I would like to have a uniform system of dragon lengths. Last night at my college's Hall Ball we were in the Pacific Science Center and I noticed the display say that the Allosaurus was ~28 feet in length. Being a DRoP nerd I of course had to compare that to dragons and claim, "Oh my. That's not nearly large enough to be a Brown" (which is currently listed as 29-35 undefined length units).
So then I look at meters. And that would make Ramoth and Kayleth behemoths of unreasonable size (upload.wikimedia.org/wikipedia/commons/b/bd/Longest_dinosaurs1.png). But even to look at Whites, which are just under 20 Length Units, if they are ~20 meters then they would be about this big (see below) and that seems too big too.
I agree with Dance on the fact that I think feet is better, because meters IS quite large. I mean, I'm all for Regganith being huge-normous, but even HE doesn't picture himself being THAT big. Feet are quite flattering for a dragon.
