Thanks for the interest on my Robotech Size Charts. I am in the process of greatly expanding them, and I am trying to incorporate every mecha, vehicle and vessel that I can locate. I am adding more detailed charts for different scales, from as small as a Cyclone to as large as Dolza's ship. After I am completed the Robotech chart, I have tentative plans to construct one for Macross as well. If anyone has any mecha they would like to donate, or better pictures of ones I already have, please feel free to contact me.
For the dimensions, I have drawn upon two primary sources, macross.anime.net, and for the remainder, the Robotech Reference Guide and Robotech.com. The Deadalus on the side of the SDF-1 is smaller than the Daed by itslf, I believe the SDF-1 itself is slightly disproportionate. The Zentraedi height eems to fluctuate widely depending on the source, from 5x to 10x human height. I decided to use the dimensions for Milia from macross.anime.net. They seemed to indicate that her height and (ahem) measurements were 5x bigger when a giant, so I used the 'average' male height of 1.8 meters x 5. It does vary from Zent to Zent, and Breetai and Dolza are the exceptions.
Thanks to valk1j and chas for the Macross size comparson pics.
Most of the artwork is derived from various sources, such as Robotech.com, screencaps, art scans, etc. Much of the lineart is originally drawn by us. I will post some of them in hi-res on the color scheme thread in the next few days for those interested!!
