Dragons have different shapes and sizes when it comes to their bodies. They can be very small to enormous, typical type of body or an unusual type of body. There are some characteristics that are common to all Dragons as in all have scales and a tail, those too might differ slightly but are common. We all know of the common western dragon with 4 legs, tail, scales and sometimes horns, spikes and barbs. Not all western dragons have wings, but most do. They come in different colours depending on their species, habitat and clan. E.g. It's uncommon you'll find Blue dragons in a desert.
There are also dragons that have hair, and feathers. When a dragon with these features is spotted you'll notice many other differences. You'll even ask yourself if this is a dragon or not… It's very uncommon for dragons to have feathers instead of scales but there's a possibility the reason for this could be magickal. Dragon's aren't born with feathers or hair; it's later developed or usually the result of a magickal act. The hair on dragons has spread wide though as they bread more and more dragons are developing strange features. It's still rare to see these types of dragon but it's becoming more common.
The Oriental Dragons are known to have hair, and this is a sign of wisdom. Though, I can't see the possibility of a Oriental dragon mating with a Western, if it happened at all that would be another possibility to consider as how dragons started to grow hair. It's even uncommon for clans and species alone to mix, although it has happened dragons usually like to stick to their own kind. E.g.… A fire dragon would not mate with a water dragon.
Some people see rainbow-coloured dragons. Dragons that aren't only one colour. This too can be a sign of inbreeding. If a fire dragon mated with a mountain dragon you could end up with a pink dragon. I'm not saying it's certain, I'm just saying it could happen. Red + White = Pink. This could be why some dragons aren't all one colour.
Here are the basic body shapes and sizes, and the name of each one.
ranges from 10 to 30 feet from ground to shoulders in height, the body is proportionate to it's height, has only two hind legs, wings as their second set of limbs, long neck the length of the body ending at a narrow shaped head with long snout that comes to a point, typically they are a lot like birds in that they use their set of legs to hold down prey and rip it apart with its mouth.
having a body like that of a snake being from 15 to 45 feet long, they have no visible legs but instead have small wings where legs would be if they had them, the end of the tails are more oval shaped and have skin that comes off of it for directional control, these are an more aquatic dragon so they use the wings as flipper to move through the water, their main source of food are fish and other sea animals.

being similar to both a Wyvern and a Guivre they have hind legs and wings, what they differ in is that their wings are attached to front legs that are like arms with hand-like claws on the tips, this being similar to that of a bat, having a long neck ending in a rectangle shaped head, their bodies being enormous in size, ranging from 20 to 60 feet at the shoulders, the end of its tail has porcupine type quills, they spend most of their time in deep caverns away from everything else and survive by eating cave dwelling creatures.
