The containers that your personal goods will be packed into have all been standardized, too. If you are shipping household goods, you will almost certainly ship 20 ft container or ship 40 ft container. The 20 foot container is actually the basic unit size. Called "TEU" for Twenty-foot Equivalent Unit, it is the basic cubic foot measurement that all containers must adhere to. Container shipping companies measure all of their cargoes in these units and vessels are said to have capacities of numbers of TEUs.
