The length of a bed rails plays an essential role in its compatibility with the toddler bed.
It is true and known by most parents that toddler beds are usually 52 inches long. However, it is recommended not to assume and instead measure your toddler's bed before going bed rail shopping since some toddler beds might not stand true to the generalized 52-inch number. In addition, the overall length of the toddler bed bumper or rail also depends on the type of rail being purchased. For example, a fixed bed railing will always be shorter than a swing down rail because it does not swing down. Overall height and thickness of the mattress also influence the ideal length of a toddler bed rail.
