The Home One is 3km long, and wingless. Its twice as long as an ISD, but its lightly armed and is mainly a carrier/command ship.
The two other types of Reb cruiser are each about 1km long. One has wings (often called Liberty Class), one is wingless (often called Independence Class). However, none are exactly identical, they have different numbers of engines, etc.
