The height of the Sears Tower has been widely and erroneously reported as 1,454 feet (443 metres). According to Skidmore, Owings & Merrill, the architectural firm in charge of designing the building, the correct height is 1,450 feet (442 metres). This is also the figure favoured by the Council on Tall Buildings and Urban Habitat (Lehigh University, Bethlehem, Pennsylvania).
The height of the Sears Tower including the aerial is 1,725 feet.
