An office building of three stories is about 38.39 feet tall. A three-story residential building is about 30 feet tall. A mixed-use building with three stories is about 34.5 feet tall.

The Council of Tall Buildings and Urban Habitat calculates the heights of buildings by first allocating them to one of three categories: office buildings, residential buildings and hotels, and mixed-use buildings. The floor to floor height of an office building is 3.9 meters per story, or almost 13 feet. Residential buildings tend to have floor heights of about 3.1 meters, or 10 feet per story, and mixed-use edifices’ floor heights are about 3.5 meters, or 11.5 feet per story.
