Um Guys the actual scale of The command chair to the ops/conn on the galaxy bridge is pretty accurate. At least it feels like it is to me. As for the arguments about the size, maybe this is how they scale em in the 25th century? It doesn't make any difference in how the ship would run realistically, star trek bridge operations are totally illogical anyways as to how we would really create a bridge in a starship in the first place. why would for example, the tactical officer also become the communications officer? answer- the producers decided not to have a communications officer seperate from the rest in TNG for no real reason. Realistically tjhat would be the ONE station/officer that would NEVER get nixed on a real starssship- communications would not be running smooth letting it be done on automated Comm systems or by secondary officer control. But anyways the point is, you will never get a justified answer to the model scale of the bridge, it literally is a case of "It is what it is".
