Frequently Asked Questions

Dimensional Weight = (Length × Width × Height in cm) ÷ 5000. This is the standard divisor used by FedEx, DHL, and most Indian couriers for air shipments.

Couriers charge on whichever is higher: your package's actual weight, or its dimensional weight. This calculator shows both and reports the higher one as your billable weight.

If a package is bulky but light (e.g. a large, empty-feeling box), its dimensional weight can exceed its actual weight — you'd be billed on the larger dimensional figure, not the lighter actual weight.

It's the common standard for air freight, used by FedEx and DHL among others — but some couriers or shipment types (e.g. sea freight) use a different divisor. Confirm your specific courier's divisor if the estimate seems off.
