What is dimensional weight?

Dimensional weight (also called volumetric weight) is a pricing technique used by carriers. It calculates weight based on package volume rather than actual weight, ensuring fair pricing for lightweight but bulky items.

What divisor should I use?

Air freight typically uses ÷6000 (IATA standard). Express carriers like DHL, FedEx, and UPS use ÷5000. Some EU carriers use ÷7000. US domestic shipping uses 139 (inches/pounds).

How is chargeable weight determined?

Chargeable weight is the greater of actual weight and dimensional weight. Carriers always charge based on whichever is higher.
