Well, again, I already explained my own frame of reference/thinking, so I'll just point people back at it.
And, here's a list of every hero grouped by height:
- 5'1": Visionary
- 5'2": Tempest
- 5'4": Unity
- 5'5": Parse
- 5'7": Absolute Zero, Mr. Fixer, Nightmist, Wraith
- 5'8": Bunker, Medico
- 5'9": Captain Cosmic, Scholar
- 5'10": Argent Adept, Beacon, Fanatic
- 5'11": Chrono-Ranger, KNYFE, Ra (as Blake, 6'4" as Ra), Setback
- 6': Tachyon
- 6'1": Expatriette, GI Bunker, Grandpa Legacy, Naturalist
- 6'2": Legacy
- 6'5": Mainstay, Sky-Scraper
- 7'2": Haka
- 8'6": Fright Bunker
Honorable mentions go to Idealist who is 5'3" but still a growing kid, Omnitron-X who is 5' but a robot, and Guise and Writhe who are 5'10" and 5'5" respectively but also described as explicitly having varying heights.
