Let’s cut right to the chase. When you ask “how tall is the biggest man in the world?” you’re asking about the tallest person alive right now. That title belongs to Sultan Kösen from Turkey. His official height, as verified by Guinness World Records, is a staggering 8 feet 2.8 inches (or 251 centimeters). But here’s the fun part: he’s not even the tallest man in history. Stick around, because we’re about to dive into a world of giants that will make you feel tiny.
Key Takeaways
- Tallest Man Living: Sultan Kösen of Turkey holds the current Guinness World Record at 251 cm (8 ft 2.8 in).
- Tallest Man in History: The tallest human ever recorded was Robert Wadlow from the United States, who reached an unbelievable height of 272 cm (8 ft 11.1 in).
- The Cause: This extreme height, known as gigantism, is almost always caused by a tumor on the pituitary gland, which floods the body with human growth hormone.
- The Distinction: It’s crucial to separate the living record-holder (Kösen) from the all-time record-holder (Wadlow).
So, Exactly How Tall is the Biggest Man in the World?
When we talk about Sultan Kösen’s height, 8 feet 2.8 inches is hard to visualize. Let’s put it in perspective.
- A standard doorway in the US is about 6 feet 8 inches. Sultan would have to duck by over a foot and a half to get through.
- He is taller than a classic red telephone box in London.
- If he were to lie down on the floor, he would be longer than most king-size beds (which are typically 6 feet 8 inches long).
Sultan’s size isn’t just about height; it’s about scale. He also holds the record for the largest hands on a living person, measuring 28.5 cm (11.22 inches) from his wrist to the tip of his middle finger. To give you an idea, that’s almost the length of a standard sheet of office paper.
His feet are no different. He wears a size 60 in European shoes, which is roughly a US size 25. His left foot, the larger of the two, measures 36.5 cm (14.4 inches). Finding shoes and clothes is, as you can imagine, one of the biggest challenges of his life.
Meet the Man: Who is Sultan Kösen?
Behind the record is a real person. Sultan Kösen was born on December 10, 1982, in Mardin, Turkey. For the first 10 years of his life, his growth was pretty normal. But then, everything changed.
A tumor developed on his pituitary gland, a condition known as “pituitary gigantism.” This tiny gland, located at the base of the brain, is responsible for producing growth hormone. The tumor caused it to go into overdrive, releasing a relentless flood of the hormone that caused his body to keep growing and growing.
He couldn’t attend school regularly because of his size and eventually became a farmer to help support his family, though his height made most physical labor difficult. For years, doctors tried to stop his growth. It wasn’t until 2010 that he found hope.
Sultan traveled to the University of Virginia in the United States, where doctors performed a groundbreaking procedure using Gamma Knife radiosurgery. This non-invasive technique focused beams of radiation directly at his tumor. As reported by the BBC, the treatment was successful. By 2012, doctors in Turkey confirmed that Sultan Kösen had finally, mercifully, stopped growing. This intervention likely saved his life, as his body’s framework simply couldn’t support continuous growth.
The Giant of History: The Unbelievable Robert Wadlow
As tall as Sultan Kösen is, he stands in the shadow of one man: Robert Pershing Wadlow. Known as the “Giant of Illinois,” Wadlow is the tallest human being in recorded history for whom there is irrefutable evidence.
When he died at just 22 years old in 1940, Wadlow measured an astonishing 8 feet 11.1 inches (272 cm).
Like Kösen, Wadlow’s incredible size was due to an overactive pituitary gland (specifically, hyperplasia of the gland). But unlike Kösen, Robert lived in an era before modern medicine could intervene. There was no surgery, no radiation therapy to halt the process. So, he just kept growing.
His life was a statistical marvel:
- By age 5: He was already 5 ft 4 in (163 cm) and wearing clothes intended for teenagers.
- By age 8: He was taller than his own father, standing at 6 ft 2 in (188 cm).
