What Is Dimensional Weight (Desi) in Shipping and Why Is It Calculated?
In the logistics and transport sector, the load capacity of a vehicle (truck, plane) is limited not only by kilograms but also by internal volume. A very light but very large box can fill up the vehicle, causing losses for the company. To prevent this and ensure fair pricing, the 'volumetric weight' or dimensional weight system is used.
Dimensional Weight vs. Physical Weight (Kg)
Physical weight is the net kilogram (kg) value shown on a scale. Dimensional weight is the value mathematically calculated based on the box dimensions. When accepting a package, shipping companies look at both values and always use the higher of the two as the billing measure.
How Does the Dimensional Weight Formula Work?
Dimensional weight calculation is based on a standard formula determined by international and local transport regulations. The three basic dimensions of the cargo (length, width, height) are multiplied together and the resulting volume is divided by a fixed divisor determined by the transport mode (road, air) to arrive at the dimensional weight.
Domestic Cargo Dimensional Weight Divisor (3000)
The fixed divisor used in standard domestic road transport within Turkey is 3,000. The formula is: (Length × Width × Height) / 3,000. All measurements must be taken in centimetres (cm).
International and Air Cargo Dimensional Weight Divisor (5000 or 6000)
For packages sent internationally or via air freight, because space in an aircraft cargo hold is far more costly, the divisor is typically 5,000 (or 6,000 at some carriers) instead of 3,000. This calculation results in a higher dimensional weight compared to road transport.
