User blog comment:SuperNerd295/What should be the size of the new godzilla?/@comment-7622429-20150826162459

Just as Gareth Edwards said in interviews for his film, he didn't want to make Godzilla too big, so as to not completely tower over everything. He wanted his version of Godzilla to be huge, but still comparable to the average large building in this day and age.

With that in mind, and given that some of Godzilla's most famous foes clock in at around 120 meters or so in comparison to his previous largest appearance before G14 at 100 meters, I believe that should be the new standard for 2016's version.
