Titan sizes range from slightly larger than a human, 7-15 meters for the regular ones seen, 60 meters for the Colossal and Wall Titans, and at least that guy that turned into a super-large Titan in the manga I've never looked at. One can expect the film to follow the anime/manga closely to heart.

Or be like the FMA franchise, being led to different paths as the story progresses.
