If the main usable areas of all university buildings are added together, i.e. if all building space spread vertically over the floors is theoretically laid next to each other and if the space gained in this way is measured, this would then amount to 346,413 m² - or around 34.6 hectares.
This almost corresponds to the space taken up by the Stuttgart district of “Oberer Schlossgarten“, that comprises 36.4 hectares.
The Stuttgart district “University” in turn measures 46.0 hectares.
