On 8 February 2011, Sultan Kösen (Turkey) is measured to stand at an impressive 251 cm (8 ft 3 in) in the Turkish capital, Ankara, confirming his status as the tallest human being on Earth. 
Stretching 28.5 cm (11.22 in) from the wrist to the tip of the middle finger, his hands also become record-breakers when they are verified as the largest hands on a living person. They span 30.48 cm (12 in) – about the size of a dinner plate!
Despite his lofty achievement, Kösen falls short of the tallest person ever, Robert Wadlow (USA), who when last measured on 27 June 1940, was found to be 2.72 m (8 ft 11.1 in) tall.
Sultan's giganticism was caused by a tumour in his pituary gland which led to an excess of growth hormone. In 2010, Sultan received life-changing brain surgery at the University of Virginia, USA and began medication for his hormone levels which ultimately led to the halting of his growth.
