Abe Lincoln was 6 feet 4 inches tall. The 16th president of the United States, Lincoln is the tallest president in U.S. history as of 2014. Lincoln was a full foot taller than the shortest U.S. president, James Madison, the fourth President.
Lincoln's height was unusual for the middle of the 19th century, leading some historians to suspect he had Marfan syndrome, a genetic disorder. He was 7.5 inches taller than the average man during that time period, with the difference in height coming from his legs. This does not confirm that Lincoln had Marfan syndrome, but his height and the length of his legs did make him shaped like someone with the condition.
