Coming in at around 5 feet, 9.5 inches tall, Joseph Gordon-Levitt is average height. He makes the most of his inches by adopting perfect posture, though. Watch the way he moves, stands and sits. His back is military straight and his shoulders are pulled back. You can often see a slightly upward tilt to his chin that helps create a straight, clean jawline, too. If you want to look good when you're out and about, don't slouch -- stand up straight. This is one secret of good dressing you just can't buy.
