Dimensional Weight Calculator
Carriers bill on whichever is greater: actual weight or dimensional (DIM) weight. Enter your package size and weight to see the billable weight.
What is dimensional weight?
DIM weight accounts for how much space a package takes up. It equals length × width × height divided by a carrier's DIM divisor. Light, bulky shipments are usually billed on DIM weight.
Which divisor should I use?
Most US domestic ground and air uses 139. International and older contracts often use 166. Always confirm the divisor in your specific carrier agreement.
Estimates are for planning only. Confirm rates, accessorials, minimums, and service details directly with providers.
What to do next
Knowing your billable weight, compare parcel and LTL options and ask brokers how they rate dimensional weight and accessorials on your lanes.
