Heighest Truck Height = T

The standard height for trailers is 55". You can use this figure as a reference point for standard trailer height. On refrigerated or container trailers, the standard height is 59".

T is the measurement from the ground to the bed of the trailer.

Dock Height = D

The dock height is calculated by measuring the distance from the ground to the top of the dock.

Height Differential (Maximum) = H

Truck Height(T) - Dock Height(D) = Height Differential (H)
