A note, the little guy waaaay on the left is a 6ft tall Human for size comparison. Enjoy!
Mech: Escaflowne
Anime: Escaflowne
Height: 8.09 Meters
Source: (In the Anime itself, the Mech is said to be "8.2 Costa in height" The producers have stated one "Costa" is equal to 0.987 meters.)
Mech: "Stage One" Gurren Lagann
Anime: Tenga Toppa Gurren Lagann
Height: 15 Meters
Source: (The office source books put out from the producers state the mech is "between 10 to 15 meters" I'd like to think it is on the bigger sized of things, so it is shown as 15 meters here)
Mech: The Iron Giant
Movie: The Iron Giant
Height: 15-30 meters (50-100ft ?)
Source: (All advertising regarding the Robot as well as reviews of the movie have the Giant listed at 100feet tall. However the production has the Giant listed at just 50 feet. Measurements and scaling of the Giant, especially when he is holding Hogarth, lend to the 50 foot size being more accurate. Though deep down we all know his heart is far far bigger!)
Mech: Giant Robot
Anime: Giant Robot - OVA
Height: 30 meters
Source: (The orginal show stated the robot to be 30 meters tall. The OVA giant Robot has been said to be similary sized)
Mech: Big-O
Anime: The Big-O
Height: 30 meters
Source: (Despite much desent from fans who think it should be bigger, the 'offical' height for Big-O is based off notes from produces captured on production sketches of the Mech where they wanted a robot "30 meters or 100feet" in size.)
Mech: MEGAS-XLR
Show: MEGAS-XLR
Height 35 meters
Source: (Despite many fans who think he is actually much SMALLER, the producers have stated they worked out his heigth one day by measuring the size of the car on it's head, a 1970 Plymouth Barracuda, aginst the rest of the Mech)
