While M&S Trailers carry odd-length trailers as well, these are the most common sizes of road and storage trailers:
LENGTH X WIDTH
28′ x 8′
45′ x 8′
48′ x 8′
48′ x 8.5′ (102 inches)
53′ x 8.5′ (102 inches)
Most trailers between 28′ – 48′ are 8′ wide (exterior). The 53′ and some 48′ trailers are 8.5′ (or 102 inches) at the exterior.
Overhead door trailers have garage-style tracks and roller panels. This type is frequently used for trailers at loading docks, as the doors and be opened and closed without requiring the trailer to be moved from the dock.
Swing or barn-style doors are most frequently used for freight applications, as they have fewer moving parts and tend to be more resilient to wear & tear.
