Hello how may I help you? I need to know about a world record! What would you like to know? Who is the tallest person in the world? Do you mean the tallest living person or the tallest person of all time? I guess who has the official record. Robert Pershing Wadlow was the tallest person in history How tall was he? He was 8 ft 11.1 in I bet there was some guy taller that just never measured himself. Thanks for your help. You are welcome
