The recognized titleholder for the tallest living man is Sultan Kösen, born on December 10, 1982, in Mardin, Turkey. Guinness World Records officially confirmed his height in February 2009 at 8 feet 1 inch, but subsequent measurements documented further growth until he reached his definitive height of 8 feet 2.82 inches (251 cm). Kösen also holds the verified record for the largest hands on a living person, measuring 11.22 inches (28.5 cm) from the wrist to the tip of his middle finger.
Kösen grew at a typical rate until age ten, when an overproduction of growth hormone altered his physical trajectory. His height prevented him from completing his schooling, leading him to work part-time as a farmer to support his family. Navigating the world at over eight feet requires custom-made tailoring, reinforced furniture, and specialized footwear, his shoes measure European size 62.
His unchecked growth finally halted between 2010 and 2012 through intervention by endocrinologists at the University of Virginia Medical Center. Doctors administered Gamma Knife radiosurgery to target the non-cancerous tumor responsible for his pituitary disruption, safely arresting his growth and stabilizing his physical condition. Today, Kösen travels globally as a cultural ambassador for Turkey, using his platform to promote public awareness around endocrine health.
