Godzilla vs. Kong Trailer

I did not see the latest King Kong movie (Skull Island), but I did enjoy the new Godzilla movies. I am just confused about one thing: the height of each monster. Godzilla is supposed to be almost 400 feet tall, whereas Kong is 100. In this they look fairly even. I guess having Godzilla four times the size as Kong would be less appealing for posters and marketing.
