Dimensional Weight Calculator
Estimate dimensional weight from the outside package dimensions, compare it with actual weight, and see the higher estimated billable weight.
Carriers may round dimensions, apply service-specific divisors, use different thresholds or add oversize charges. Treat this as a planning estimate and verify current carrier rules before shipping.
Why dimensional weight matters
A large lightweight package can take up more truck or aircraft space than its scale weight suggests. Dimensional weight converts package volume into a weight value so space usage can be considered when estimating charges.
Use the packed outside dimensions
Measure the final sealed package, not the product or the nominal inside box size. Carrier measurement and rounding rules can differ, so always check the current service guide when a shipment is close to a limit.
