P.S. It also raises the question of why the Enterprise NCC-1701 is considered a "heavy cruiser" or "battlecruiser", since a 300m ship would be a mere scout or destroyer in comparison to the older ships, in terms of tonnage.
Like a vessel at sea, in Newtonian physics, a larger starship would be harder to move with the same amount of thrust, making them something like a "dreadnaught" by comparison. We see several classes of these super heavy battleships, and no destroyers, departing Earth for Vulcan. So, the visual evidence supports a larger Enterprise, but logistical sense, which is what folks like Bernd Schneider consider, does indeed make things look less likely.
I've got no problem with people saying that they think the new ship should be the same size as the original, and that they think they made a mistake in upscaling it. My issue is with people ignoring a mountain of visual evidence and the stated word and intent of the ship's designers because they think they know better.
I think the majority of people who dislike the size would agree with this; they see it as a mistake, but don't ignore visual evidence or anything.
@USS Einstein for example argued that although he knows there is visual evidence of a large Enterprise "maybe we should ignore it, because Trekkies have ignored on-screen evidence in the past", or something to that effect. I would tend to agree. It wouldn't bother me either way greatly, but a 300m Enterprise just seems neat to me.
Thats why I would personally
"like" this chart to be official scale:
