It won't.  Ever.  Or at least, it shouldn't.  :-)  If it fills up, the
filesystem will deadlock, so the kernel _always_ preallocates space
for a transaction before allowing the transaction to start.  Only a
severe kernel bug could allow the journal to fill up, and such a bug
would not depend on the journal size.

That's probably fine.
