11. Broc Brown—7’8
The youngest giant on this list is 19-year-old Michigan teenager Broc Brown. Brown was only five years old when he was diagnosed with Sotos syndrome, a rare genetic condition that causes tremendous physical growth during the first years of life.
He grows six inches every year. He was 5’2 in kindergarten, 6 feet by middle school, and 7 feet when he reached high school. However, being young hasn’t prevented Brown from developing health issues like others on the list. His family also faces financial problems because custom-made clothes and shoes that fit his frame are costly and Brown grows out of them very quickly.
His local community raised $100,000 for clothes and shoes that Brown ended up outgrowing the following year. He says he eventually wants to find a job and live a normal life, despite his size.
