Sultan Kosen, a 26-year-old Turkish man, is now the officially recognized tallest man in the world. At 8ft 1in (2.47m) Kosen is about 4in (10cm) taller than the previous title-holder Bao Xishun. Kosen also has the largest hands and feet in the world. His hands measure 10.8in (27.5cm) and his feet 14.3in (36.5cm). Kosen's name will enter Guinness Book of Records for 2010.
On Thursday Guinness World Records confirmed Kosen's titles at the launch of the 2010 edition of the Guinness World Records book in London. A spokesman for Guinness World Records said Mr Kosen was the first person in more than a decade it had recognized as being more than 8ft in height.
Sultan Kosen grew normally until he was 10, but then a tumor caused him to develop a medical condition called pituitary gigantism, which affects hormone production and results in extreme growth, thickening of bones and large extremities. The tumor was removed last year and his growth stopped.
