Slab-to-Slab Height

The slab-to-slab height is the height between an interior space’s true ceiling and true floor.

The ‘true ceiling height’ or simply ceiling height is the distance between the floor and the area under the roof (i.e., not the lowest hanging object or “drop” ceilings). The true floor is the area’s lowest structural element, be it the floor or the concrete slab beneath the floor.
