Here's a site that says the T. rex was 20 ft. tall, and the skeleton in the Visitor's Center was 40 ft. long, and to me, it looked like the female T. rex in the movie was bigger:

This site says that the animatronic T. rex in the theme park ride was 50 ft. long, and I believe they based it on the size of the one in the movie:

And this site isn't from the JP franchise, but talks about Jurassic Park and states the size of some larger Rex specimens at about 50 ft long:
