This isn't going to be very helpful, but the BEST answer to this question is likely "whatever size you want it to be." Because SW is such an incredibly over-the-top cinematic setting that trying to shoehorn anything about it into defined measurements is just an exercise in futility.

It isn't often that I give that answer to such questions, but in a case like this I feel that it is appropriate, because of the setting. Plot is far more important than what hull size the Falcon can be shoehorned into, for this one. And if you want four seats in the cockpit, ok, there are four seats in the cockpit.

I absolutely love playing around with Spaceships, but that's my answer on this one.
