A 53-foot trailer holds 3816 cubic feet of air (8' wide by 9' high by 53' long). The floor space on an 8' x 53' trailer would be 424 sq. ft.
The total square footage inside a 53 foot semi trailer is about 3,400 square feet. This space can only be fully occupied if the semi truck and trailer weight combined is 80,000 pounds or less. Federal law regulates how much a loaded semi truck and trailer can weigh. There are also limits on axle weight to arrive at this total. It is 12,000 for steer tires, 34,000 for drives, and 34,000 for tandem axles.
