Understanding how package size affects shipping costs.
Dimensional weight, also known as DIM weight, reflects a package's density — the amount of space it occupies in relation to its actual weight. Shipping carriers use the greater of the two (actual weight vs. dimensional weight) to calculate shipping costs.
If you have a large but lightweight package, it might cost more to ship because of the space it takes up in a truck or airplane. Understanding this concept helps you optimize your packaging and save on shipping fees.
