Tallest Man in the World – Heights, Records and Top 10 List

The title of tallest man in the world belongs to two different people depending on whether you ask about all of recorded history or only those still alive today. Robert Wadlow, who died in 1940, measured 272 cm (8 ft 11 in) and is recognized by Guinness World Records as the tallest human ever verified. Sultan Kösen, a Turkish farmer born in 1982, holds the current record for the tallest living man at 251 cm (8 ft 2.82 in). The gap between them is 21 cm, roughly the length of a standard ruler. Understanding who holds these records, how they were measured, and what the data actually shows requires separating historical fact from lingering uncertainty.

Extreme height in humans is almost always the result of a medical condition. In Wadlow’s case, hyperplasia of the pituitary gland caused continuous growth throughout his short life. Kösen’s height stems from a similar condition. Both cases fall under the umbrella of pituitary gigantism, a rare disorder that affects the body’s production of growth hormone. The records they hold are the result of rigorous verification by Guinness World Records, which applies strict measurement protocols before certifying any claim.

Who Is the Tallest Man in the World?

• Robert Wadlow remains the tallest human ever recorded, with irrefutable evidence from Guinness World Records.
• Sultan Kösen is the current tallest living man, but his height is almost 21 cm shorter than Wadlow.
• Only a few people in history have exceeded 8 feet in height, almost all due to medical conditions like gigantism or acromegaly.
• No new challenger has been confirmed for 2026, making Sultan Kösen likely to retain the title.
• Guinness applies standardized stadiometers and strict protocols before certifying any height claim.
• The distinction between “tallest ever” and “tallest living” is essential because the two records refer to different time frames.

Robert Wadlow: The Tallest Man Ever

Robert Pershing Wadlow was born in Alton, Illinois, in 1918. His growth began accelerating early: at birth he measured 0.76 m (2 ft 6 in), by age five he had reached 1.67 m (5 ft 6 in), and at thirteen he stood 2.45 m (8 ft 1 in). At the time of his death on July 15, 1940, at age 22, his height was recorded at 272 cm (8 ft 11 in). The cause was a septic blister from a faulty leg brace, which he needed because his size made walking without support impossible. Guinness World Records describes Wadlow as the tallest person “of whom there is irrefutable evidence.” His condition was pituitary gigantism combined with acromegaly, both stemming from hyperplasia of the pituitary gland. More details on his life and medical history can be found on Wikipedia: Robert Wadlow.

Sultan Kösen: The Tallest Living Man

Sultan Kösen was born in 1982 in Turkey and was verified by Guinness World Records in 2009 as the tallest living man at 251 cm (8 ft 2.82 in). He also holds the record for the largest hands, measuring 28.5 cm (11.22 in). Unlike Wadlow, Kösen’s growth was managed through medical treatment, which helped stabilize his height. He remains the tallest person alive as of 2025, with no verified candidate surpassing him. His biography is covered in detail on Wikipedia: Sultan Kösen.

What Distinguishes the “Tallest Ever” from the “Tallest Living”?

The difference is primarily temporal. The “tallest ever” record refers to the entire history of verified human height measurements. The “tallest living” record refers only to currently alive individuals. Wadlow’s height at death was 272 cm, while Kösen stands at 251 cm. That 21 cm gap means Wadlow was more than 8 inches taller than the current living record holder. Wadlow had already reached Kösen’s full height by around age 17 and continued growing for another five years.

How Tall Is the Tallest Man in the World?

Robert Wadlow’s Height (cm and feet)

Robert Wadlow’s peak verified height is 272 cm, which converts to 8 feet 11.1 inches. His growth was tracked throughout his life by Guinness World Records. At birth he was 0.76 m (2 ft 6 in). By age 9 he reached 2.12 m (6 ft 11.5 in). At 13 he was 2.45 m (8 ft 1 in). At 17 he stood 2.57 m (8 ft 5.5 in). In his final year, at age 21, he measured 2.65 m (8 ft 8.3 in). He died at 22 with a height of 2.72 m (8 ft 11 in). Detailed records of his progression are maintained by Britannica: Robert Wadlow.

Sultan Kösen’s Height (cm and feet)

Sultan Kösen’s height is 251 cm, or 8 feet 2.82 inches. This measurement was taken using standardized stadiometers as part of Guinness World Records’ verification process. He was first certified in 2009 and has been remeasured periodically since. His height remains stable due to medical management of his pituitary condition. The Guinness World Records page for Tallest Living Man provides the official measurement data.

Height Comparison: Tallest Man Ever vs. Tallest Living Man

Wadlow was 21 cm (8.3 in) taller than Kösen at his death. Wadlow reached Kösen’s height by around age 17 and continued growing for another five years. This means the tallest living man today is shorter than what Wadlow was as a teenager.

Who Is the Second Tallest Man in the World?

The Second Tallest Man in History

John “Bud” Rogan is the second tallest man ever recorded, standing at 267 cm (8 ft 9 in). He was born in 1867 in Tennessee and died in 1905 at age 38. Rogan was unable to stand due to ankylosis of his joints, so his height was measured while he was lying down. He remains the tallest person of African descent in recorded history. Unlike Wadlow, Rogan’s height was not verified by Guinness World Records during his lifetime, but historical sources place him at 267 cm.

The Second Tallest Man Alive

Morteza Mehrzad is the second tallest living man, at 246 cm (8 ft 1.5 in). He is an Iranian sitting volleyball player who competed in the Paralympic Games. His height has been verified by Guinness World Records. No other living person has been officially measured above 246 cm as of the latest available data.

Certainty vs. Uncertainty: What Do We Know for Sure?

Why Are These Records Important?

The title of “tallest man in the world” captures public fascination with human extremes. These records are medically significant because extreme height almost always results from pituitary gland disorders such as gigantism. Understanding these cases helps medical researchers study growth hormone regulation and its effects on the human body. Guinness World Records maintains strict verification protocols to ensure accuracy, separating verified facts from anecdotal claims. The clear separation between “ever” and “living” helps users understand historical reality versus current circumstances.
