Young Barron Trump has already gone far beyond the average percentile in height for a boy his age. The median height, or 50th percentile for a 15-year-old boy in the United States is 66.9 inches, or just under 5'6". Barron has also surpassed the standard height prediction called mid-parental height using the combined heights of his parents (via Healthline). At about 6 feet 2 inches for his father and 5 feet 11 inches for his mother (via IB Times), this means you would combine this number in inches and divide by 2, then take that number and add 2. This would predict an adult Barron at about 6'3" — a height he's already overshot.

So just how tall will this towering teen be as an adult? Studies have shown that the peak height boys reach during puberty is about 92% of their total adult height (via Indian Journal of Endocrinology and Metabolism). If 6 feet 7 inches is this peak, then the math tells us Barron Trump may reach just shy of 6 feet 11 inches!
