When I first saw that chart in the video, I thought, "Holy shite! That is a 50-foot-tall Indominus rex! That's not right at all." But after actually looking at the chart and the measurements, I realized it isn't so bad.
Jeanie: 5 ft 4 in
Blue: 6 ft 1 in
Indominus: 17 ft
T. rex: 13 ft 1 in
Baby Stegosaurus: 5 ft 5 in
Blue's height is contradicted in Fallen Kingdom where she's recorded at 5-feet-6-inches, which is the same as on the JW size poster. It matches the 6 feet from the JW website, though. Lengths:
Jeanie: 13 ft 2 in
Blue: 15 ft 3 in
Indominus: 42 ft 6 in
T. rex: 41 ft 4 in
Baby Stegosaurus: 10 ft
What threw me off was the size of the T. rex. I was assuming she'd be 16-17 feet like every piece of official information has affirmed since the birth of Jurassic World, so with the Indominus looking nearly double the size, that'd be one huge beast. But this T. rex is rather small. Her length (on the size chart) is...meh, but her height is almost jarring. Under 13 feet is JP3 T. rex height, not Rexy height. The posture may be to blame here since she's almost completely parallel to the ground on the chart, with her head almost below the arch of her back, when she's usually at about a 10 degree angle in the movies, and the T. rex on the JP3 size chart is also around a 10 degree angle with his head up (also seen in the ILM special features on the DVD). Hopefully it really is just the posture, because that just contradicts so much visual and stated evidence to have a 13-foot-tall Rexy. Lol.
UPDATE 4/22: Huge thanks to the Jurassic Podcast for posting a video that included a solid look at the full size chart. All numbers in this post now are from the current chart. I was able to see more of the numbers clearer now, as well as add more of the animals in the Live Tour. However, it should be noted that there are clearly two different charts, as the numbers have changed between this newer one and the older one (I. rex has gotten smaller all around, T. rex has gotten taller but less lengthy, etc). I must get to the bottom of this!
