In the books

This is how J.K. Rowling describes Harry Potter in Harry Potter and the Philosopher’s Stone:

“Harry had a thin face, knobbly knees, black hair and bright-green eyes. He wore round glasses held together with a lot of Sellotape because of all the times Dudley had punched him on the nose.”— PS, ch. 2
“The only thing Harry liked about his own appearance was a very thin scar on his forehead which was shaped like a bolt of lightning.”— PS, ch. 2
