Calculating the volumetric weight of a package is essential before booking a shipment: shipping companies—GLS, SEUR, Correos, DHL, MRW—charge based on either the actual weight or the volumetric weight, whichever is greater. If you're sending a large but lightweight box, the cost will be determined by its dimensions, not its weight on the scale.
With this volumetric weight calculator you can enter the measurements of your box in centimeters and instantly obtain the volume in cubic meters, in liters and the volumetric weight according to the divisor factor of the main transport agencies in Spain and Portugal.
What is volumetric weight and why does it matter?
Volumetric weight is an equivalence that converts the size of a package into a nominal weight in kilograms. It is calculated by dividing the package's volume (length × width × height in cm) by a factor that varies depending on the carrier: 5,000 for most ground shipping companies, 6,000 for some international carriers. If the result exceeds the actual weight of the package, the carrier will charge based on the volumetric weight.
This explains why shipping a 60×40×40 cm box of lightweight clothing can be more expensive than expected: its volumetric weight is 19.2 kg even though the contents only weigh 5 kg. Choosing the right size box for your product reduces the volumetric weight and saves money on every shipment.
How to calculate the cubic volume of a box?
The cubic capacity, or volume in cubic meters, is obtained by multiplying the three interior dimensions of the box (length × width × height) and dividing by 1,000,000 if the measurements are in centimeters. A box measuring 40×30×30 cm has a cubic capacity of 0.036 m³. This information is useful for calculating how many boxes fit on a pallet, in a container, or in a storage unit.

Tips for reducing the volumetric weight of your shipments
- Use the tightest-fitting box possible: every extra centimeter increases the volume. A box that's 5 cm larger in each dimension can increase the cost by 30%.
- Fill the empty space: if you can't find the exact measurement, use kraft paper or packing chips to protect and prevent the carrier from resizing the box.
- Consider padded envelopes: for flat, lightweight products, a bubble envelope has zero volumetric weight at many agencies.
