La ville de Downtown Chicago ou le long de la Michigan Avenue. Par ailleurs, Chicago est la seule ville du monde, à posséder au moins deux bâtiments de plus de 100 étages (New York en possédait 3 jusqu'au 11 septembre 2001). Le John Hancock Center, avec des étages de condominiums entre des étages de bureau et des étages de restaurants, constitue la zone résidentielle la plus élevée du monde.

La tour Sears est aussi la tour possédant le plus d'étages dans le monde<ref>[http://skyscraperpage.com/diagrams/?31982415]"''Diagramme des plus hauts gratte-ciels du monde basé selon leur nombre d'étage''" Dernier accès le 19 novembre 2007.</ref>, et la plus haute tour du Monde si on prends pour mesure sa hauteur plus son antenne de plus de 100m.<ref>[http://skyscraperpage.com/diagrams/?31982397] "''Diagramme des plus hauts gratte-ciels au monde incluant l'antenne''" Dernier accès le 19 novembre 2007.</ref>

Plusieurs gratte-ciel sont en construction ou programmés. La Chicago Spire dont la construction devrait commencer en 2007, doit mesurer plus de 600 mètres et comprendre 150 étages. Elle dépasserait donc la Sears Tower et deviendrait la plus haute tour du pays. 

La ville compte aussi au moins 89 gratte-ciels (édifices d'une hauteur d'au moins 152 mètres ou 500 pieds) à l'intérieur de ses frontières<ref>[http://skyscraperpage.com/diagrams/?31949868] "''Diagramme des gratte-ciels de Chicago''" Dernier accès le 19 novembre 2007.</ref>, deuxième en Amérique du Nord après la ville de New York.

==Tallest buildings by pinnacle height==

thumb|right|upright|[[One Prudential Plaza, the seventh-tallest building in Chicago when measuring by pinnacle height, with Two Prudential Plaza in the background]]

This list ranks Chicago skyscrapers based on their pinnacle height, which includes radio masts and antennas. As architectural features and spires can be regarded as subjective, some skyscraper enthusiasts prefer this method of measurement. Standard architectural height measurement, which excludes antennas in building height, is included for comparative purposes.
