How to properly measure the inside height of commercial real estate property.

Clear Height:

Distance from the floor to the lowest hanging ceiling member or hanging objects, beams, joists or truss work descending down into a substantial portion of the industrial work area. This is the most important measure of the interior height of an industrial building because it defines the minimum height of usable space within the structure. (Synonyms: Clear Headway, Clearance)

Ceiling Height:

Distance from the floor to the inside overhead upper surface of the room. This measure will be higher than any hanging objects, beams, joists or truss work, unless there is a dropped ceiling.

Truss Height:

Distance from the floor to the bottom edge of any truss used to support the ceiling or roof of a building. If there are hanging objects, beams or joists below the truss, the clear height will be lower then the truss height.
