The tallest man living is Sultan Kösen (Turkey, b.10 December 1982) who measured 251 cm (8 ft 3 in) in Ankara, Turkey, on 08 February 2011.
The part-tme farmer was the first man over 8 ft (2.43 m) to be measured by Guinness World Record in over 20 years.
Indeed, GWR only knows of 10 confirmed or reliable cases in history of humans reaching 8 ft or more.
Sultan also holds the records for widest hand span and largest feet on a living person.
Speaking at the time of his entry into the Guinness World Records family he said: 'I never imagined I would be in the book, I dreamed about it, but it was still a huge surprise'.
