Since FR only show's your dragon's length, it's a little hard to gauge how tall they are. I've always been curious about it, and idk if anyone has done something this yet, so, I made a calculator for it. It's on google sheets, so make a copy to use it.
How I made it is by dividing the dragon's height in pixels by its length in pixels, you come out with a multiplier to calculate the height. The height is from the top of the head down to the front legs (back in the case of Wildclaws) and the length is from the base of the head to the tip of the tail. Since Undertides don't have any front legs, it just calculates how thick they are.
things I figured out: Ridgebacks are on average the tallest dragons. Imperials are in second. Snappers are the most "square", their height is the closest to their length
