (L+W+H), Volumetric weight, Chargeable weight.

Frequently asked questions

How does the Luggage Allowance & Volumetric Weight Guide work?

It takes Length (cm), Width (cm), Height (cm) and Actual weight (kg) and derives Linear dimensions (L+W+H), Volumetric weight and Chargeable weight from them. The calculation is live as you type, so the result updates on every change.

Which values does the calculator ask for?

4 values: Length (cm), Width (cm), Height (cm) and Actual weight (kg). Nothing else is required — no account, no file upload.

What does a typical calculation look like?

With Length (cm) = 55, Width (cm) = 40, Height (cm) = 23 and Actual weight (kg) = 10, the calculator returns Linear dimensions (L+W+H) = 118 cm, Volumetric weight = 10.12 kg and Chargeable weight = 10.12 kg. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

How much does the result change with different inputs?

It moves a lot. Using Length (cm) = 61, Width (cm) = 44, Height (cm) = 25 and Actual weight (kg) = 11 instead, Linear dimensions (L+W+H) goes from 118 cm to 130 cm — which is why it is worth testing a few scenarios rather than trusting a single figure.

What does it give for smaller values?

Scaled down to Length (cm) = 50, Width (cm) = 36, Height (cm) = 21 and Actual weight (kg) = 9, Linear dimensions (L+W+H) comes out at 107 cm. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Deciding between two cars, or between keeping one and replacing it: fuel or charging, insurance, depreciation and what a kilometre really costs.

What is the most common mistake?

Comparing on fuel alone. Depreciation is usually the largest line in the first years and dwarfs the difference in consumption between two comparable cars.

How accurate is it, and what are the limits?

Volumetric divisor and limits vary by airline — check the carrier's baggage policy.

What is the difference between the Luggage Allowance & Volumetric Weight Guide and the Trailer Tongue Weight Calculator?

This one returns Linear dimensions (L+W+H) and Volumetric weight; the Trailer Tongue Weight Calculator returns Result. That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Vehicle Weight Distribution Calculator is the closest one after this: Split a vehicle's weight front/rear from a total and balance or from axle weights, get the CG position from the wheelbase and the left/right cross balance.

Tongue weight tells you whether the combination will stay straight.
