The tallest President of the United States was Abraham Lincoln. He stood at 6 feet and 4 inches (1.93m) which is 9 inches (0.22m) taller than the average American born in the 1800s (5 ft 7in /1.71m)! Lincoln is only 0.5in taller than the second tallest President, Lyndon B. Johnson who was 6ft 3.5in (1.92m).
While Abraham Lincoln is the tallest US President ever, he is not the tallest to ever run for office. Winfield Scott, who ran against Franklin Pierce in 1852, was taller than any person that has ever run for President. Scott was 6 feet and 5 inches tall (1.96m) making him an inch taller than Abraham Lincoln. John Kerry who ran against George W. Bush in 2004 was the same height as Abraham Lincoln but both Winfield Scott and John Kerry failed to win their Presidential elections.
