Dimensional Weight Calculator

Calculate dimensional weight (desi) from package length, width, and height to determine billable shipping weight.

Frequently Asked Questions

What is dimensional weight (desi)?

Desi is a billing unit derived from package dimensions used by carriers when volume exceeds actual weight.

What is the desi formula?

(Width × Length × Height) / divisor. Example: 40×30×20 cm with divisor 3000 equals 8 desi.

Which divisor should I choose?

Use 3000 for standard domestic rules and 5000 for express/international—follow your carrier tariff.

How is desi different from actual weight?

Actual weight is measured in kg; desi is volume-based. Carriers charge the higher of the two.

Why does desi matter in e-commerce?

Bulky lightweight SKUs can be billed on desi, impacting margins and shipping strategy.

Should dimensions be in centimeters?

Yes. Enter width, length, and height in cm. Convert other units before calculating.

What is volume used for?

Volume (cm³) helps with box selection and warehouse planning alongside desi.

Are results legally binding?

No. They are estimates; final billing follows carrier measurement.

Is the desi calculator free?

How do I estimate shipping cost next?
