His hands measure 10.8ins across and his feet are 13.7ins long.His feet aren’t much shorter than their legs.
So little wonder that the children of St Michael’s were treading carefully when Sultan Kosen came to visit.
Fortunately for them, the world’s tallest man is a giant of the gentle variety and careful where he puts his size 28s.
Pupils had to clamber up a climbing frame to make eye contact with the 29-year-old who is 8ft 3in tall.
Mr. Kosen, a farmer, visited the school in Twickenham, south-west London, after it won a Guinness World Records Educational Programme competition.
The Turkish farmer impressed teachers and pupils by ‘placing’ a ball in a basketball hoop while barely having to stretch. Pupils crooked their necks as they stared up at the giant man, who walks with a stick and is almost three times their size.
Mr. Kosen signed autographs and held a question and answer session with the youngsters and said he felt very welcome at the school
Sultan said: ‘Some people don’t know what to do when they meet me but everyone at St. Michael’s has been so friendly and warm.
Sultan’s hands measure a massive 10.8 inches across and his feet are 13.7 inches long, which are also world records.
He became the world’s tallest man in August 2009, when he shot past China’s Bao Xishun at 7ft 9ins.
Sultan suffers from a rare disorder called pituitary gigantism, which causes his body to continually produce the growth hormone.
His condition is believed to have been caused by a tumour in the pituitary gland.
Doctors thought they had cured him in 2008 when they removed the tumour but he continued to grow by half and inch a year.
Now medics say he has finally stopped growing.
