About This Calculator

The Package Volume Calculator helps you determine shipping costs by calculating both actual weight and dimensional (DIM) weight. Carriers charge based on whichever is greater—this is called the "billable weight."

Why dimensional weight matters: Large, lightweight packages take up truck space without contributing much actual weight. DIM weight ensures carriers are compensated for the space used, not just the weight carried.

Enter your package dimensions and actual weight to see volume calculations, DIM weight across different carriers, and your expected billable weight. Use this to optimize packaging and reduce shipping costs.
