What is volumetric weight?
Volumetric weight, also called dimensional weight, is a way for courier companies to price a parcel by the space it takes up in a van, truck or aircraft — not only by its actual weight.
Large but lightweight parcels can cost more to ship because they use more transport space. Use the calculator above to estimate your parcel’s volumetric weight, then compare delivery options with Ecoparcel.
Volumetric weight formula: quick answer
Volumetric weight formula: Length × Width × Height ÷ volumetric divisor = volumetric weight.
If you measure the parcel in centimetres, many courier services use a divisor such as 5000 or 6000, depending on the service and route. The courier usually charges for the higher value: the parcel’s actual weight or its volumetric weight. This is called the chargeable weight.
Example: a parcel measuring 50 × 40 × 30 cm has a volume of 60,000 cm³. With divisor 5000, the volumetric weight is 12 kg.
How to calculate volumetric weight
Measure the parcel’s length, width and height at the widest points. Multiply the three dimensions and divide the result by the courier’s volumetric divisor.
Different couriers and services may use different divisors, so the calculator gives an estimate. The final price is confirmed during booking when available courier options are compared.
Actual weight vs volumetric weight
Actual weight is what the parcel weighs on a scale. Volumetric weight estimates how much transport space the parcel uses. Couriers normally use the higher of the two values as the chargeable weight.
This is why a box of pillows may cost more than expected, while a compact heavy parcel can be priced closer to its actual weight.
How to measure your parcel correctly
Measure the finished parcel after it is packed, not the item before packing. Include handles, bulges, tape, protective layers and any uneven parts.
Round dimensions up rather than down. Incorrect measurements can lead to courier surcharges, delays or a failed collection.
How to reduce volumetric weight costs
Choose the smallest strong box that safely protects the item. Avoid oversized packaging, remove empty space where possible and use protective materials that do not add unnecessary volume.

Volumetric weight FAQ
Is shipping charged by actual weight or volumetric weight?
Most couriers charge by the higher value: actual weight or volumetric weight.
What is chargeable weight?
Chargeable weight is the weight used to calculate the shipping price. It is usually the higher of actual and volumetric weight.
Do all couriers use the same divisor?
No. Divisors can vary by courier, route and service type, so always check the final quote before booking.
