I was misunderstood, likely because i used vague terminology. When i said "spacing between turns" i meant the center to center spacing of the conductor. So if you kept a .25" spacing for a .25" conductor, the center to center space is .5". If you use a .375" conductor and a .25" space, then the center to center space is now .625". The voltage stand-off is still roughly the same with .25" of air between the turns.

Clear now?
