Bestiary screenshot. The official in-game encyclopedia doesn't even explain sizes

Version is 1.16.5
Specifically lightning dragons. Is there a difference in size compared to fire and ice? How big are they? I'm asking for all 5 stages. I wanna know because I wanna make a dragon forge in my underground base so I gotta get measurements to make it slightly bigger. I just wanna avoid accidentally asphyxiating it or making an oversized room for it.
