Born in Detroit, Michigan, Harris was a 2005 Class A All-State fifth team selection as a sophomore by The Detroit News.
 He was an Associated Press Class A All-State first team selection in each of the next two seasons.
Harris was selected as the 2007 Mr. Basketball of Michigan.
 That season he led the Redford to the Michigan High School Athletic Association Class A championship game, which it lost to Saginaw High School.
During his high school basketball career, he became the first player to start for three consecutive Detroit Public School League championship teams since Jalen Rose and Voshon Lenard had done so from 1989 to 1991.
At Redford, Harris once recorded 52 points and 15 rebounds.
 During the 2006–07 season, his last at Redford, Harris averaged 33.5 points, 11.5 rebounds and 5.5 assists.
 Harris was highly recruited, receiving offers from Tennessee, UCLA, Wisconsin, George Washington, and Indiana before committing to the University of Michigan.
 He was ranked by Rivals.com as the sixth-best shooting guard in the country in the 2007 high school class, while Scout.com ranked him the twelfth-best shooting guard.
 ESPN ranked him #7, but they listed him as a point guard.
 When Michigan announced that it would replace Tommy Amaker with John Beilein as head coach, Harris was initially unsure if he would honor his signed letter of intent, but when Michigan re-signed assistant coach Mike Jackson, he again decided to attend the school.
