About this tool
Enter the size of one product, how many go in a parcel, and the boxes you have. The calculator tries every orientation and arrangement, shows which boxes fit, how full they are, and works out volumetric weight with your courier's divisor (commonly 5000 for cm). The chargeable weight is the greater of actual and volumetric weight. It packs identical items in a regular grid, so real packing with irregular items may differ.
Shipping Box Selector and Volumetric Weight Calculator is part of ToolStack Hub's Calculators. It runs entirely in your browser, which keeps your data private and makes results instant. There is nothing to install, no account to create and no usage limit.
