Shipping
Dimensional Weight Calculator
Compute the billable weight of a shipment as the greater of actual weight or dimensional (volumetric) weight, using the carrier-specific DIM divisor. Useful for FedEx, UPS, USPS, and DHL parcels where bulky-but-light packages get charged on volume rather than mass.

Shipping
Package Optimization Calculator
Estimate the total packaging cost — both surface material and volume-based filler — for a box sized to fit a specific item with safety padding. Useful for finding the lowest-cost packaging that still protects goods and minimizes dimensional weight.
