Where can I see how much memory the game is using?

How can I see how much space the game uses without downloading the game? (E.g. Fortnite. My friend says it uses 90gb but websites say it only uses 40gb)

It takes about 20 GB… 90 is complete nonsense and I don't know where you got the 40 GB from.

Something like that is quite easy to google.

What should be noted is that this article is 2 years old

So 20 GB may have changed

Right, my mistake, I thought I read in 2020 …

In that case, that's actually not true. Here is something more recent:

Are probably around 37 GB.
