Cubic Feet in Shipping: Meaning and How to Calculate

In plain English

Carriers use cubic feet to work out density, which affects class and price. International shipping uses cubic meters (CBM): one cubic meter is about 35.3 cubic feet.

Measure at the widest and tallest points, including any overhang or packaging.

Why it matters when you ship

Cubic feet affect your density and your class. An underestimate on the bill of lading is a common cause of re-measurement and additional charges.

Example

A crate measuring 60 by 40 by 36 inches has 86,400 cubic inches, which is 50 cubic feet.
