The girth measurement is a measure and is used by logistics companies. Before shipping parcels, the belt size is determined. This will ensure that the packages are acceptable for shipping due to their dimensions and which costs will be charged. For calculating the belt dimensions, there is the following belt measure formula:
The longest side plus twice the width plus twice the height.
When it comes to transporting goods, however, the restrictions are not just about the girth, but also the weight and the number of transmissions play a role and are different for each company. In the meantime, some companies no longer specify the permissible dimensions using the girth measure, but rather the maximum length, width, and height.
