If Cybertron is a planet of large cars and trucks, that can live in a large city the size of Texas. And lets say two of those large cities fit on Fortress Maximus, and if we want to guesstimate. Seven Fort Max = Half of Cybertron. How big is Unicron in scale with Earth? http://tfwiki.net/w2/images2/5/59/BlackHorizon2-Unicron.jpg Should he be bigger?
