What is Shipping Desi? How to Calculate Volumetric Weight 2026

One of the most critical factors determining the cost of e-commerce shipments or personal parcels is the "desi" or volumetric weight. Understanding how to calculate this value correctly is essential for minimizing your shipping expenses.

Why Does Volumetric Weight Matter?

In logistics, shipping capacity is limited by both weight and the physical space a package occupies. A very light but large parcel takes up significant room in a delivery vehicle, reducing overall efficiency. To balance this, couriers charge based on either the "actual weight" or the "volumetric weight (desi)"—whichever is higher.

The Volumetric Weight Formula

To determine the desi value of your parcel, use the following standard formula: Formula: (Width x Length x Height) / Divider

Calculation Standards (Dividers)

The "divider" used in the formula varies depending on the type of shipment and the courier:

• Domestic Shipments: Often use a divider of 3000.
• International Shipments: Typically use the global IATA standard divider of 5000.

Step-by-Step Calculation Example

Suppose you have a box measuring 60 cm x 40 cm x 20 cm:

1. Find the Volume: 60 x 40 x 20 = 48,000 cm³
2. Divide by Standard (International): 48,000 / 5000 = 9.6 Desi

If this package weighs 5 kg, you will be billed for the higher value, which is 9.6 Desi. If the actual weight is 12 kg, you will be billed for 12 kg.

Frequently Asked Questions (FAQ)

Which dimensions should I measure for shipping?

Always measure the widest points of the package, including any handles, wheels, or bulges created by the contents.

Why do some couriers use 3000 and others 5000?

The 3000 divider is common for domestic ground transport in specific regions, while the 5000 divider is the industry standard for international air freight worldwide.

How can I reduce my shipping desi?

You can reduce the desi value by choosing the smallest possible box that safely protects your item, avoiding unnecessary padding, and using flexible packaging when appropriate.
