I’ve been thinking a little bit. What are the biggest single clouds there are. I know cumulonimbus clouds are huge, but I feel that stratus may be even vaster. Which one’s bigger, or am I missing some?

Samuel, it all depends….
Google above and this is from the third thumbnail:

Samuel, you made me think a bit too. I think it may have been C. E. M. Joad (philosopher and psychologist) of the BBC’s Brains Trust who put into the language ‘It depends what you mean by…’. In CAS, and perhaps most cloud literature, we tend to concentrate on cloud type. As you point out, stratus (Latin for layer) inherently has a wider spread.
But to me your question implies a search for a boundary condition; if you find one you can then start quantifying – spread, height, perhaps weight etc. But I would bet it is not that unusual that you could fly across the Atlantic yet see no water beneath the cloud. Further, satellite pictures such as those from Meteosat, Terra etc can show cloud covering whole swathes of the globe.
So I fear your question as it stands has no simple answer.

On what criteria are we comparing clouds? Height, area covered, volume? I think the continuous nimbostratus in a hurricane can easily be bigger than any other cloud, except by height, A cumulonimbus can actually pierce the tropopause. But then, there can be Cb’s in hurricanes …
