The current design – which includes the Starship and Super Heavy elements – measures just under 120 m (~390 ft) tall and 9 m (~30 ft) wide.
At present, SpaceX is building two full-scale prototypes of the model at their facilities in Boca Chica, Texas, and Cape Canaveral, Florida. These are designated as the Starship Mk. 1 and Mk. 2, which are expected to begin test flights to suborbital altitudes in the near future. When complete, these super-heavy launch vehicles will be the largest and most powerful rockets ever built.http://familystar.org.tw/index.php?option=com_smf&Itemid=45&topic=29021.0
