Volume and Volumetric Weight Calculator
Enter the internal measurements of your box and instantly calculate liters, cubic meters, volumetric weight, and estimated billable weight.
Quick Calculation
Choose a size or enter your own
Use centimeters for dimensions. You can write decimals with a comma (e.g., 38,5). Actual weight is optional and helps estimate what weight would be charged.
Common Sizes
The divisor changes depending on the agency, service, and contract. The value 5000 is usually used as a reference for many shipments.

Calculating the volumetric weight of a package is essential before contracting a shipment. Agencies like GLS, SEUR, Correos, DHL, or MRW may charge based on actual weight or volumetric weight, whichever is greater.
With this calculator, you can enter your box measurements in centimeters and instantly obtain the volume in liters, the cubic capacity in cubic meters, and the volumetric weight according to the chosen divisor factor.
What is volumetric weight and why does it matter?
Volumetric weight converts 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.
That's 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 content weighs only 5 kg. Choosing the right size box helps reduce costs on every shipment.
How to calculate the cubic capacity of a box?
The cubic capacity in cubic meters is obtained by multiplying the three internal 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 checking 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 volume and can raise costs.
- 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 may 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 are the cubic meters 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, or 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 cost?
The key is to use a box proportionate to the product. It also helps to protect without oversizing and choose padded envelopes for flat or low-volume items.
Can I calculate non-standard boxes?
Yes. Enter the actual internal measurements, even if it's a custom box, recycled, or special format. If you need an exact measurement, check our custom cardboard boxes service.
