The most consistent measurement for Rexy is 12 metres, or 40.35 feet. That's how large the animatronic is in the movie and is around the same length as the largest T. rex skeleton we have, which is FMNH PR 2081, nicknamed "Sue".

As for height, it depends on the pose, but in a neutral pose (slightly lower than the onscreen one), probably around 3.6 - 4 metres at the hips, probably 4.5 metres at the head. Higher figures are probably as a result of the pose.

As for mass, the official Jurassic World site lists her at 9,000 kg. Which, again, is about the same as Sue (8,830 kg).
