 By charging only by weight, lightweight, low-density packages become unprofitable for freight carriers due to the amount of space they take up in trucks, aircraft, and ships in proportion to their actual weight.By using dimensioning technology to calculate an item's dimensional weight, carriers are able to charge based on either volume or weight, depending on which is greater.In the warehousing industry, dimensioning is used to provide an overview of the volume items in stock which can reduce the costs of materials, return handling, shipping and manpower.
