Dimensional Weight Calculator
Carriers bill you on whichever is greater: actual weight or dimensional weight. Enter your box and see which one applies — and how much you are paying to ship empty space.

Your product (optional)
Add your product size to see how much of the box is empty air, and what a right-sized box would cost.

Divisors vary by carrier, service and region, and they change. Confirm the divisor in your own carrier contract before using these figures to check an invoice.
