Honestly, the whole "Ridley is too big" argument bugs me on many levels; not just as a Ridley fan, but as a scientific person. In fact, if we use animals as a baseline, Ridley doesn't even get over 700 lbs; here's the best approximation I can get as to Ridley's dimensions;
If Ridley is 12 feet tall, that means he's most likely double that in both length and wingspan (as this is generally how saurians work); this means we have the following dimensions for Ridley;
- 12 feet tall.
- 24 feet long.
- 24 foot wingspan.
In order for Ridley to properly fly in Earth-like gravity (which I used to make the analysis easier), he
must be the same weight as or lighter than the largest volant animals on Earth; that being the pterosaur
Quetzalcoatlus.
Quetzalcoatlus weighs about 440-550 lbs (200-250 kilograms) with a 10-11 foot wingspan , so if we have Ridley play by those rules, he'd be about that weight or at most a little heavier due to his stockier proportions.
So here's the overall dimensions of Ridley, going by this analysis;
- 12 feet tall.
- 24 feet long.
- 24 foot wingspan
- 550-600 lbs (250-300 kg)/440-550 lbs (200-250 kg), depending on musculature.
To put this in perspective,
Tyrannosaurus rex (the closest dinosaur in size to Ridley at 13 feet) is up to 6.8 metric tonnes (14,991.4 lbs). Ridley is between
24.98 and
27.25 times as light as a
Tyrannosaurus. He ain't no heavyweight, that's for
damn sure.
As for his height and width....well, that's why proper scaling exists.
