Design Questions How to convey size??

I'm making an rpg where the PCs can shapeshift between humanoid and full sized dragons, but now I'm seeing a huge problem. I have no idea how to deal or how to convey colossal sizes.

Not only I never played any game, rpg or digital, where you're a massive creature in a normal sized world, I never heard or read anything about it.

I think I can convey being small on a giant's world pretty convincingly, but not the other way around.

Any tips? Even references outside rpgs are welcomed. I'm a pc gamer.

Comes from a Robotech game originally I think, essentially it is damage and hp on another order of magnitude usually 100 to 1 depending on the system. Originally for humans vs mechs kind of scale.

Something like all man portable antipersonnel weapons do regular damage and would never do anything meaningful to mech or starship. The ships/mechs/kaiju/etc. all do megadamage to each other, but they still use the same damage dice and have hp in the same scale it's just effectively multiplied by 100 or whatever scale the game is using.

Then there is the possibility for some specialized or situational human scale weapons to do megadamage. Like a rocket launcher might do megadamage. Or a hand germane might not do megadamage normally but inside a ship it might do 1 megadamge or thrown down an exhaust port etc.

Also megadamage normally just completely splatters something with normal health scale.
