Dimensional weight, nicknamed DIM weight, is an alternate formula used by couriers to determine an item’s shipping weight. Also known as “volumetric weight,” DIM weight accounts for how much physical space your package occupies rather than merely its weight on the scale.
If you’ve shipped items at any point since 2015, you know DIM weight and its potential to drive up shipping costs all too well. That’s especially the case if you have a light item in a large box, as couriers calculate both traditional weight and DIM weight, then charge you based on the higher number.
The introduction of DIM weight has transformed how both B2B and B2C companies think about packaging. Overlooking a package’s size in relation to the product inside can increase shipping costs significantly, even if the package is fairly light when placed on the scale. Although it may seem like a purely cost-driven consideration, optimizing your package’s DIM weight also has sustainability implications. In our current landscape, where sustainability matters to consumers, retail partners, C-suites, and government bodies more than ever before, any measure that saves costs and enhances environmental impact is a major win.
