Combined length and girth is the alculation basis for the carriage by road. The combined length and girth serves as a dimensional reference for cargo loads and is measured on the basis of the parcel´s circumference in cm. If a parcel exceeds the limits specified by carriers, the shipping will be effected on the basis of the respectively applicable rate class. These maximum lengths differ from country to country, however, as a rule of thumb, they must not exceed a value of approx. 360cm (DHL) or 762cm (FedEx) or 400cm (UPS) and are absolutely sufficient for standard carriage.
