Dragon Sizes

[TL Wyvren]

There seems to be no end of contreversy on this subject. So...

[Vinom the God-King]

You want some controversy, Dragons can't be expected to be any larger than 15 feet, due to the fact every time you double the lenght, you quatruple the surface area, and octuple the mass, so we can't expect it to be larger than an engineless glider with a decent glide ratio...

[Sir Gawain of Orkney]

The one's that fly don't get much bigger than commercial aeroplanes, though size varies by species.

[Mithandir]

Well, in the Chasing the Sunset canon, the galaxy andromeda is in fact a dragon so ... I don't think your poll goes far enough

[Vinom the God-King]

This is a common misconception, dragons that large with out wing spands that would be inviable, unless they had a biological system similar to jet engines...

[Mithandir]

CtS gets around that by the dragons being full of hot air (well, not the celestial galaxy-sized dragons, the terrestrial kind).

[Vinom the God-King]

True... but they could also have subconscience magics that allow them to will away weight, but not mass.

[alric]

And as shown in recent CtS comic, dragons can change size, so I voted for all options

Well, dragon with size (meaning mass, wingspan, length ...) of commercial aeroplane would have minimal flight speed (stall speed) of commercial aeroplane. which is around 200km/h. Imagine landing in this speed. Imagine taking off in this speed (involving running, probably). Not probable. Luckily, weighting less that airplane is not so hard even with same length, not speaking about same wingspan ... and with lots of hot air it's really simple.

Of course, with magic there is no limit (which explains celestian dragons or space dragons like Granny). Also, with magic there are dragons able to change size (or shape ...).

And even the hot air might be too heavy :-). Some dragons do use hydrogen (created in digesting process) for both fire and flying - for example the ones from Dragon's World: A Fantasy Made Real.

don't forget the fact that the bones of the dragons are filled with air "p
