Harry Potter
* Hair: Jet black, messy, and often unkempt.
* Eyes: Bright green, like his mother's. They are described as being very expressive and sometimes holding a "frightened, haunted look."
* Scars: He has a lightning-shaped scar on his forehead from Voldemort's attack.
* Build: Lean and wiry, somewhat small for his age. He is described as having "a long, thin face, with a crooked nose."
* Other: His appearance becomes more defined as he ages. He develops a "determined set to his jaw" and a more mature look as the series progresses.
Ron Weasley
* Hair: Red and fluffy, often unkempt. He has a habit of scratching his head, which often makes it stick up in odd directions.
* Eyes: Blue, bright and lively.
* Build: Tall and gangly, he's often described as being "lanky" and "clumsy."
* Freckles: He has lots of freckles on his face and arms.
* Other: Ron's appearance often reflects his current state of mind. When he's confident, he seems more put together, but when he's nervous or embarrassed, his hair and features seem to become even more exaggerated.
Hermione Granger
* Hair: Brown and bushy, often described as "frizzy" and "like a lion's mane."
* Eyes: Brown, large and intelligent.
* Build: Small and athletic, she's often described as being "neat" and "tidy."
* Teeth: She had a rather large front tooth that she later fixed in the "Goblet of Fire."
* Other: Hermione is often described as having a "bright, intelligent face" and a very serious expression.
Remember: The visual representation of the characters in the movies is just one interpretation. It's also great to imagine them however you personally envision them!
