Calculating the volumetric weight of a package is essential before contracting a shipment. Agencies such as GLS, SEUR, Correos, DHL, or MRW may charge based on the actual weight or the volumetric weight, whichever is greater.
With this calculator, you can enter your box's measurements in centimeters and instantly obtain the volume in liters, the cubic footage in cubic meters, and the volumetric weight according to the selected divisor factor.
What is volumetric weight and why does it matter?
Volumetric weight transforms the size of a package into billable kilograms. It is calculated by dividing the package's volume, length × width × height in centimeters, by a divisor factor. If this result exceeds the actual weight, the carrier may charge by volume.
This is why a 60 × 40 × 40 cm box with light clothing can cost more than expected: with a factor of 5000, its volumetric weight is 19.2 kg, even if the contents weigh only 5 kg. Choosing the right size box helps reduce costs on every shipment.
How to calculate the cubic footage of a box?
Cubic footage in cubic meters is obtained by multiplying the three interior dimensions of the box and dividing by 1,000,000 when the measurements are in centimeters. A 40 × 30 × 30 cm box has 36,000 cm³, which is 36 liters or 0.036 m³.
Divisor factors by carrier
Divisors may vary by contract, country, and service. This table serves as a general reference for reviewing your rates.
| Carrier | Common divisor factor | Service type |
|---|---|---|
| SEUR | 5,000 | National |
| GLS | 5,000 | National |
| MRW | 5,000 | National |
| Correos Express | 5,000 | National |
| DHL Express | 5,000 | International |
| UPS | 5,000 | International |
| FedEx | 5,000 | International |
Tips to reduce the volumetric weight of your shipments
- Use the snuggest box possible: every extra centimeter increases the volume and can raise the cost.
- Fill empty space: if you can't find the exact size, use kraft paper or packing peanuts to better protect the product.
- Consider padded envelopes: for flat and light products, a bubble padded envelope can be more efficient than an oversized box.
Frequently asked questions about volumetric weight
What is the difference between actual weight and volumetric weight?
Actual weight is what the scale shows. Volumetric weight is calculated using the package's dimensions. Many carriers charge based on the greater of the two values.
How is the cubic footage of a box calculated?
Multiply length × width × height in centimeters and divide by 1,000,000. For example, 50 × 40 × 30 cm is 60,000 cm³, which is 0.06 m³.
What divisor factor do carriers in Spain use?
Many national agencies use 5,000 as a reference, although it may change by contract or service. Some economy or international shipments may apply 6,000, and certain contracts may use 4,000.
How to reduce volumetric weight costs?
The key is to use a box proportional to the product. It also helps to protect without oversizing and to choose padded envelopes for flat or less bulky items.
Can I calculate non-standard boxes?
Yes. Enter the actual interior measurements, even if it's a custom, recycled, or special format box. If you need an exact measurement, consult our custom cardboard box service.
