composite indexes

Does composite indexes require more space during index creation than a single column index? If yes how?

Something is "bugging" me out.
When I tried to create a composite index on three columns I ran out of space. But if I use the same storage parameter to create a single column index, I do not run out sf space.

Yes, a composite index will take up more space, becuase of more data. Now, does it grow expoentially? I do not know.

Hello! Composite index would have to have more than one column and will require space for all teh columns plus a bit of overhead vs single column index which needs storage for one column and some overhead.