- At his high school graduation: He was 8 ft 4 in (254 cm).
Wadlow was known as a “gentle giant.” He was a quiet, mild-mannered man who enjoyed photography and playing the guitar. However, his extreme size took a terrible toll on his body. He required leg braces to walk and had little feeling in his feet.
Tragically, this lack of feeling led to his early death. In 1940, a faulty leg brace rubbed a blister on his ankle. He didn’t feel the injury, and the blister became severely infected. The infection spread, and his body, already under immense strain, couldn’t fight it. He died in his sleep on July 15, 1940. At the time of his death, there was no indication that his growth had ever stopped.
Kösen vs. Wadlow: A Tale of Two Giants
It’s fascinating to compare the tallest man alive with the tallest man in history. While their conditions were similar, their lives and outcomes were vastly different, primarily due to medical science.
| Feature | Sultan Kösen (Living) | Robert Wadlow (History) |
|---|---|---|
| Max Height | 8 ft 2.8 in (251 cm) | 8 ft 11.1 in (272 cm) |
| Nationality | Turkish | American |
| Cause | Pituitary Gigantism (Tumor) | Pituitary Hyperplasia |
| Lifespan | 1982 – Present | 1918 – 1940 (Died at 22) |
| Medical Status | Growth successfully halted by surgery | Was still growing at time of death |
Because of modern medicine’s ability to treat pituitary tumors, it is highly unlikely that anyone will ever break Robert Wadlow’s record. We can now stop the growth before it becomes life-threatening.
The Daily Life of a Modern-Day Giant
For Sultan Kösen, life is a series of obstacles. While his fame has brought him opportunities to travel the world, the day-to-day logistics are a constant battle.
- Clothing: Everything must be custom-made, from his suits to his size 25 shoes.
- Transportation: Fitting into a regular car is impossible. Air travel requires special arrangements.
- Home Life: His family home had to be modified with 10-foot ceilings and specially-built furniture just so he could live with some comfort.
- Health: Like Wadlow, his sheer size puts enormous pressure on his joints. He often uses crutches or a cane to walk, which helps to relieve the strain on his knees.
But it’s not all negative. His status as a Guinness World Records holder has made him a global celebrity. He has served as a cultural ambassador for Turkey and has met people from all walks of life, including the world’s shortest woman, Jyoti Amge. Their photos together are a powerful illustration of the incredible range of human diversity.
Frequently Asked Questions (FAQ)
Who is the tallest woman in the world?
The tallest living woman is Rumeysa Gelgi, who is also from Turkey. She stands at 7 ft 0.7 in (215.16 cm). Her condition is different from Sultan’s; she has a rare genetic condition called Weaver Syndrome, which also causes rapid growth.
Is Sultan Kösen married?
Sultan was married. In 2013, he married Merve Dibo, a Syrian-born woman who is 5 ft 9 in (175 cm) tall. He famously said he was overjoyed to find a partner who “fit” him emotionally. However, the couple reportedly divorced in 2021, citing language barriers and other differences.
How many people have ever reached 8 feet tall?
It is extremely rare. Throughout medical history, there are only about 10-15 well-documented, verifiable cases of humans reaching a height of 8 feet or more. Robert Wadlow and Sultan Kösen are just the two most famous examples.
What size shoe does Sultan Kösen wear?
He wears a European size 60, which is roughly a US size 25. His feet are over 14 inches long. Finding shoes that fit is one of his biggest expenses and difficulties.
Conclusion
So, how tall is the biggest man in the world? The man currently walking the Earth, Sultan Kösen, is an incredible 8 feet 2.8 inches tall. But the king of all giants, Robert Wadlow, remains the tallest human who ever lived, at a mind-boggling 8 feet 11.1 inches, a record that will almost certainly never be broken.
These aren’t just statistics; they are the stories of men who navigated a world that wasn’t built for them. While we gawk at their height, it’s their resilience that is the truly giant part of their story.
