In the Harry Potter universe, it's possible to have a tent that appears larger on the inside than on the outside. Is there any reason it wouldn't be possible to place one charmed tent inside another charmed tent? If that is possible, then wouldn't it be possible to place an unlimited number of charmed tents inside of other charmed tents, making an entire charmed tent universe? Furthermore, what limits the creation of charmed tents or charmed spaces in general, and is it possible to remain inside of one when they are folded up/destroyed? I know the Harry Potter universe goes into making seemingly small spaces very large on the inside (charmed tents, Mad-eye's prison), but does it ever go into placing a charmed space object into another charmed space object?
I don’t know why the comments weren’t posted as answers, but I’ll post this anyway:
In addition to the points mentioned in the comments — in particular, the fact that Hermione carried her bag into and out of the charmed tent many times — Hermione carried the tent in the bag:
“… You could get out the tent, Harry …”
“In the bag!”
“In the … of course,” said Harry.

So it appears that the answer is yes, you can place a charmed space object into another charmed space object.
No, probably not
We know that the fields at the world cup were packed with fans and tents so you have to ask yourself why didn't large groups put tents inside tents to give themselves more room? The only logical answer is that they can't.
Also you'd have to think that there would be a whole line of magical tents made for the very purpose of being a great place to set up your tents. If I could I would definitely buy a tent that's sole purpose was to provide a better place to set up my other magical tents. Giving me and my friends a central place to hang out a sort of shared common room if you take the main characters as an example. Where the girls are separated from the boys they could have had a common room to hangout together.
Yes, probably so
I really doubt there is any consistency to this, but if we operate under the assumption that the tents use the same charm as Hermiones bag it would make it impossible for Hermione to take her bag into the tent if this couldn't work.
So why wouldn't you?
As stated by @PeregrineRook It is obvious that you can indeed carry a tent within another extendable object, the real answer may be that witches(and wizards) know better than to get into a tent that is inside another extended object. Getting out of one tent in real life is hard enough if it collapses imagine a humongous tent that collapses onto another humongous tent that in turn collapses.
is it possible to remain inside of one when they are folded up/destroyed?
It definitely seems likely, throughout the entire Deathly Hallows book, multiple items seem to exist within the folded up tent and also within Hermiones bag, also Phineas Nigellus talks from within the bag when it is closed. I expect the point of not staying inside somewhere when it's folded is that you may never get out.
what limits the creation of charmed tents or charmed spaces in general?
Like most magic in Harry Potter there will probably be a limit of what can be done size wise, Hermione mentions that the charm she placed on her small bag was incredibly tricky.
The limits could be interpreted in two ways.
- The limit is dependent on the size of the item you are charming, I.E a small pouch ranging to a large tent
- The limit is dependent on the size of the space you want to create
Both points really have the same limit, if the size of the item you are charming is the limit then you won't be able to create a humongous space, if the space you want to create is the limit there's no point in charming something once that something is larger than the space you can create.
Without knowing if the charms are all the same and what the limits are for definite, we have no way to concretely ascertain whether or not you can open an extendable tent inside an extendable tent and so on and so forth. There are logical we can conclusions we can make to point towards both "yes you can" and "no you can't" we can also make some assumptions about the limits and whether or not you can stay inside once folder up.
Dont ask me where i got this from, i dont know and i might be wrong, but ill still just put it out here.
The extended space charm does not extend the space itself but instead links to another space. Which in theory makes it possible to "stack" tents in one another, this will however prove to not be a good thing if a whole lot of people in tents depend on a single entry tent.
