Hello how may I help you? I have a world's records question Sure I can help with that, what is your question? Who's the tallest person in the world? Do you want the tallest living person or the tallest person of all time? Today The tallest person alive currently is Sultan Kosen, he is 251cm (or 8fet 3in) tall. How tall is his wife? His wife is of a much more normal stature at 5 foot 3 inches tall. Oh okay thank you! You are welcome, have a great day.
