The interior dimensions of a 53-foot trailer are 630 inches x 102 inches x 110 inches (length x width x height). The driver cabin is not included in this dimension.
The 53-foot trailer is the largest available for use with a semi truck. If the cargo load is not big enough to warrant this size, the trailers are also available in 28-, 45- and 48-foot sizes. Choosing the right size load for a cargo is an important part of managing shipping costs. Additional questions about the size and cargo capacity of any given simi-truck can be acquired by contacting the trailer provider, as this information will slightly vary.
