Book!canon Javert is really, noticeably, tall. Fandom normally supposes him to be around 6'5 or 6'6. However! Russell Crowe is just under 6', so for the sake of not stretching him massively out of proportion, we'll go with that. And under normal circumstances, the first thin anyone would notice about him is his air of authority, and truly piercing stare.
Gene - is around six foot, with charisma and personality that extends about a mile around his body, and makes him seem taller. It's probably the first thing people would notice about him too (and the fact that he'll probably be shouting about something). He's one of those people that stands out in any room, and fills any gaps with sheer force of presence.
Bruce Banner - is around 5'10. The first thing people would probably notice about him is how unprepossessing he is, and that he actively looks like he's trying to take up less space than he needs.
Bruce Wayne - about 6' even. The most obvious thing about him would be (if coming in from the office) how obviously well-tailored his clothes are, and how he reeks of money. If he's coming in from just a regular day, his physical fitness will probably show, as he'll be in sweats.
