Imagine you want to ship two different products of different sizes but the same weight. The larger product will have higher shipping costs because, both weight and volume matter. Thus, carriers came up with dimensional weight calculations (DIM weight) that are based on product height, length, and width. The dimensional weight formula is:
DIM Weight = (L x W x H) / SF
If you use the DIM weight with large but light-weighted products, it will cost more than shipping based on the weight only. However, if you ship a small but heavy product, use DIM weight as it will be cheaper. Why? Because the DIM weight is less than the actual weight of the product. The advanced algorithm from DiM Weight is the type of
Smart Packaging which matches products and package dimensions.
