📦 Multi-Parcel Dimensional Weight Calculator

Estimate billable weight and shipping costs for multiple parcels.

Carriers may charge based on billable weight rather than actual weight. Billable weight is the greater of a parcel’s actual weight and its dimensional (DIM) weight. To calculate DIM weight, this tool rounds each parcel dimension up to the next whole unit before dividing the volume by the selected DIM divisor.

To use this tool:

Select metric or imperial units. All parcel groups in a calculation use the same unit system. Use a separate row for each parcel type. Group parcels together when they share the same dimensions, actual weight, DIM divisor, and price per unit; enter the number of parcels in the quantity field. Add another row for parcels with different values.

This tool is for estimation purposes only. Always verify specific dimensional weight rules and conditions directly with your carrier.
