In a world built for average heights, a few rare individuals have towered far above everyone else. The tallest person ever recorded remains American Robert Wadlow, who reached 8 feet 11.1 inches (272 cm).
Born in 1918 in Alton, Illinois, to parents of normal size, he grew rapidly due to a pituitary gland condition that flooded his body with growth hormone. By age 8 he already outgrew his father. He kept growing until his death at just 22 in 1940, after an infection from a poorly fitted leg brace.
Second place and other giants
Close behind stands John “Bud” Rogan, who measured about 8 feet 9 inches (267 cm) in the late 1800s. Other notable figures include John F. Carroll and several men who approached or exceeded 8 feet 5 inches.
Most of these extreme cases stemmed from untreated or poorly managed pituitary disorders.
The tallest person alive today
Turkish farmer Sultan Kosen currently holds the Guinness World Records title for tallest living person at 8 feet 2.8 inches (251 cm). He has kept the record since 2009 and was reconfirmed in recent years including medical checks as late as 2026.
Like many before him, his height results from a pituitary tumor that caused excess growth hormone. Surgery helped slow further growth, yet everyday tasks remain difficult. He uses crutches and needs specially made clothing and shoes.
Women who reached extreme heights
The tallest woman ever verified was China’s Zeng Jinlian at roughly 8 feet 1.75 inches. Today’s tallest living woman, also from Turkey, stands significantly shorter.
Modern medicine can now treat the conditions that once produced these record heights, making it unlikely anyone will ever match Wadlow’s mark. Their stories highlight both the limits of the human body and the quiet challenges of living far outside the ordinary.
